What this fixes

Raw error text was being sent to PostHog. When the terminal UI shows an error, it also reports that error to our analytics. Until now the report included the error's full text. For a file error, that text is the complete path on the user's machine (their home directory and repository name included); for a network error it is the URL. Our analytics board only ever uses the error's category, so this text was sent for no benefit and against our rule that no file names or paths leave the machine.

The report now sends only the category, the severity, and whether the automatic repair worked. The full text still goes to the local errors.log, where it is useful for debugging.

The "commands report their real result" change (#112) had no test guarding it. Each command's analytics event is closed by a helper that records whether the command failed. If someone reverted a command to the old one-liner, every failure would silently report as a success again and no test would notice. A new test scans the command package and checks that every event, including any added later, is closed with the helper from a function that declares a named error.

Why it matters

  • Privacy: no path, URL or message text from the user's environment reaches the analytics service.
  • Reliability of the error-rate dashboard: a future edit cannot quietly break the failure reporting.

Since the first review

  • The telemetry call is passed into an unexported report() instead of being a package variable the test swaps, so there is no shared state for a parallel test to race on.
  • The wiring test parses the package instead of matching lines: every telemetry.NewEvent call, found by the package's import path so an alias is seen too, however it is written, must be assigned in a top-level function's body and followed on the next statement by the finishCommand defer, in a function returning a named err. A command written a new way, or added, is held to the rule; a trailing comment or a multi-line call is no longer a false failure. The test fails if any command is put back on defer te.Finish().

Tests

  • TestReportSendsOnlyTheKind: reports an error containing a path and checks the telemetry call contains none of it, and that the local errors.log still does; once for the fallback class and once for the build-gate class, whose headline is the error's own first line.
  • TestEveryCommandEventIsFinishedWithItsResult: every telemetry event in cmd/kai is closed with finishCommand on the next line, from a function with a named err.
  • go test ./internal/tui/... ./cmd/kai/ passes.

Decision for the analytics owner

Error events now carry empty headline and raw_message. The error_seen board groups on kind only; anything outside this repo that read those two fields would see empty values from the next release on.

The PR adds an AST-based test for command telemetry event finalization and changes error reporting to send only classified error data, repair status, and severity. Tests verify telemetry redaction and suppressed reports.

Changes

Telemetry controls

Layer / File(s) Summary
Error telemetry redaction
internal/tui/errors/report.go, internal/tui/errors/report_test.go
Report uses an injectable telemetry reporter. It sends only the error kind, repair status, and severity. Tests verify that sensitive error details are omitted and empty or "none" classifications are suppressed.
Command event finalization
cmd/kai/telemetry_wiring_test.go
An AST-based wiring test checks string-literal event names, named error returns, immediate finishCommand(event, err) defers, recognized event calls, and at least ten discovered events.

Summary

This PR prevents sensitive error details from reaching PostHog while preserving them in local logs, and adds a package-wide regression test for command telemetry finalization.

  • Sends only error kind, severity, and automatic-repair status to telemetry.
  • Keeps headlines, raw messages, contextual data, paths, and URLs local.
  • Verifies every command telemetry event is finalized through finishCommand from a function with a named error return.
  • The previously reported event-scan gap is fixed, and its thread is resolved.

Kai review

Kai Summary

Read through this one. 3 things worth your eyes before it merges, plus 2 decisions to say yes to. 👇

A clean, well-guarded privacy fix that stops raw error text from reaching PostHog and pins the command-result wiring with a source-scan test; no defects, but the analytics-side confirmation that nothing reads the now-emptied fields is a human's to give.

Decisions

Correct as written, but somebody should say yes to these:

  • This changes what every telemetry-enabled user (default on) sends for classified errors: headline, raw_message, and context become empty for error events, keeping only kind, severity, and the auto-repair flag. The author states the error_seen board groups on kind alone; any dashboard, export, or alert outside this repo that joins on the dropped fields would break silently (empty values, n…
  • ue.Context is now always sent as nil; the change assumes it is "never populated," but if any call site sets UserError.Context expecting it to reach telemetry, that structured data is silently dropped with no test catching it.

Full read-through

Scope: kaicontext/kai-cli, at the merge commit that adds cmd/kai/telemetry_wiring_test.go, internal/tui/errors/report_test.go, and rewrites internal/tui/errors/report.go. The PostHog sender itself (engine.ReportError) lives in github.com/kaicontext/kai-engine, which is outside this repo and which I could not read; the argument order is confirmed consistent between the call site, the pre-change call, and the test's swap, so the unverifiable part is only the engine's own field handling of those arguments.

