 A spec flows through three stages, one per `internal/` package:
 
-1. **parse** (`internal/parser`) — load and validate the spec with libopenapi, resolve `$ref`s.
-2. **analyze** (`internal/analyzer`) — lower the spec into the intermediate representation (`internal/ir`): operations, params, types, pagination. This is where naming, disambiguation, and pagination detection happen.
-3. **generate** (`internal/generator`) — render the IR through `text/template` files (`internal/templates/*.tmpl`, embedded via `embed.go`) and post-process each file with `goimports` (`WriteFiles`).

+Applies to commit messages, PR and issue text, code comments, and docs.
+- No em dashes or en dashes. Use a comma, colon, parenthesis, or a second sentence.
+- This repo has one maintainer. Say what changed and why. Leave out reviewer-facing hedging: apologies for scope, offers to reorganize a PR for someone else, anything addressed to a team that isn't there.
 
 ### Comments
 Default to writing no comments. Only add one when the WHY is non-obvious: a hidden constraint, a subtle invariant, a workaround for a specific bug, behavior that would surprise a reader. If removing the comment wouldn't confuse a future reader, don't write it. Specifically avoid:
-- WHAT comments. Names and code already say what — `// hasRequiredQueryParams returns whether there are required query params` above a function of that name is noise.

 - Conventions that hold across the package (e.g. "wire names use OrigName" is true everywhere, so don't repeat it on each helper).
-- References to current task / fix / callers (`// so foo_test.go can exercise this`, `// matching how auth cookies are built`, `// added for the X flow`) — they rot. Such context belongs in the PR description.
-- Multi-paragraph docstrings. One short line max — if you need more, the function is doing too much.

 ### DRY
 When the same logic appears in multiple places, extract a shared helper. Before writing new code, check whether an existing helper already does it. When adding encoding/naming/forwarding that mirrors existing code, reuse it rather than duplicating.

 ### Testing
-- **Test real code.** Tests import and call the actual functions under test — never reimplement the logic being tested. For the generator, the strongest tests generate a client from a spec and then compile/run it (`internal/generator/e2e_test.go`), so a broken template fails the test rather than a restated assertion.

 - Prefer `t.Context()` over `context.Background()` in tests.
 - When changing a template, add or extend an e2e test that compiles the affected operation shape.
