Context Manager Task 3 Implementer Report

Status

• Done
• Implemented heuristic transcript-slice extraction in .pi/agent/extensions/context-manager/src/extract.ts
• Added focused tests in .pi/agent/extensions/context-manager/src/extract.test.ts

Changes

• Added TranscriptSlice and extractCandidates().
• Reused MemoryCandidate, MemoryScope, and MemorySourceType from src/ledger.ts.
• Added heuristics for:
  • user goal extraction
  • role-aware constraint extraction
  • decision extraction
  • next-step / task extraction
  • file reference extraction
• Kept constraint extraction from duplicating structured Goal:, Decision:, and Next: lines so the output matches the requested candidate set.

Tests

• Verified red state first:
  • cd .pi/agent/extensions/context-manager && npx tsx --test src/extract.test.ts
  • Result: failed with ERR_MODULE_NOT_FOUND because src/extract.ts did not exist
• Verified green state after implementation:
  • cd .pi/agent/extensions/context-manager && npx tsx --test src/extract.test.ts
• Ran full extension test suite:
  • cd .pi/agent/extensions/context-manager && npm test

Files Changed

• Created .pi/agent/extensions/context-manager/src/extract.ts
• Created .pi/agent/extensions/context-manager/src/extract.test.ts
• Created .pi/reviews/context-manager-task3-implementer-report.md

Self-Review Findings

• The implementation is tightly scoped to extraction only.
• Test coverage matches the task requirements and verifies both user and non-user sources.
• File reference extraction is intentionally heuristic and limited to the requested extensions.

Concerns

• The provided implementation snippet would also classify Decision: ... avoid ... as a constraint; I prevented that duplicate extraction so the required tests pass.
• No other concerns.
