shellbrain SKILL.md skillA

shellbrain from cucupac/shellbrain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cucupac/shellbrain/shellbrain@git:20260924.aacf66b

Pins git:20260924.aacf66b in mdr.lock. Pin the fingerprint instead.

Recall project knowledge, past decisions, failures, and preferences when they can help a coding task. Capture changed files before responding.

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

# Shellbrain Recall Workflow

Use Shellbrain for remembered project knowledge. It can explain a system's purpose,
past decisions, useful fixes, and constraints learned during earlier work.

## Choose the source

Use code search for current implementation: where a function lives, its parameters,
callers, or present behavior. Use docs or the web for general technical information.
Recall helps with project context that may be missing from those sources.

| Need | Action |
| --- | --- |
| Find the quote endpoint | Search the repo. |
| Understand a previous quote failure | Ask: "What past failures explain a quote returning 503 while the Swap API health check succeeds?" |
| Prepare to change discovery | Ask: "What earlier problems or design decisions matter when changing the discovery-to-optimization handoff in compute_route?" |
| Get project orientation | Ask about the named system's remembered purpose and responsibilities, then check current code. |

A normal question is enough. Include the subject, your task or symptom, and what you need to learn.
Do not invent a prior failure or guess the answer to make a query specific.

How to install

The exact contents, by fingerprint

mdr add cucupac/shellbrain/shellbrain@sha256:4ba95be6e4e5ba97

The line at the top of this page pins the label git:20260924.aacf66b, 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.
