What problem does it solve? Long-running or unattended work leaves reviewers unable to reconstruct what was decided, why, and on what evidence without rereading entire transcripts. This Skill keeps a single canonical decision trail so a human can audit the run after the fact. ## Core Features & Use Cases - Structured TSV decision log: One row per decision with timestamp, phase, decision, rationale, evidence pointer, and result, rendered as a sortable table on GitHub or in a terminal. - Safe logging helper: The scripts/log.sh script appends well-formed rows, strips stray tabs and newlines, and neutralizes spreadsheet formula injection from untrusted cell content. - End-of-run audit and cross-model review: Verifies the log against the actual transcript and spawns a subagent on a different model family to flag weak evidence, skipped verification, and risky choices. - Use Case: During a multi-week migration, an agent logs each fork, revert, and verification result to decisions.tsv; a reviewer later opens the committed file in the PR and follows each evidence link to trust the outcome. ## Quick Start Ask the agent to keep a show-me-your-work decision log for this task and append a row for each major decision with its evidence and result.
