brewcode:setup

Phase 0: Prerequisites Check

Agent: developer | Action: Verify and install required tools

Context: This phase auto-checks prerequisites. If all required components are present, it skips to Phase 1 silently.

Step 1: State Check

EXECUTE using Bash tool:

bash "${CLAUDE_SKILL_DIR}/scripts/install.sh" state && echo "✅ state" || echo "❌ state FAILED"

STOP if ❌ — verify install.sh exists in scripts/.

Step 2: Evaluate Results

Parse the state output table. Check required components: brew, timeout, jq.

• If ALL required show ✅ → Skip to Phase 1 (log: "All prerequisites present, skipping installation.")
• If ANY required show ❌ missing → Continue to Step 3

Step 3: Install Required Components

EXECUTE using Bash tool:

bash "${CLAUDE_SKILL_DIR}/scripts/install.sh" check-timeout && echo "✅ timeout-check" || echo "❌ timeout-check FAILED"

If TIMEOUT_EXISTS=false → ASK (AskUserQuestion):

• Question: "The timeout command is missing. Create symlink to gtimeout? This is REQUIRED for brewcode."
• Options: "Yes, create" | "Cancel setup"

If cancel → STOP: "Setup cancelled. timeout command is required for brewcode."

EXECUTE using Bash tool:

bash "${CLAUDE_SKILL_DIR}/scripts/install.sh" required && echo "✅ required" || echo "❌ required FAILED"

STOP if ❌ — required components must be installed before continuing.

If timeout still missing → EXECUTE: bash "${CLAUDE_SKILL_DIR}/scripts/install.sh" timeout

Step 4: Semantic Search (Optional)

If grepai not installed → ASK (AskUserQuestion):

• Question: "Install semantic search (grepai)? Enables AI-powered code search (~1.5GB)."
• Options: "Yes, install grepai" | "Skip"

If Yes → EXECUTE: bash "${CLAUDE_SKILL_DIR}/scripts/install.sh" grepai

Step 5: Summary

EXECUTE using Bash tool:

bash "${CLAUDE_SKILL_DIR}/scripts/install.sh" summary && echo "✅ summary" || echo "❌ summary FAILED"

Phase 1: Project Structure Analysis

Agent: Explore | Action: Scan project and gather intelligence

Context: BC_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).

Scan Commands

EXECUTE using Bash tool — gather project info:

bash "scripts/setup.sh" scan && echo "✅ scan" || echo "❌ scan FAILED"

STOP if ❌ — check script exists and plugin is installed.

---

Phase 3: Template Generation

Agent: developer | Action: Generate adapted template at .claude/tasks/templates/PLAN.md.template

Create Structure

EXECUTE using Bash tool:

bash "scripts/setup.sh" structure && echo "✅ structure" || echo "❌ structure FAILED"

STOP if ❌ — verify .claude/tasks directory is writable.

Copy/Update Templates

EXECUTE using Bash tool — sync templates from plugin (always overwrites if changed):

bash "scripts/setup.sh" sync && echo "✅ sync" || echo "❌ sync FAILED"

STOP if ❌ — verify plugin templates exist.

Note: Templates synced from plugin. Rules created once (never overwritten). Review skill adapted by AI.

Template Modifications

Section	Adaptation
Agents	Add project-specific agents from .claude/agents/
Reference Examples	Fill with project's reference files (controllers, services, tests)
Phase V agents	Customize reviewer focus for detected testing/code patterns
Final Review	Add project agents (db_expert, etc.) if relevant tech detected

Required Sections

Preserve universal structure. Key sections to adapt:

## Agents — Add project agents above Core Agents
## Reference Examples — R1..RN with project's canonical files
## Phases — Each phase has: Agent, Status, Context (C#), Refs (R#)
## Phase NV: Verification — 2+ agents, one checks patterns compliance
## Final Review — 3+ agents parallel
## Context Index — C1..CN task-specific files

---

Phase 3.5: Copy and Adapt Review Skill

Agent: developer | Action: Copy review skill template and adapt for project

Create Review Skill Directory and Copy Template

EXECUTE using Bash tool — create directory and copy review skill template:

bash "scripts/setup.sh" review && echo "✅ review" || echo "❌ review FAILED"

STOP if ❌ — verify review template exists in plugin.

