improve-agent SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

improve-agent from stempeck/agentfactory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add stempeck/agentfactory/improve-agent@git:20260916.8d1a006

Pins git:20260916.8d1a006 in mdr.lock. Pin the fingerprint instead.

Improve an agent's formula TOML based on post-execution learnings. Use after a formula run required manual intervention, produced incorrect artifacts, or left cleanup work for the operator. Classifies the failure type, scans for sibling vulnerabilities, selects the appropriate fix pattern, and surgically inserts corrective steps into the formula.

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

# Improve Agent Formula

Surgical improvement of a formula TOML based on observed execution failures or required manual intervention.

## Invocation

`/improve-agent <formula-path>` or `/improve-agent <agent-name>`

If agent-name given, resolve to `$AF_ROOT/.agentfactory/store/formulas/<agent-name>.formula.toml`.

## Phase 1: Gather Evidence

Collect what went wrong. Ask the user if not already clear from conversation context:

1. **What manual work was required after the formula ran?**
2. **Which files/paths were affected?**
3. **What was the expected state vs actual state?**

Record as a structured gap:

```
GAP: <one-line description>
EXPECTED: <what should have happened>
ACTUAL: <what happened instead>
MANUAL FIX: <what the operator had to do>
AFFECTED PATHS: <specific files/directories>
```

## Phase 1.5: Context Review

Phase 1 collects what the operator noticed. This phase collects what the run **measured** — the
per-step context figures the formula's own step records carry. Do it before reading the formula, so
Phase 2 already knows which steps are suspect.

1. **Find this run's instance.** Read `.runtime/improvement_pending` (relative to your own agent

How to install

The exact contents, by fingerprint

mdr add stempeck/agentfactory/improve-agent@sha256:e87b5455a36ceab0

The line at the top of this page pins the label git:20260916.8d1a006, 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.
