solo-diagnose from fortunto2/solo-factory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add fortunto2/solo-factory/solo-diagnose@v1.0.0

Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Diagnosis loop for hard bugs and performance regressions — build a tight feedback loop first, hypothesise second. Use when user says "diagnose", "debug this", "why is this broken", "почему падает", "тормозит", or reports something throwing, failing, flaky, or slow. Do NOT use for code quality review (/review) or feature planning (/plan).

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

# /diagnose — the feedback loop is the skill

A discipline for hard bugs. Skip a phase only with an explicit reason.

Before exploring, read the project `CLAUDE.md` and any `CONTEXT.md` for the module vocabulary, and check ADRs in the area you're touching.

## Phase 1 — Build a feedback loop

**This is the skill.** Everything else is mechanical. With a **tight** pass/fail signal that goes red on _this_ bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume it. Without one, no amount of staring at code saves you.

Spend disproportionate effort here. Be aggressive, be creative, refuse to give up.

### Ways to construct one — roughly in this order

1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.
2. **Curl / HTTP script** against a running dev server.
3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.
4. **Headless browser script** (Playwright MCP or a script) — drives the UI, asserts on DOM/console/network.
5. **Replay a captured trace.** Save a real request / payload / event log to disk; replay it through the code path in isolation.

How to install

The exact contents, by fingerprint
mdr add fortunto2/solo-factory/solo-diagnose@sha256:227211690effb8b4

The line at the top of this page pins the label v1.0.0, 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.
