ITP Setup

Verify and install dependencies required by the /itp:go workflow using TodoWrite-driven interactive workflow.

---

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

MANDATORY FIRST ACTION

YOUR FIRST ACTION MUST BE TodoWrite with the template below.

DO NOT:

• Run any checks before TodoWrite
• Skip the interactive gate
• Install without user confirmation

Execute this TodoWrite template EXACTLY:

TodoWrite with todos:
- "Setup: Detect platform (macOS/Linux)" | pending | "Detecting platform"
- "Setup: Check Core Tools (uv, gh, prettier)" | pending | "Checking Core Tools"
- "Setup: Check ADR Diagram Tools (cpanm, graph-easy)" | pending | "Checking ADR Tools"
- "Setup: Check Code Audit Tools (ruff, semgrep, jscpd, gitleaks)" | pending | "Checking Audit Tools"
- "Setup: Check Release Tools (node, semantic-release)" | pending | "Checking Release Tools"
- "Setup: Present findings and disclaimer" | pending | "Presenting findings"
- "Setup: GATE - Await user decision" | pending | "Awaiting user decision"
- "Setup: Install missing tools (if confirmed)" | pending | "Installing missing tools"
- "Setup: Verify installation" | pending | "Verifying installation"

After TodoWrite completes, proceed to Phase 1 below.

---

Phase 1: Preflight Check

Mark each todo as in_progress before starting, completed when done.

Todo 1: Detect Platform

/usr/bin/env bash << 'SETUP_EOF'
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/itp}"
source "$PLUGIN_DIR/scripts/install-dependencies.sh" --detect-only
SETUP_EOF

Platform detection sets: OS, PM (package manager), HAS_MISE

Todo 2: Check Core Tools

Check each tool using command -v:

| Tool | Check | Required | | -------- | --------------------- | -------- | | uv | command -v uv | Yes | | gh | command -v gh | Yes | | prettier | command -v prettier | Yes |

Record findings:

• Found: [OK] uv (installed) -> mark completed
• Missing: [x] prettier (missing) -> note for Phase 3

Todo 3: Check ADR Diagram Tools

| Tool | Check | Required | | ---------- | --------------------------------- | ------------ | | cpanm | command -v cpanm | For diagrams | | graph-easy | echo "[A]" \| graph-easy (test) | For diagrams |

Todo 4: Check Code Audit Tools

| Tool | Check | Required | | -------- | --------------------- | --------------- | | ruff | command -v ruff | For code-audit | | semgrep | command -v semgrep | For code-audit | | jscpd | command -v jscpd | For code-audit | | gitleaks | command -v gitleaks | For secret-scan |

Todo 5: Check Release Tools

| Tool | Check | Required | | ---------------- | -------------------------------- | ------------- | | node | command -v node | For release | | semantic-release | npx semantic-release --version | For release | | doppler | command -v doppler | For PyPI only |

---

Phase 2: Present Findings (Interactive Gate)

Todo 6: Present Findings

IMPORTANT: Use mise-first commands when available

When presenting missing tool installation commands:

• If HAS_MISE=true (detected in Todo 1): Show mise commands
• If HAS_MISE=false: Show platform package manager commands (brew/apt)

Mise command reference (use when HAS_MISE=true):

| Tool | mise command | Notes | | -------- | -------------------------------- | ------------------------------ | | gitleaks | mise use --global gitleaks | | | ruff | mise use --global ruff | | | uv | mise use --global uv | | | gh | brew install gh | NEVER mise (iTerm2 issues) | | semgrep | mise use --global semgrep | | | node | mise use --global node | | | doppler | mise use --global doppler | | | prettier | mise use --global npm:prettier | | | jscpd | npm i -g jscpd (npm only) | |

Warning: gh CLI must be installed via Homebrew, not mise. mise-installed gh causes iTerm2 tab spawning issues with Claude Code. ADR

Display summary format (versions derived from actual tool output):

=== SETUP PREFLIGHT COMPLETE ===

Found: X tools | Missing: Y tools

Your existing installations:
[OK] uv (<derived from: uv --version>)
[OK] gh (<derived from: gh --version>)
[x] gitleaks (missing)
...

Note: This plugin is developed against latest tool versions.
Your existing installations are respected.