Adapt Review Skill

Replace placeholders based on Phase 2 analysis:

Placeholder	Source	Example
{PROJECT_AGENTS_TABLE}	.claude/agents/ scan	| db_expert | PostgreSQL | DB layer |
{TECH_SPECIFIC_CHECKS}	Detected tech stack	See Tech-Specific Checks below
{PROJECT_RULES}	CLAUDE.md patterns	AssertJ rules, Lombok, logging
{MAIN_AGENT}	Project agent or reviewer	reviewer
{TEST_AGENT}	Project agent or tester	tester
{DB_AGENT}	Project agent or sql_expert	db_expert
{CUSTOM_GROUPS}	Additional review groups	Security, API validation
{CODEBASE_BLOCKS}	Detected source patterns	src/main/**, src/test/**

Validation

EXECUTE using Bash tool — verify review skill:

test -f .claude/skills/brewcode-review/SKILL.md && echo "✅ Review skill created" || echo "❌ Review skill MISSING"
grep -q "Tech-Specific\|tech-specific\|Category.*Checks" .claude/skills/brewcode-review/SKILL.md && echo "✅ Tech checks" || echo "❌ Tech checks MISSING"

STOP if any ❌ — review skill must be created before continuing.

Phase 3.6: Copy Configuration

Agent: developer | Action: Copy configuration template for runtime settings

EXECUTE using Bash tool — copy/update config template:

bash "scripts/setup.sh" config && echo "✅ config" || echo "❌ config FAILED"

STOP if ❌ — verify .claude/tasks/cfg directory exists.

Configuration Options

Setting	Default	Description
knowledge.maxEntries	100	Max KNOWLEDGE.jsonl entries after compaction
knowledge.maxTokens	500	Max tokens in ## K block injected to agents
knowledge.priorities	["❌","✅","ℹ️"]	Priority order for knowledge entries
stop.maxAttempts	20	Stop attempts before escape mechanism triggers
agents.system	[...]	System agents (don't receive ## K injection)

Hooks-only architecture: No external runtime. All context management via Claude Code hooks.

---

Phase 4: Validation

Agent: developer | Action: Verify template structure

EXECUTE using Bash tool — ALL must pass:

bash "scripts/setup.sh" validate && echo "✅ validate" || echo "❌ validate FAILED"

STOP if any ❌ — go back to "Copy Templates" step and fix.

Validation Report

Check	Status
PLAN template	.claude/tasks/templates/PLAN.md.template
SPEC template	.claude/tasks/templates/SPEC.md.template
KNOWLEDGE template	.claude/tasks/templates/KNOWLEDGE.jsonl.template
Config file	.claude/tasks/cfg/brewcode.config.json
Project agents	[N] from .claude/agents/
Reference Examples	[N] canonical files populated
Tech-specific adaptations	Testing framework, DB patterns
Review skill	.claude/skills/brewcode-review/SKILL.md

---

Phase 5: Update Global CLAUDE.md Agents

Agent: developer | Action: Update agents section in global CLAUDE.md

Step 1: Collect Agents

EXECUTE using Bash tool:

bash "scripts/setup.sh" agents > /tmp/agents-section.md && cat /tmp/agents-section.md

Output = Ready-to-insert content. Script collects system + global + plugin agents. Internal agents (bc-coordinator, bc-grepai-configurator, bc-knowledge-manager) are automatically excluded.

Step 2: Analyze Existing CLAUDE.md

READ ~/.claude/CLAUDE.md using Read tool.

LLM Analysis — find ALL agent-related sections:

• ## Agents, ## Agent Selection, ### Core Agents, ### Global Utility Agents
• Any tables with columns like Agent | Model | Purpose
• Any lists of agent names (developer, tester, reviewer, etc.)

Identify boundaries:

• Start line number of agent section(s)
• End line number (before next unrelated ## heading)

Step 3: Ask User

ASK USER with AskUserQuestion:

• Question: "Found agent sections in ~/.claude/CLAUDE.md. Replace with optimized LLM-friendly format?"
• Options:
  • "Yes — replace all agent sections"
  • "No — keep current format"

Step 4: If YES — Replace

CRITICAL: Use EXACTLY the content from /tmp/agents-section.md. DO NOT add agents manually — the script already filters internal agents. Internal agents (bc-coordinator, bc-grepai-configurator, bc-knowledge-manager) are excluded by design.

Using Edit tool:

1. Read /tmp/agents-section.md to get the exact replacement content
2. Find the ## Agents — DELEGATE! section in ~/.claude/CLAUDE.md
3. Replace that section with the EXACT content from /tmp/agents-section.md
4. Preserve ### Global Skills subsection if it exists (append after agents table)
5. Preserve all non-agent content

Key: LLM determines section boundaries, not grep. Content comes from script output.
