File contents

When this fires

Project or milestone completion. User wants to distill what was learned, what patterns emerged, what to reuse. Writes docs/matilha/den/<date>-<topic>.md.

Preconditions

project-status.md exists.
At least one wave completed.

Execution Workflow

Read completed waves from project-status.md via Read tool.
Prompt user for topic (e.g., "auth system patterns").
Read relevant wave outputs (commits via Bash, spec/plan/review_report via Read) for the topic.
Synthesize via Write into docs/matilha/den/<date>-<topic>.md with sections: context, patterns observed, decisions + why, would-do-differently.
Update project-status.md recent_decisions with pointer to the den file.

Rules: Do

Cite specific commits + files in findings.
Include "would-do-differently" section (honest retrospective).
Timestamp the filename.

Rules: Don't

Delete existing den files (keep history).
Write generic advice (be specific to THIS project).

Expected Behavior

Knowledge captured in navigable markdown that informs future /matilha-pack packaging.

Quality Gates

Den file exists at docs/matilha/den/<date>-<topic>.md.
Cited commits are real (verifiable via git log).

Companion Integration

No companion integrations in Wave 4a.

Output Artifacts

docs/matilha/den/<date>-<topic>.md.

Example Constraint Language

Use "must" for: cite wave(s) being distilled.
Use "should" for: include would-do-differently.
Use "may" for: split across multiple files for a large project.

Troubleshooting

"no waves completed": Run /matilha-gather first.
"topic too broad": Split into multiple den files per sub-topic.

CLI shortcut (optional)

matilha den <topic> (future CLI command; not shipped yet).
