fa-self-improve SKILL.md skillA
fa-self-improve from istin/flutter_agent_harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

When a live session exposes an FA harness limitation or design gap (an agent failure caused by a MECHANISM — compaction burying instructions, a gate masking another, a watch tripping on stray edits), turn it into a harness-improvement goal card end-to-end — root-cause the mechanism in code, draft via the create-goal discipline THROUGH a subagent, file the issue with gh, enforce WIP status, and HARD-VERIFY the subagent's output. Use when the user says the harness itself must be fixed so a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FA Self-Improve — session findings → harness improvement cards This skill encodes the workflow proven on the 2026-10-08 night incident (skills' operative lines dying in compaction folds → card #1409): a live session is the best harness test suite there is, but only if its failures are converted into durable, correction-proof cards instead of war stories. The dividing line for using this skill: **the failure must belong to FA, not to the agent's judgment.** "The model ignored an instruction" is not a harness bug — "the instruction was physically removed from context by compaction" is. When the mechanism, not the discipline, failed, file a card. ## Workflow (five steps, each with an exit condition) ### 1. Define the problem as a MECHANISM, not a symptom Write one sentence of the form: *"<input state> causes <mechanism> so <observable failure>, and <what amplified it>."* If you cannot name the mechanism, you have a symptom — go to step 2 before writing anything. Include the amplification path. Incidents stick through self-precedent: hours of successful execution with the wrong behavior outweigh a lost instruction. State plainly WHY the failure survived as long as it did …

How to install
mdr add istin/flutter_agent_harness/fa-self-improve@sha256:e8522f3904083c67The line at the top of this page pins the label git:20261008.565e37b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