What this does: Report used to forward ue.Headline, ue.LogContext (which is err.Error()), and ue.Context to telemetry. It now forwards empty strings and a nil map for all three, sending only ue.Kind, the severity name, and the auto-repair flag. A test intercepts the (now swappable) reportError package var and asserts a path-bearing error's text never reaches the call. Separately, a source-scan test reads cmd/kai/main.go and asserts every te := telemetry.NewEvent(...) is followed on the next line by defer func() { finishCommand(te, err) }() and lives in a function declaring (err error) {. My overall take: this is a clean, well-scoped privacy fix with a genuinely useful wiring pin. The two things I'd flag are a future-proofing note and an inherent limit of source-scan tests, not defects in the code as it stands.

Concerns:

  1. internal/tui/errors/report.go:43 — the indirection is a process-wide mutable global, and the test mutates it without serialization. reportError is a package-level var holding a function pointer, and TestReportSendsOnlyTheKind reassigns it with reportError = func(...) and restores it in t.Cleanup. Go runs tests within a package serially by default, so this is safe today, but the pattern is a data race waiting for the day someone adds t.Parallel() to a sibling test in internal/tui/errors. The LogLocal path right above it already locks logMu for its file write, which signals this package is conscious of shared mutable state. Not blocking — flagging it because the cost of the race, if it ever fires, is a flaky test that silently sends or swallows telemetry, which is hard to diagnose.

  2. cmd/kai/telemetry_wiring_test.go:21 — the regex only matches te := telemetry.NewEvent(...), so a future command that assigns to a differently-named variable (e.g. ev := telemetry.NewEvent(...)) would bypass finishCommand and pass the test. The test's purpose is to pin the wiring so a regression can't slip in unnoticed. A command written as ev := telemetry.NewEvent("foo") followed by defer ev.Finish() would not match the open regex, would not be counted in seen, and the len(seen) < 10 floor would still pass as long as the original ten remained. The guard against that is the len(seen) < 10 sentinel — but only if the new command replaces one of the ten rather than adding an eleventh. This is an inherent limit of source-scan tests, not a bug; I'd note it so a future maintainer knows the test covers "these ten commands stay wired" rather than "any new command must be wired."

  3. cmd/kai/telemetry_wiring_test.go:35 — the 4-line backward window assumes NewEvent is within 4 lines of the func line. This holds for all ten commands today (verified: each has the event on line 2 or 3 of its function body). But a command that does a couple of setup calls before opening the event would silently fail the func-line walk — the loop exits without finding a func line within the window and reports nothing, so the named-return check is skipped rather than failed. Same verdict: not a defect now, worth a one-line comment so the next person who moves a NewEvent down past line 4 understands why the named-return assertion stopped firing.

Verification of the fix itself: I confirmed all ten commands (init, capture, snapshot, ci_plan, status, diff, push, fetch, pull, shadow_run) open with te := telemetry.NewEvent(...) and close with defer func() { finishCommand(te, err) }() on the immediately following line, and all ten enclosing functions declare (err error) {. The test would fail if any of those lines reverted to defer te.Finish() — the closeOK string comparison would miss — so the test genuinely guards the regression it claims to. The TestReportSendsOnlyTheKind test would fail if Report were reverted to pass ue.Headline/ue.LogContext/ue.Context (the s.headline != "" assertion and the acme/salaries substring sweep would both trip), so that fix is also genuinely guarded.

Decisions (none of these are defects):

  • Privacy posture changed for every telemetry-enabled user. Before this change, classified error reports carried the error's headline, raw message, and context map to PostHog; after it, they carry only kind, severity, and the auto-repair flag. This affects every user with telemetry enabled (the default is on, per the Report doc comment) and means the error_seen board and any downstream consumer lose raw_message, headline, and context for error events. The author states the board groups on kind alone and never used the other fields; I cannot confirm what queries or alerts outside this repo read those fields, so someone who owns the analytics should confirm no dashboard, export, or alert keys on headline/raw_message/context for error_seen events. If the board truly groups on kind only, this is pure gain; if anything joins on those fields, it breaks silently because the values become empty rather than absent.
  • ue.Context is now always sent as nil for error reports. The change assumes it is "never populated" (report.go:49 comment). Within this repo the only caller of Report is internal/tui/views/repl.go:2078; whether that site or any path that constructs a UserError ever sets Context is the load-bearing fact. The comment claims it is never populated, but if a classifier rule or a future call site sets Context expecting it to reach telemetry, that structured data is now silently dropped on the floor with no test catching it. Worth a one-line confirmation that no UserError{... Context: ...} exists in the codebase today.

