What it does
Compound Docs is an agent skill from oliver-kriska/claude-elixir-phoenix. Searchable Elixir/Phoenix/Ecto solution documentation system with; Use when consulting past solutions…
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/resolution-template.md` and `references/schema.md`).
It sits in AI & LLM Engineering, covering LLM observability. It works with Elixir. 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
- Consulting past solutions…
- Tasks that involve LLM observability
Example prompts
- “/compound-docs”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.

- YAML frontmatter is MANDATORY — Every solution needs

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
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 Docs loads about 528 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 121 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.

problem_type: runtime_error
component: ecto_schema
symptoms:
- "Ecto.Association.NotLoaded on user.posts"
root_cause: missing_preload
severity: medium

# Association NotLoaded on User Posts
## Symptoms
Ecto.Association.NotLoaded raised when accessing user.posts
in UserListLive after filtering.
## Root Cause
Query in Accounts context missing preload for :posts.
## Solution
Added `Repo.preload(:posts)` to `list_users/1`.
## Prevention
Use n1-check skill before shipping list views.Searching Solutions
Use Grep to search .claude/solutions/ by symptom (e.g., NotLoaded), by tag (e.g., tags:.*preload), or by component (e.g., component: ecto).
