What it does
Compound is an agent skill from oliver-kriska/claude-elixir-phoenix. Capture solved problems as searchable solution docs. Use after fixing bugs, when "that worked", or after successful /phx:review or /phx:investigate.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/compound-workflow.md`).
It sits in Security. The repository describes itself as: Claude Code plugin for Elixir/Phoenix/LiveView — 26 specialist agents, Iron Laws enforcement, and Tidewave MCP integration. Plan features with parallel research agents, execute… The licence is MIT.
When your agent uses it
- Security work in your project
Example prompts
- “that worked”
- “/compound”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 9767a82. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Compound loads about 964 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 392 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 contextPhilosophy
Each unit of engineering work should make subsequent units easier — not harder.
Workflow
Step 1: Detect Context
- If
$ARGUMENTSprovided, use as description - If no args, check scratchpad DEAD-END/DECISION entries,
git diff,.claude/plans/{slug}/progress.mdfor recent completions - 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 steps, root cause, solution code, and prevention advice.
Validate frontmatter against ${CLAUDE_PLUGIN_ROOT}/skills/compound-docs/references/schema.md,
then create file using ${CLAUDE_PLUGIN_ROOT}/skills/compound-docs/references/resolution-template.md.
Write-blocked fallback: if writing to .claude/solutions/ is denied
by permissions, do NOT silently drop the solution. Output the full
solution doc inline (fenced markdown the user can paste), then suggest
/phx:permissions to allow .claude/solutions/ writes for next time.
Step 4: Decision Menu
- Continue (default)
- Promote to Iron Law check — Add to iron-law-judge
- Update skill reference — Add to relevant skill
- Update CLAUDE.md — Add prevention rule
Auto-Trigger Phrases
When user says "that worked", "it's fixed", "problem solved",
"the fix was" — suggest /phx:compound.
Show full SKILL.md (164 more words)Show less
Supply-chain finding auto-feed (Phase 3)
When /phx:deps-audit produces a BLOCK-severity finding that the
user investigates and confirms is a real malicious pattern (not a
false positive), suggest:
Caught a high-severity finding in
<pkg>@<version>. Run/phx:compoundto capture this for future audits?
If accepted, the resulting solution doc goes to
.claude/solutions/supply-chain/<pkg>-<cve_or_pattern>.md and
includes the exact rule-id + snippet + diff window that triggered
the finding. This compounds the audit corpus: future runs of
/phx:deps-audit grep solutions/supply-chain/ for snippet
matches and pre-elevate severity on known-bad patterns.
Always prompt; never auto-write. Solution docs are durable and shape future trust calls — the user reviews before committing.
Iron Laws
- YAML frontmatter validates or STOP
- Symptoms must be specific — not "it broke"
- Root cause is WHY, not WHAT
- One problem per file
- NEVER document a fix before verifying it works — run
mix compile && mix testfirst; unverified solutions poison the knowledge base
