Capture solved problems as searchable solution docs. Use after fixing bugs, when "that worked", or after successful /phx:review or /phx:investigate.
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
# Compound — Capture Solutions as Knowledge
After fixing a problem, capture the solution as searchable
institutional documentation.
## Usage
```
/phx:compound Fixed N+1 query in user listing
/phx:compound Resolved LiveView timeout in dashboard
/phx:compound # Auto-detects from recent session context
```
## Philosophy
> Each unit of engineering work should make subsequent units
> easier — not harder.
## Workflow
### Step 1: Detect Context
1. If `$ARGUMENTS` provided, use as description
2. If no args, check scratchpad DEAD-END/DECISION entries,
`git diff`, `.claude/plans/{slug}/progress.md` for recent completions
3. If unclear, ask: "What problem did you just solve?"
**Only document non-trivial problems** that required investigation.
### Step 2: Search Existing Solutions
Create `.claude/solutions/` directory if it doesn't exist (run `mkdir -p .claude/solutions`).
Then search `.claude/solutions/` for relevant keywords using Grep.
If found: **Create new** (different root cause), **Update
existing** (same root cause, new symptom), or **Skip**.
### Step 3: Gather Details and Create Solution
Extract from session context: module, symptoms, investigation

How to install
mdr add oliver-kriska/claude-elixir-phoenix/compound@sha256:9c047e6f584dfd71The line at the top of this page pins the label git:20260724.918f809, 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.
