Agent Implementation Notes — Running Log

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

Purpose

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.

When to invoke

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

• Implements behavior whose spec has known ambiguity (e.g., // UNCONFIRMED markers, "Unconfirmed ?" prerequisites).
• Introduces a new dependency, target, or module.
• Refactors existing code beyond a one-line fix.
• Any M- or L-size task by your workflow's task-sizing convention, if it has one (touches ≥2 files, adds new behavior, or gets a spec/plan before code).

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