+# ECC Guide
+
+Use this skill when a user needs help understanding, navigating, installing, or choosing parts of Everything Claude Code.
+
+## When To Use
+
+Use this skill when the user:
+
+- asks what ECC includes
+- wants help finding a skill, command, agent, hook, rule, or install profile
+- is new to the repository and needs a guided path
+- asks "how do I do X with ECC?"
+- asks which ECC components fit a project
+- needs a lightweight explanation of how commands, skills, agents, hooks, and rules relate
+- is confused by install paths, duplicate installs, reset/uninstall, or selective install options
+
+## Core Principle
+
+Answer from current files, not memory. ECC changes quickly, so hard-coded catalog counts, feature lists, and install instructions go stale.
+
+When the ECC repository is available, inspect the relevant files before giving a concrete answer:
+
+```bash
+node scripts/ci/catalog.js --json
+find skills -maxdepth 2 -name SKILL.md | sort
+find commands -maxdepth 1 -name '*.md' | sort
+find agents -maxdepth 1 -name '*.md' | sort
+node scripts/install-plan.js --list-profiles
+node scripts/install-plan.js --list-components --json
+```
+
+Use the smallest set of reads needed for the user's question.
+
+## Repository Map
+
+- `README.md`: install paths, uninstall/reset guidance, public positioning, FAQs
+- `AGENTS.md`: contributor guidance and project structure
+- `agent.yaml`: exported gitagent surface and command list
+- `commands/`: maintained slash-command compatibility shims
+- `skills/*/SKILL.md`: reusable workflows and domain playbooks
+- `agents/*.md`: delegated subagent role prompts
+- `rules/`: language and harness rules
+- `hooks/README.md`, `hooks/hooks.json`, `scripts/hooks/`: hook behavior and safety gates
+- `manifests/install-*.json`: selective install modules, components, profiles, and target support
+- `docs/`: harness guides, architecture notes, translated docs, release docs
+
+## Response Style
+
+Lead with the answer, then give the next action. Most users do not need a full catalog dump.
+
+Good first response shape:
+
+1. what to use
+2. why it fits
+3. exact file or command to inspect
+4. one next command or question
+
+Avoid:
+
+- listing every skill or command by default
+- repeating large README sections
+- recommending retired command shims when a skill-first path exists
+- claiming a component exists without checking the filesystem
+- replacing install guidance with manual copy commands when the managed installer supports the target
+
+## Common Tasks
+
+### New User Onboarding
+
+Give a short menu:
+
+- install or reset ECC
+- pick skills for a project
+- understand commands vs skills
+- inspect hooks and safety behavior
+- run a harness audit
+- find a specific workflow
+
+Point to `README.md` for install/reset and `/project-init` for project-specific onboarding.
+
+### Feature Discovery
+
+For "what should I use for X?":
+
+1. Search `skills/`, `commands/`, and `agents/`.
+2. Prefer skills as the primary workflow surface.
+3. Use commands only when they are a maintained compatibility shim or a user explicitly wants slash-command behavior.
+4. Mention agents when delegation is useful.
+
+Useful searches:
+
+```bash
+rg -n "<query>" skills commands agents docs
+find skills -maxdepth 2 -name SKILL.md | sort
+```
+
+### Install Guidance
+
+Use managed install paths:
+
+```bash
+node scripts/install-plan.js --list-profiles
+node scripts/install-plan.js --profile minimal --target claude --json
+node scripts/install-apply.js --profile minimal --target claude --dry-run
+```
+
+For specific skill installs:
+
+```bash
+node scripts/install-plan.js --skills <skill-id> --target claude --json
+node scripts/install-apply.js --skills <skill-id> --target claude --dry-run
+```
+
+Warn users not to stack plugin installs and full manual/profile installs unless they intentionally want duplicate surfaces.
+
+### Project Onboarding
+
+Use `/project-init` when the user wants ECC configured for a target repo. The expected sequence is:
+
+1. detect the stack from project files
+2. resolve a dry-run install plan
+3. inspect existing `CLAUDE.md` and settings files
+4. ask before applying changes
+5. keep generated guidance minimal and repo-specific
+
+### Troubleshooting
+
+Ask for the target harness and install path first, then inspect:
+
+- plugin install metadata
+- `.claude/`, `.cursor/`, `.codex/`, `.gemini/`, `.opencode/`, `.codebuddy/`, `.joycode/`, or `.qwen/`
+- `hooks/hooks.json`
+- install-state files
+- relevant command/skill files
+
+For repo health, suggest:
+
+```bash
+npm run harness:audit -- --format text
+npm run observability:ready
+npm test
+```
+
+## Output Templates
+
+### Short Recommendation
+
+```text
+Use <skill-or-command>. It fits because <reason>.
+
+Canonical file: <path>
+Verify with: <command>
+Next: <one concrete action>
+```
+
+### Search Results
+
+```text
+Best matches:
+- <path>: <why it matters>
+- <path>: <why it matters>
+
+Recommendation: <which one to use first and why>
+```
+
+### Install Plan Summary
+
+```text
+Detected: <stack evidence>
+Target: <harness>
+Plan: <profile/modules/skills>
+Dry run: <command>
+Would change: <paths>
+Needs approval before apply: <yes/no>
+```