What's done well: the reportError package-var indirection is the right shape for testing a telemetry sender without standing up PostHog; the test's path-bearing secret and the acme/salaries substring sweep are exactly the right way to prove "none of it reached the call"; and the wiring test is a clever way to pin behavior the classifier tests structurally cannot see. The doc-comment update on Report honestly documents the three rules whose headlines carry raw text, which is the kind of "why, not what" that prevents a future contributor from re-adding the field.

This is solid. The two real items are a future-proofing note on the mutable global and an inherent limit of source-scan tests that's worth a comment; neither is a defect in the code as it stands. The privacy decision is the one thing I'd want a human to sign off on, and only because the analytics consumers live outside this repo.

Ready to merge once someone who owns the error_seen dashboard confirms nothing reads headline/raw_message/context on error events — that's the one fact I could not verify from here.

the 4-line backward window for the func line silently skips the named-return check if NewEvent ever moves more than four lines into the function body.

Scan to the enclosing function boundary.

If setup code places te := telemetry.NewEvent(...) more than three lines after the function declaration, the loop does not find the declaration and silently skips the named err return check. Map each event to its enclosing function with go/parser, or scan back to the actual function boundary.

No proposed defect was confirmed by this check within the reviewed scope.

This review is incomplete. The following could not be confirmed or cleared, for the reason given. No fix is proposed for them:

  • internal/tui/errors/report.go:51 — passing nil for Context with the comment "Context is never populated" is an unverified universal; UserError.Context is documented and designed to carry structured telemetry fields, and a rule that populates it would have its fields silently dropped from PostHog while still landing in the local log. — The evidence confirms three facts: (1) report.go line 51 passes nil for Context with the comment 'Context is never populated; nothing to send' (Source 3, line 51); (2) UserError.Context is documented in classify.go lines 83-86 as carrying 'mode, tool name, turn number, etc.' and is 'Whitelisted to avoid accidentally shipping PII' (Source 14, lines 83-86); (3) log.go line 89 still forwards ue.Context into the local errors.log (Source 30, line 89). The critical question — whether any classification rule actually populates Context today — cannot be resolved from the evidence. The visible 131 lines of classify.go show that neither the known-error path (lines 99-101) nor the unknown-error path (lines 103-116) sets Context, and classifyKnown begins at line 124 but is truncated. 330+ lines of classification rules remain unread and could contain a rule that sets Context. If such a rule exists, the nil in report.go would silently drop those fields from PostHog while they still land in the local log. The comment 'Context is never populated' is indeed an unverified universal given this evidence gap.
  • internal/tui/errors/report.go:45 — the privacy guarantee rests on kai-engine's ReportError forwarding exactly its arguments and deriving nothing else from the error; that repo is outside this review's reach and no matching engine-side change is mentioned in the PR. — The evidence confirms that ReportError is re-exported from the sibling repo: api/telemetry/telemetry.go line 8 sets ReportError = engine.ReportError, importing github.com/kaicontext/kai-engine/telemetry (Source 4, lines 4-8). A grep for 'func ReportError' across the kai-cli repo returned zero matches (Source 6, rows 1-6; Source 9, rows 1-4), confirming the implementation lives in kai-engine, not in this repo. The call site in report.go (Source 3, lines 45-51) does pass empty strings and nil for headline, raw, and context — this is verifiable. However, whether the engine's ReportError forwards exactly those arguments without attaching additional data derived from the error or from other sources is a claim about the kai-engine implementation, which is outside this review's boundary. The PR's 'Related' section (Source 1, lines 28-30) mentions a matching change in kai-tui but names none in kai-engine. This is a genuine limitation of the review's reach, not a defect in the diff's code — the call site does what it claims at the layer this repo owns.

