+# Execution Context
+
+## Project Patterns
+- Plugin naming: `agent-alchemy-{group-name}` for marketplace, `{group-name}` for directory
+- Reference files: H1 title, intro paragraph, structured sections with tables/code/bullets
+- Agent frontmatter: `name`, `description`, `model`, `tools`, `skills` in YAML + markdown system prompt
+- Phase-based workflows with "CRITICAL: Complete ALL N phases" directive
+- Hook scripts: trap ERR, debug function, jq parsing. All hooks must NEVER exit non-zero
+- Shared test fixtures: `claude/sdd-tools/tests/fixtures/`
+
+## Key Decisions
+- [Task #155] Structured context schema: 6 sections; compaction at 10+ entries
+- [Task #156] task-executor.md has embedded rules (414 lines); reference files documentation-only
+- [Task #161] Watch-first, poll-fallback completion detection
+- [Task #163] File conflict detection at Step 7a.5
+- [Task #164] produces_for injection uses `CONTEXT FROM COMPLETED DEPENDENCIES` header
+- [Task #166] 3-tier retry escalation: Standard → Context Enrichment → User Escalation
+- [Task #167] Progress streaming: session start, wave start, wave completion summaries
+- [Task #168] Post-merge validation: OK/WARN/ERROR; force compaction at >1000 lines
+- [Task #165] create-tasks now 9 phases; Phase 6 = producer-consumer detection
+- [Task #169] task-executor.md result file format is authoritative; orchestration.md needs updating
+
+## Known Issues
+- Result file format in orchestration.md (Result File Protocol + 7c prompt template) doesn't match task-executor.md. Non-blocking: validate-result.sh enforces correct format.
+- SKILL.md and orchestration.md step numbering diverge at Step 5/5.5
+- Concurrent edits to orchestration.md caused Edit conflicts in Wave 3a
+- hooks.json timeout field is in seconds, not milliseconds
+
+## File Map
+- `claude/sdd-tools/skills/execute-tasks/references/orchestration.md` — ~1223 lines
+- `claude/sdd-tools/agents/task-executor.md` — 414 lines with embedded rules
+- `claude/sdd-tools/skills/execute-tasks/references/execution-workflow.md` — 380 lines, documentation-only
+- `claude/sdd-tools/skills/execute-tasks/scripts/watch-for-results.sh` — Event-driven watcher
+- `claude/sdd-tools/skills/execute-tasks/scripts/poll-for-results.sh` — Adaptive polling (133 lines)
+- `claude/sdd-tools/hooks/validate-result.sh` — Result validation (~100 lines)
+- `claude/sdd-tools/skills/create-tasks/SKILL.md` — 9-phase workflow (~738 lines)

+## Features Implemented
+1. **Structured context schema** — 6-section schema for execution_context.md and per-task context files
+2. **Embedded agent rules** — task-executor.md has full execution workflow embedded (414 lines)
+3. **Event-driven completion** — watch-for-results.sh (fswatch) with poll-for-results.sh (adaptive) fallback
+4. **Result validation hook** — validate-result.sh PostToolUse hook with .invalid rename
+5. **File conflict detection** — Pre-wave scan in orchestration.md Step 7a.5
+6. **produces_for prompt injection** — Upstream task output injected into dependent task prompts
+7. **Retry escalation** — 3-tier: Standard → Context Enrichment → User Escalation
+8. **Progress streaming** — Session start, wave start, wave completion summaries
+9. **Post-wave merge validation** — OK/WARN/ERROR with auto-repair and force compaction
+10. **Bats test suite** — 44 tests across 3 scripts (19 + 14 + 11)
+
+## Known Issues
+- Result file format in orchestration.md (Result File Protocol + 7c prompt template) doesn't match task-executor.md embedded format. Non-blocking: validate-result.sh enforces correct format.
