diagnose SKILL.md skillA
diagnose from itw-creative-works/workkit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Reproduce-first debugging, a red-capable repro before any hypothesis or edit. - Use when investigating a bug, a failing test, unexpected behavior, or a crash. Triggers on "diagnose", "debug this", "why is this failing", "not working", "broken", "repro", "root cause".
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: loop first, hypothesis second The iron rule: **build a feedback loop that shows the failure BEFORE you form a hypothesis or touch the code.** Guess-and-check edits without a repro destroy evidence and can't prove a fix. ## 1. Reproduce: the red-capable loop - Produce a command you can re-run that FAILS now because of this bug and will pass once it's fixed. - It can be a failing test (best: it becomes the §6 bug-fix test), a script, or a curl/CLI invocation. - Shrink it to the fastest reliable red. - Cannot reproduce? That IS the current task: instrument until you can. Never edit code "to see if it helps" before a repro exists. ## 2. Observe: tagged instrumentation - Add logging with a per-session tag: `[DEBUG-x7k2]` (any 4-char id). Tagged output is greppable in noisy logs and strippable in one sweep. - Log VALUES at boundaries (inputs, outputs, branches taken), not "got here". - Prefer widening observation over narrowing guesses. ## 3. Hypothesize: falsifiable, one at a time - State the hypothesis with its prediction BEFORE testing it: "If X is the cause, then changing/logging Y will show Z." …

How to install
mdr add itw-creative-works/workkit/diagnose@sha256:04facdd5141a00f1The line at the top of this page pins the label git:20261006.0e04d6f, 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.