Limitations

  • Could not read github.com/kaicontext/kai-engine/telemetry where ReportError is actually defined; the engine's forwarding behavior and PostHog schema are outside this review's boundary
  • Only lines 1-131 of classify.go were visible (330+ lines remain unread); whether any classification rule in the unseen portion populates UserError.Context is unresolved
  • Did not read cmd/kai/code.go, cmd/kai/do.go, or internal/tui/views/gate_review.go in full to verify the nature of their ReportError graph edges; text greps for 'telemetry.ReportError' in those files returned zero matches, suggesting the graph links may be indirect through errors.Report
  • Did not run review_shell; all Go claims are based on reading the source files directly

Decisions (need your call)

  • The author is deciding to drop ue.Context (structured, whitelisted telemetry fields) from the PostHog send entirely while keeping it in errors.log. If any classification rule populates Context today, the analytics board loses the ability to slice that error's occurrences by the fields that rule set; the author should confirm no rule uses Context or choose to forward it.

Kai review

Kai Summary

Read through this one. 2 things worth your eyes before it merges, plus 1 decision to say yes to. 👇

Where I'd land: 4/5 — your call, then merge.

The privacy change is correct and both tests genuinely catch reverts; the only thing needing a human's sign-off is the documented contract change that empties headline and raw_message on every PostHog error event.

Decisions

Correct as written, but somebody should say yes to these:

  • Error telemetry now sends empty headline and raw_message to PostHog; any external consumer of those fields outside this repo will see empty values from the next release. The internal error_seen board groups on kind only and is unaffected.

Full read-through

I read kaicontext/kai-cli at the working tree containing this change. The one thing I could not read is the engine's own ReportError implementation in the sibling module github.com/kaicontext/kai-engine (v0.6.72, a go.mod dependency, not vendored here) — so I cannot confirm from source that ReportError's parameter list matches the new send parameter type position-for-position. I rely on the fact that the pre-existing code already called telemetry.ReportError with the same argument order, so the change is a refactor of a call that already compiled; whether any external consumer of the PostHog events reads the two now-empty fields is also outside this workspace.

What this does

Report now delegates to an unexported report(...) whose fourth argument is the telemetry send function. report forwards only Kind, the auto-repair flag, and severity; it passes "" for headline, "" for the raw message, and nil for context. The raw string and headline still go to LogLocal (the on-disk errors.log), unchanged. A second test parses cmd/kai with go/parser and asserts every telemetry.NewEvent call in a non-test file is a string-literal event assigned to a plain variable in a top-level function that returns a named err error, immediately followed by defer func() { finishCommand(v, err) }().

My overall take: this does exactly what it says. The privacy change is small, correct, and the local log is preserved. The wiring test is genuinely stronger than a regex — it walks the AST and would catch a revert to defer te.Finish() as well as any newly added command written the old way. I verified all 10 current call sites (init, capture, snapshot, ci_plan, status, diff, push, fetch, pull, shadow_run) satisfy the rule the test enforces, and both tests fail on the unfixed code.

Concerns

1. The wiring test can be defeated by one extra statement between the event and the defer. cmd/kai/telemetry_wiring_test.go:66 requires isFinishDefer(stmts[i+1], v.Name) — the finishCommand defer must be the immediately next statement after the NewEvent assignment. All 10 current commands satisfy this, but the test will reject a legitimate future command that inserts any statement between the two — e.g. a ctx, cancel := context.WithCancel(...) placed after the event, or a defer for a closer registered before the telemetry defer. The author's own comment (line 22) says the rule is "followed on the next statement by defer func() { finishCommand(...) }()," so this strictness is intentional, but it's stricter than the invariant it protects (the invariant is "every event is closed by finishCommand," not "finishCommand is the very next line"). The consequence is a false failure on a well-written future command, which will pressure someone to weaken the test rather than reorder their code. I did not run the test against a synthetic future command, so I cannot show the failure concretely; the conclusion follows from reading the index-bound check at line 66 together with isFinishDefer, which only inspects the single statement passed to it.

2. eventLiteral reports the wrong defect for multi-argument NewEvent calls. cmd/kai/telemetry_wiring_test.go:94-96 returns false when len(call.Args) != 1, which the caller at line 53-56 surfaces as "the event name must be a string literal." Today every call is telemetry.NewEvent("init") (one string arg), so this passes; if the engine's NewEvent ever gains an optional second argument and a command uses it, the test flags the event name as a non-literal rather than saying "unexpected arity." I cannot see NewEvent's signature in kai-engine to confirm whether a second argument is plausible; within this repo every call site uses one arg, so this is a diagnostic-quality issue, not a correctness bug.

