name: agent-impl-notes-log\ndescription: \"Keep a running impl-notes file next to the phase meeting log while a subagent executes a task, recording design decisions, intentional deviations from spec, tradeoffs, and open questions as they happen rather than after the fact. Use at the start of any non-trivial subagent dispatch (multi-file change, ambiguous spec, new dependency or module, refactor), when ambiguity is hit mid-task, or before deviating from spec. Not the post-hoc meeting log (session-to-meeting-log); the two coexist.\"\nargument-hint: \"[topic]\"

Agent Implementation Notes — Running Log

\n

Invoke with a topic argument (frontmatter argument-hint: \"[topic]\").

\n

Purpose

\n

The phase meeting log (meetings/{date}_{topic}.md) is summative — written after work completes. By that point, dozens of micro-decisions made mid-flight are already lost to the commit diff. An impl-notes log fills that gap: a concurrent record of decisions, deviations, tradeoffs, and unresolved questions, written as they happen.

\n

When to invoke

\n

Subagent MUST invoke this skill at the start of any dispatch matching ANY of:

\n\n

Subagent MAY skip this skill for trivial one-line fixes, pure typo corrections, or documentation copy edits.

\n

File layout

\n

Path: meetings/{YYYY-MM-DD}_{topic}.impl-notes.md

\n

Paired naming with the phase meeting log. If the phase log is meetings/2026-05-20_phase-11-foo.md, the impl-notes is meetings/2026-05-20_phase-11-foo.impl-notes.md.

\n

If multiple subagents work on the same topic on the same day, append a numeric suffix: meetings/2026-05-20_topic.impl-notes.2.md.

\n

File format

\n
# Impl Notes — {topic} ({date})\n\nStatus: IN_PROGRESS\nOwner: {subagent type, e.g. \"Senior Developer\"}\nDispatched by: Leader\nStarted: {ISO timestamp}\n\n## 設計決定 (Design decisions)\n\n_What you chose when the spec was ambiguous. Include the spec reference._\n\n- **{decision name}** — Spec `docs/design.md §X.Y` says \"...\". Ambiguous on Z. Chose **A** because [reason]. Alternative was B (see §折衷).\n\n## 偏離 (Deviations)\n\n_Intentional deviations from the documented spec. Include the spec reference and the why._\n\n- **{deviation name}** — Spec says X. Implemented as Y because [reason]. Downstream impact: [what changes for callers / tests / docs].\n\n## 折衷 (Tradeoffs)\n\n_Alternatives considered and the reasoning for the current pick._\n\n- **{tradeoff topic}** — Considered: [A, B, C]. Picked **B** because [reason]. Rejected A because [reason]; rejected C because [reason].\n\n## 未決 (Open questions)\n\n_Things you want Leader / User to confirm. Be specific. Block on these before final report if they're load-bearing._\n\n- **{question}** — [specific question]. Default behavior I picked: [X]. Risk if I'm wrong: [impact].\n

How to update

\n\n

Status transitions

\n\n

Subagent dispatch contract (Leader-side)

\n

When Leader dispatches a subagent matching the invoke criteria, the dispatch prompt MUST include:

\n
\n

Create meetings/{date}_{topic}.impl-notes.md at the start of your work using the collaboration-skills:agent-impl-notes-log skill format (or have it preloaded via the agent definition's skills: field). Update it incrementally — design decisions, deviations, tradeoffs, open questions. Mark Status: COMPLETE before final report. Include the file path in your report.

\n
\n

Subagent's final report MUST link the impl-notes file. Leader reads it before merging the work to verify decisions match Leader's intent.
