From 363688bf0c467e6126e501f7544b18aaea97c0f2 Mon Sep 17 00:00:00 2001 From: Lakshman Patel Date: Wed, 5 Aug 2026 15:34:12 +0530 Subject: [PATCH 01/11] feat(spec): add proposal and design stages, parallel workflow, enhanced hooks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add Proposal and Design stages to the spec workflow so Specify and Design can run in parallel after Proposal, then converge for Plan → Tasks → Implementing. Implement command hook loading from .md frontmatter, fsnotify bridge for file_changed events, and real built-in hook implementations. --- cmd/chat_subcommand_spec.go | 4 +- cmd/chat_update.go | 4 +- cmd/spec_picker.go | 8 +- internal/engine/permission_session_methods.go | 18 +- internal/engine/safety/permission_engine.go | 36 ++-- .../engine/safety/permission_engine_test.go | 9 +- internal/engine/safety/spec_workflow.go | 50 +++++- internal/engine/safety/spec_workflow_test.go | 32 +++- internal/engine/safety_reexports.go | 2 + internal/hooks/file_watcher.go | 120 +++++++++++++ internal/hooks/hooks.go | 163 +++++++++++++++--- internal/spec/state.go | 26 ++- internal/tool/spec.go | 138 ++++++++++++--- 13 files changed, 517 insertions(+), 93 deletions(-) create mode 100644 internal/hooks/file_watcher.go diff --git a/cmd/chat_subcommand_spec.go b/cmd/chat_subcommand_spec.go index 5fc55487..7f2f2efe 100644 --- a/cmd/chat_subcommand_spec.go +++ b/cmd/chat_subcommand_spec.go @@ -55,8 +55,8 @@ func (s *specSubcommand) Handle(m *chatModel, args []string, text string) (tea.M return handleSpecConfig(m, arg) } - m.session.PermSvc().SetSpecStage(engine.SpecStageSpecify) - m.messages = append(m.messages, displayMsg{role: "system", content: "Spec workflow started — Write/Edit/Bash are gated until spec.md, plan.md, and tasks.md are written and ApproveImplementation is approved."}) + m.session.PermSvc().SetSpecStage(engine.SpecStageProposal) + m.messages = append(m.messages, displayMsg{role: "system", content: "Spec workflow started — Write/Edit/Bash are gated.

Phase gates (Simplicity, Anti-Abstraction, Integration-First) checked at Plan. Constitution injected into system prompt at all spec stages. Phase 2: EARS notation validation (The system shall, WHEN...THEN, SHALL NOT). REQ-XXX.Y.Z requirement IDs with extraction from spec and code. Orphan REQ detection (code cites REQ not in spec = hallucination). Missing REQ detection (REQ in spec not in code = gap). Phase 3: NEEDS CLARIFICATION enforcement (max 3, blocks Plan if unresolved). Phase 4: Hallucination detection via inline citations. ScanCodeForReqIDs scans source files for [REQ-XXX] comments. FindOrphanReqIDs and FindMissingReqIDs in spec validator. Phase 5: Task dependency analysis and parallel group identification. ParseTasks extracts file refs, REQ IDs, and dependencies. AnalyzeTaskGroups identifies parallel-safe vs sequential tasks. Phase 6: Auto convergence with REQ coverage checks. ConvergeTool now detects orphan and missing REQs. Phase 7: Enhanced file-watcher with source/test file detection. --- SPEC_DRIVEN_PLAN.md | 124 +++++++++++ cmd/spec_picker_test.go | 4 +- internal/engine/permission_session_methods.go | 40 +++- internal/engine/safety/permission_engine.go | 93 +++++++- .../engine/safety/permission_engine_test.go | 17 +- internal/engine/spec_mode_test.go | 50 ++++- internal/engine/stream.go | 4 + internal/hooks/file_watcher.go | 19 +- internal/spec/tasks.go | 203 ++++++++++++++++++ internal/spec/validator.go | 148 +++++++++++++ internal/tool/spec.go | 2 +- internal/tool/spec_analyze.go | 38 ++++ internal/tool/spec_constitution.go | 114 ++++++++-- internal/tool/spec_converge.go | 34 ++- 14 files changed, 838 insertions(+), 52 deletions(-) create mode 100644 SPEC_DRIVEN_PLAN.md create mode 100644 internal/spec/tasks.go diff --git a/SPEC_DRIVEN_PLAN.md b/SPEC_DRIVEN_PLAN.md new file mode 100644 index 00000000..a21c5f0b --- /dev/null +++ b/SPEC_DRIVEN_PLAN.md @@ -0,0 +1,124 @@ +# Spec-Driven Workflow — Complete Implementation Plan + +## Current State (After Initial Implementation) +- Proposal → Specify + Design (parallel) → Plan → Tasks → Implementing +- Constitution tool exists but is optional +- Cross-artifact validation exists (AnalyzeTool) +- Convergence tool exists but is manual +- File-watch hooks bridge exists +- Command hooks with patterns exist + +## Target State (Perfect Spec-Driven Workflow) + +### Phase 1: Constitution as Enforced Guardrails +**Goal:** Constitution is REQUIRED before spec work begins.