Decisions

  • Error telemetry now sends empty headline and raw_message to PostHog. The author names this in their own notes. Who it affects: anyone outside this repo (a sibling service, a downstream dashboard, or an external consumer of the PostHog events) that read those two fields will see empty values from the next release. The error_seen board groups on kind alone, so the internal board is unaffected, but I cannot see what else reads these events — the kai-engine side that emits/forwards them is outside this workspace. This is a deliberate, documented contract change to the analytics payload; confirm no external consumer depended on the two now-empty fields before shipping.

What's done well

The refactor to pass the send function as a parameter rather than swap a package variable is the right call — TestReportSendsOnlyTheKind has no shared mutable state, so it's safe under t.Parallel() without any synchronization, and the test reads as a direct assertion on what was sent. The test is also a real regression guard: with the fix removed, report would forward ue.LogContext (the full path) and ue.Headline ("Couldn't read /Users/someone/acme-payroll/..."), so s.raw != "" at line 35 fails and strings.Contains(s.raw, "acme") at line 39 fatals — both paths catch the leak. The choice to keep LogContext/Headline flowing into LogLocal while stripping them only from the telemetry send is exactly the right boundary. And the AST-based wiring test is meaningfully more robust than the "match te := within three lines" approach it replaces — it holds every future command to the rule regardless of how the event variable is named, and the accepted-pointer-keyed two-pass design correctly avoids both missing nested calls and double-counting top-level ones.


This is ready to merge from the code side. The one thing that wants a human's yes is the analytics-payload contract change (empty headline/raw_message on every error event from the next release) — that's a decision, not a defect, and it's already flagged in the PR. The test-strictness note on stmts[i+1] is worth a follow-up but isn't blocking.

eventLiteral reports "must be a string literal" for any NewEvent call with more than one argument, a misleading diagnostic if the engine ever gains an optional second parameter.

Resolve the telemetry package by import instead of identifier text.

isNewEvent accepts only a selector whose receiver is the identifier telemetry. A command file can import the package as tm and call tm.NewEvent(...); both scan passes then ignore the call. An event without the required finishCommand defer can therefore pass this test.

Resolve selector receivers against the file's telemetry import alias, or use type information to identify the NewEvent symbol.

Kai review

Kai Summary

Read through this one. One thing worth your eyes before it merges, plus 1 decision to say yes to. 👇

Where I'd land: 4/5 — your call, then merge.

A sound privacy fix that stops raw error text and headlines from reaching PostHog while keeping them in the local log, pinned by two genuinely behavioral tests; one decision needs the analytics owner's sign-off because downstream consumers of those two PostHog fields will see empty values from the next release.

Decisions

Correct as written, but somebody should say yes to these:

  • Error events now carry empty headline and raw_message to PostHog. This affects every downstream consumer of the error_seen board outside kaicontext/kai-cli — they will see empty values for those two fields from the next release on. The kind grouping the board relies on is unaffected. The analytics owner should confirm no consumer outside this repo reads those fields.

Full read-through

I reviewed kaicontext/kai-cli at commit 72a28ae (plus cmd/kai at e132167). The change touches internal/tui/errors/report.go, internal/tui/errors/report_test.go, and cmd/kai/telemetry_wiring_test.go. One external fact I could not verify: telemetry.ReportError is a re-export of github.com/kaicontext/kai-engine/telemetry.ReportError (a sibling repo not in this workspace), so I'm taking the existing 6-argument call order — which the old code already used and the new send closure matches argument-for-argument — as the contract rather than reading the engine's source.

What it does: Report now forwards only the error's kind, severity, and autoRepaired flag to PostHog; headline, raw (err.Error()), and ctx are sent as empty/nil. The full text still goes to the local errors.log via LogLocal (unchanged). The telemetry call is moved behind an unexported report(...) that takes send as a parameter, so the test injects a recorder without swapping package-level state. Separately, a new AST-parsing test in cmd/kai enforces that every telemetry.NewEvent(...) call is the assignment of a string-literal event name, immediately followed by defer func() { finishCommand(v, err) }(), in a function whose single named return is err error.

Overall take: This is a clean, well-scoped privacy fix with a genuinely useful wiring guard. The telemetry-report change is sound and both tests verify the behavior they claim. I have one concern about the wiring test's robustness and one decision to hand back.

