description: Searchable solution documentation system with YAML frontmatter. Builds institutional knowledge from solved problems. Use proactively when consulting past solutions before investigating new issues.

Compound Docs — Institutional Knowledge Base

Searchable, categorized solution documentation that makes each debugging session easier than the last.

Iron Laws

  1. •ALWAYS search solutions before investigating — Check .claude/solutions/ for existing fixes before debugging
  2. •YAML frontmatter is MANDATORY — Every solution needs validated metadata per references/schema.md
  3. •One problem per file — Never combine multiple solutions
  4. •Include prevention — Every solution documents how to prevent recurrence

Solution File Format

module: "Accounts"
date: "2025-12-01"
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

bash
# Search by symptom
grep -rl "NotLoaded" .claude/solutions/
# Search by tag
grep -rl "tags:.*preload" .claude/solutions/
# Search by component
grep -rl "component: ecto" .claude/solutions/