Missing tools will be installed via mise (detected):
  gitleaks -> mise use --global gitleaks

If HAS_MISE=false, show platform commands instead:

Missing tools will be installed via brew:
  gitleaks -> brew install gitleaks

IMPORTANT: Version numbers must be derived dynamically from running the actual tool's version command. Never hardcode version numbers.

Todo 7: GATE - Await User Decision

If missing tools exist, STOP and ask user:

Use AskUserQuestion with these options:

question: "Would you like to install the missing tools?"
header: "Install"
options:
  - label: "Install missing"
    description: "Automatically install all missing tools"
  - label: "Skip"
    description: "Show manual install commands and exit"

IMPORTANT: Do NOT proceed to Phase 3 until user responds.

If ALL tools present: Mark todo completed, skip to "All set!" message, mark todos 8-9 as N/A.

---

Phase 3: Installation (Conditional)

Todo 8: Install Missing Tools

Only execute if:

• User selected "Install missing"
• OR --install flag was passed (skip interactive gate)

Run installation commands for missing tools only:

/usr/bin/env bash << 'SETUP_EOF_2'
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/itp}"
bash "$PLUGIN_DIR/scripts/install-dependencies.sh" --install
SETUP_EOF_2

If user selected "Skip":

• Display manual install commands
• Mark todo as skipped
• Exit cleanly

Todo 9: Verify Installation

Re-run checks to confirm tools are now available:

/usr/bin/env bash << 'PREFLIGHT_EOF'
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/itp}"
bash "$PLUGIN_DIR/scripts/install-dependencies.sh" --check
PREFLIGHT_EOF

Mark todo completed only if verification passes.

---

Flag Handling

| Flag | Behavior | | ----------- | ------------------------------------------- | | (none) | Default: Check -> Gate -> Ask permission | | --check | Same as default (hidden alias) | | --install | Check -> Skip gate -> Install automatically | | --yes | Alias for --install |

Parse $ARGUMENTS for flags:

case "$ARGUMENTS" in
  *--install*|*--yes*)
    SKIP_GATE=true
    ;;
  *)
    SKIP_GATE=false
    ;;
esac

---

Edge Cases

| Case | Handling | | --------------------------------- | ----------------------------------------------------------------- | | All tools present | Todos 1-6 complete, Todo 7 shows "All set!", Todos 8-9 marked N/A | | Some missing, user says "install" | Todos 8-9 execute normally | | Some missing, user says "skip" | Show manual commands, mark todos 8-9 as skipped | | --install flag passed | Skip Todo 7 gate, proceed directly to install | | macOS vs Linux | Todo 1 detects platform, install commands adapt |

Troubleshooting

graph-easy fails to install

# Ensure cpanminus is installed first
brew install cpanminus

# Then install Graph::Easy
cpanm Graph::Easy

semantic-release not found

# Install globally with npm
npm i -g semantic-release@25

# Or use npx (no global install needed)
npx semantic-release --version

Permission errors with npm

/usr/bin/env bash << 'CONFIG_EOF'
# Fix npm permissions
mkdir -p ~/.npm-global
npm config set prefix '~/.npm-global'

# Add to your shell config
SHELL_RC="$([[ "$SHELL" == */zsh ]] && echo ~/.zshrc || echo ~/.bashrc)"
echo 'export PATH=~/.npm-global/bin:$PATH' >> "$SHELL_RC"
source "$SHELL_RC"
CONFIG_EOF

---

Next Steps

After setup completes, configure itp-hooks for enhanced workflow guidance:

1. Check hook status:

   /itp:tether status
   

2. Install hooks (if not already installed):

   /itp:tether install
   

What hooks provide

• PreToolUse guard: Blocks Unicode box-drawing diagrams without <details> source blocks
• PostToolUse reminder: Prompts ADR sync and graph-easy skill usage

IMPORTANT: Hooks require a Claude Code session restart after installation.

Post-Execution Reflection

After this skill completes, reflect before closing the task:

0. Locate yourself. — Find this SKILL.md's canonical path (Glob for this skill's name) before editing. All corrections target THIS file and its sibling references/ — never other documentation.
1. What failed? — Fix the instruction that caused it. If it could recur, add it as an anti-pattern.
2. What worked better than expected? — Promote it to recommended practice. Document why.
3. What drifted? — Any script, reference, or external dependency that no longer matches reality gets fixed now.
4. Log it. — Every change gets an evolution-log entry with trigger, fix, and evidence.

Do NOT defer. The next invocation inherits whatever you leave behind.