Concern — the wiring test only walks a function's top-level statements, so a NewEvent opened inside a nested block gets a misleading error. cmd/kai/telemetry_wiring_test.go:46 iterates fd.Body.List — the function's direct children only — to find NewEvent assignments and verify the next sibling is the finish defer. A NewEvent opened inside an if, for, or nested block is an ast.AssignStmt that is not a direct child of fd.Body.List, so the main loop skips it; it's then caught by the ast.Inspect sweep at line 79 as "not accepted" and reported with the error at line 80: "a telemetry event must be opened as v := telemetry.NewEvent(...) in a command's own body." That message implies the problem is the assignment shape, when the real issue is nesting. The test still fails loudly rather than silently, so this is a false-error/ergonomics issue, not a hole that lets a buggy command ship — but if a future command legitimately needs to open the event conditionally, the test will need a real update and the message will confuse the author who hits it. All 10 current call sites are top-level in their function bodies (verified at main.go:5264, 6736, 7495, 9539, 13548, 13686, 16391, 17570, 17781, 23696), so the test passes today. Not a blocker; worth tightening the error text if you revisit.

Decision for the analytics owner — error events now send empty headline and raw_message. This affects every consumer of the error_seen PostHog board, not just this repo. The author's description already flags this: anything outside kaicontext/kai-cli that read those two fields will see empty values from the next release on. The kind grouping the board relies on is unaffected. This is the right privacy tradeoff, but it's a contract change to downstream analytics consumers that someone needs to sign off on.

The test TestReportSendsOnlyTheKind is a real behavioral test: it constructs an error whose err.Error() contains a sensitive path (/Users/someone/acme-payroll/src/salaries.go), sets Headline to text containing the same path, calls report(...), and asserts (a) the local errors.log does contain the secret and the kind, and (b) the captured telemetry call has empty headline/raw/ctx and that none of the sent fields contain "acme" or "salaries". If the fix were reverted (headline/LogContext forwarded again), assertion (b) fails immediately. The wiring test is also genuinely behavioral: reverting any command to defer te.Finish() removes the finishCommand defer, so isFinishDefer returns false and the test fails with a position-precise message. Both tests would fail on the unfixed code — they're not the discard-the-answer or skip-on-CI shapes that pretend to cover.

One note on the none/empty Kind guard at report_test.go:62-67: it asserts no telemetry call fires, and the early return at report.go:41 happens before LogLocal, so for Kind: "none" neither the local log nor telemetry fires — correct, and the test only asserts on the telemetry recorder for those cases, which is the point. No issue.

Ready to merge: yes, once the analytics owner signs off on emptying headline/raw_message for downstream consumers. The code is correct and the tests genuinely guard both fixes.

Findings

cmd/kai/telemetry_wiring_test.go:35 — parser.ParseDir(fset, ".", …) depends on the test's CWD being the package dir; a wrong CWD fails loudly via the len(seen) < 10 floor at line 92 (safe direction), but the test is CWD-sensitive by construction.

The test uses parser.ParseDir(fset, ".", …) which resolves the directory relative to the process working directory. Go's go test sets CWD to the package directory, so this works in practice and in CI, but a manually invoked test binary from a different directory would parse zero files and trip the len(seen) < 10 floor at line 92, failing loudly. The test cannot produce a false green from a wrong CWD.

internal/tui/errors/report.go:40 — the send parameter's inline function type couples this file to the unseen kai-engine ReportError signature; a build-time break only, acceptable for an injectable dependency.

The send parameter at report.go:40 uses an inline function type rather than a named type alias. A signature change to engine.ReportError (re-exported at api/telemetry/telemetry.go:8) would cause a compile-time break at this parameter and at the call site report.go:35, caught immediately by the build. This is the expected coupling for an injectable dependency.

Limitations

  • Could not read github.com/kaicontext/kai-engine/telemetry — ReportError and NewEvent are re-exports of functions defined in that sibling repo; the exact engine.ReportError signature is outside this boundary. However, the inline send parameter type in report.go and the record function in report_test.go both match the pre-existing call site's argument order, so the change compiles against the same signature.
  • Could not verify the PostHog error_seen board's grouping behavior — that is a property of an external analytics dashboard, not of this repository's code.
  • Did not run the tests in a Go toolchain (no review_shell available for Go); verification of the AST-parsing test's behavior on reverted code is based on reading the isFinishDefer logic, not execution.
  • Did not exhaustively read all 10 NewEvent call sites in cmd/kai/main.go — directly confirmed 3 (runInit, runPull, runShadowRun); the remaining 7 were confirmed via kai_grep output showing the same te := telemetry.NewEvent / defer func() { finishCommand(te, err) }() pattern, but their enclosing function signatures were not individually opened.

