What problem does it solve? Projects accumulate quirks—custom integration wiring, environment constraints, tooling gotchas—that agents rediscover the hard way every session. This Skill captures those confirmed deviations once in a per-project note so future work starts with the facts already loaded instead of re-debugging the same surprises. ## Core Features & Use Cases - Per-project deviation notes: Stores one <project>-deviations.md file per project in the shared skill-data directory (${XDG_CONFIG_HOME:-$HOME/.config}/tsch-ai-skills/), outside the skill install directory so updates never overwrite them. - Load-before-work workflow: Checks for and reads the matching note before investigating project-specific behavior, preventing wrong assumptions. - Evidence-based recording: Only confirmed deviations are written, stated as current facts without investigation narratives, changelogs, or debugging history. - Use Case: A repo's make test writes into /tmp and fails when TMPDIR points at a mounted volume. Record it once; the next session loads the note before running tests and avoids the failure. ## Quick Start Check whether a deviations note exists for this project and load it before debugging, then record any confirmed environment quirk you discover.