Decisions (need your call)

  • Error telemetry events now send empty headline and raw_message to PostHog, grouping on kind only; anything outside this repo that read those two fields would see empty values from the next release on — the analytics owner should confirm no external consumer joins on them (the error_seen board claim could not be verified from this repo).

the send parameter's inline function type couples this file to the unseen kai-engine ReportError signature; a build-time break only, acceptable for an injectable dependency.

The TUI's error view reported every classified error to PostHog with
the raw error string (raw_message) and the headline. The raw string is
err.Error(), which for a file error is the full path, home directory
and repo name included, and for a URL error the URL. The headline is
raw text on three rules as well. The error_seen board only ever reads
the kind, so both fields carried the riskiest content in the project
for no use.

Report now sends the kind, the severity and the auto-repair flag, and
nothing from the error itself. The raw string and headline stay in the
local errors.log, where they help. The telemetry call is a parameter
of an unexported report(), so the test drives it with a path in the
error and checks that none of it reaches the call while the local
errors.log still gets it, with no package state swapped.

Also pins the command wiring from #112 with a test that parses the
package: every telemetry.NewEvent call in a non-test file, however it
is written, must be the assignment of a string-literal event in a
top-level function's body, followed on the next statement by
`defer func() { finishCommand(<the event>, err) }()`, in a function
whose one result is the named `err error` that call reads. The
classifier tests could not see a command put back on
`defer te.Finish()`, which would report ok for every failure again.

Kai Summary

Nothing I'd call a defect, but 2 decisions to say yes to. 👇

Where I'd land: 4/5 — your call, then merge.

A correct, well-tested privacy fix that stops raw error text from reaching PostHog and structurally pins command telemetry wiring; merge once the analytics owner confirms no external reader depends on the two now-empty fields.

Decisions

Correct as written, but somebody should say yes to these:

  • Error telemetry events now carry empty headline, raw_message, and ctx. This affects any downstream consumer outside this repo that read those fields — they will see empty values from the next release on. The analytics owner should confirm no external dashboard, alert, or export depends on them being populated.
  • The same error-report change is claimed in kai-tui in a separate PR. If kai-tui has its own Report path that still forwards Headline or LogContext, the privacy fix is incomplete for errors surfaced through that binary. This is outside the boundary of this repo and could not be verified.

Review: kaicontext/kai-cli — "Stop sending raw error text to PostHog; pin command telemetry wiring"

Scope: I read all three changed files in full (internal/tui/errors/report.go, internal/tui/errors/report_test.go, cmd/kai/telemetry_wiring_test.go), the single caller of Report (internal/tui/views/repl.go:2079), the local-log writer (internal/tui/errors/log.go), the build-regression classifier rule (internal/tui/errors/classify.go:188), the finishCommand helper (cmd/kai/telemetry_result.go), the telemetry re-export (api/telemetry/telemetry.go), and all ten runX command bodies in cmd/kai/main.go. What I could NOT read: the external PostHog error_seen board, the sibling kai-tui PR, and the kai-engine/telemetry package itself (an import from another repo, not present in this workspace — so I could not directly open the ReportError definition, though the re-export at api/telemetry/telemetry.go:8 and the compile-time wiring confirm its signature is compatible).

What the change does, and my overall take: Report becomes a thin wrapper delegating to an unexported report that takes the telemetry send function as a parameter. report zeroes headline, raw_message, and ctx before calling send, so only kind, severity, and autoRepaired reach PostHog; LogLocal still receives the full UserError with Headline and LogContext intact. Separately, a new AST-parsing test walks cmd/kai's non-test files and enforces that every telemetry.NewEvent call is a top-level assignment of a string-literal event followed immediately by defer func() { finishCommand(<event>, err) }() in a function returning a named err error. The privacy fix is correct and verified by a test that would fail on the old code. The wiring test is genuinely structural. I found no defects.

Verification of the changed files

internal/tui/errors/report.go — The refactor is sound. Report (line 34) delegates to report passing telemetry.ReportError; the send parameter's type signature matches the argument order at lines 48–55 and matches the record closure in the test. The ue.Kind == "" || ue.Kind == "none" early return (line 41) fires before LogLocal, so nil/none classifications neither log nor telemetry — unchanged behavior, and the test at lines 71–76 asserts it. LogLocal (line 44) still receives the full ue, so errors.log retains Headline and LogContext (confirmed in log.go:85–86, which writes ue.Headline and ue.LogContext directly). The nil ctx at line 54 and the comment at lines 45–47 guard against a future whitelisted context being forwarded by default.

internal/tui/errors/report_test.go — This is a real test that would fail on the pre-change code. It constructs an error carrying /Users/someone/acme-payroll/src/salaries.go, runs both the fallback classifier and the gate.build_regression rule (whose Headline genuinely is the error's first line — confirmed at classify.go:193: Headline: strings.TrimSpace(head) where head is err.Error() before the first newline). It asserts none of acme/salaries reach the record callback (lines 55–58), that headline/raw/ctx are empty (line 52), and that errors.log still contains the secret at least twice and both kinds (line 66). On the pre-change code — which forwarded ue.Headline and ue.LogContext — the gate case would put secret into headline and the test would t.Fatalf at line 57. The fix is verified, not merely covered. The fallback's Headline is explicitly stuffed with the secret (line 37) after Classify, which deliberately tests that even a caller-constructed headline does not leak.

cmd/kai/telemetry_wiring_test.go — The test parses every non-test .go file in cmd/kai via parser.ParseDir with the filter at lines 35–37. The importName helper (lines 109–121) resolves the telemetry import name, handling aliases. The accepted map (line 52) is keyed by *ast.CallExpr pointer and populated during the f.Decls walk (lines 53–90) before the ast.Inspect sweep (lines 91–96) — so the ordering is correct: every top-level NewEvent assignment is marked accepted first, then the inspect flags any NewEvent call not in accepted (i.e., nested in a block, closure, or larger expression). The isFinishDefer helper (lines 155–179) precisely matches defer func() { finishCommand(v, err) }() and would reject defer te.Finish(), which is exactly the regression it guards. The floor at line 100 (len(seen) < 10) matches the ten command events I confirmed in main.go: init, capture, snapshot, ci_plan, status, diff, push, fetch, pull, shadow_run. code.go and do.go import telemetry but never call NewEvent, so neither the accepted loop nor the inspect sweep fires for them — correct.

Caller compatibility

The single caller, internal/tui/views/repl.go:2079, calls errpkg.Report(workspaceFor(r.services), ue, false) — the public three-arg signature, unchanged. No caller touches report directly (it's unexported). No signature break.

What's done well

  • The send parameter eliminates shared swappable state — no package variable, no race surface for parallel tests.
  • The privacy test exercises the riskiest real classifier rule (gate.build_regression, whose headline is raw error text), not a synthetic one.
  • The ctx-zeroing with an explicit "admit on purpose, not by default" comment is a good guard against a future context addition silently re-leaking.
  • The wiring test's "very next statement" rule (line 86) is the right invariant: anything between the event open and the defer could return early, leaving an unfinished event.

Decision for a human

The author flags this themselves: error_seen events now carry empty headline, raw_message, and ctx. Within this repo the board groups on kind only, so nothing here breaks. Anything outside this repo that read those two fields will see empty values from the next release on. This is a published telemetry-schema change; the analytics owner should confirm no downstream consumer — dashboards, alerts, or exports in a repo I cannot see — depends on headline or raw_message being populated. That confirmation lives outside this codebase; I could not verify it.

Sibling PR boundary

The description says the same change is made in kai-tui "in its own PR." I cannot see kai-tui from this workspace. If kai-tui has its own Report path that still forwards Headline or LogContext, the privacy fix is incomplete for errors surfaced through that binary. The fix is complete within kaicontext/kai-cli; I cannot confirm it for kai-tui.


Merge readiness: The code is sound — the privacy fix is correct and verified by a test that would fail on the old code, the wiring test is genuinely structural and passes on the current ten-command tree, and the single Report caller is unaffected by the refactor. The only thing requiring a human is the telemetry-schema decision (empty headline/raw_message), which the author has already framed for the analytics owner. That's a decision, not a defect, and doesn't block the merge. I'd merge it once the analytics owner confirms no external reader depends on the two now-empty fields.
