init

init is a skill for Claude Code from bentleypark/claude-code-mobile-spine. It costs 99 tokens per session (6,917 once invoked), scanned B, original, MIT.

A setup guide that creates a new mobile development workspace for Android, iOS, and backend projects kept in separate code repositories. It asks for your project details, then fills in the workspace files.

In plain words
What is it for?
Use it to start a mobile project workspace with the right organisation, app, branch, design-tool, and licence details. It prepares the files needed to coordinate work across Android, iOS, and backend repositories.
Why use it?
It removes the manual work of copying templates and replacing project-specific placeholders. It also records your answers so the shared development agents can use the same settings.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

init scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (smoke-test.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 461 lines — stays where its author put it; the contents beside it link to each section on GitHub.

mobile-spine:init

Bootstrap a new mobile-spine workspace by interviewing the user, then writing the user-customizable files into the chosen install location and a .claude/mobile-spine.config.yaml capturing the interview answers.

The static templates this skill consumes live next to this SKILL.md under ./templates/. They are workspace-data only — CLAUDE.md, SETUP.md, README.md, LICENSE, .gitignore, .claude/settings.json, a thin .claude/commands/feat.md stub, _context/operations.md, plus .gitkeep files for empty directories.

Not scaffolded — the five subagents (api-agent / pm-agent / android-agent / ios-agent / docs-agent) and the full /feat / /feasibility command logic are plugin primitives (live in plugins/mobile-spine/agents/ and plugins/mobile-spine/commands/, served globally by the plugin). The workspace's .claude/commands/feat.md is a thin delegation stub. The repo-facing agents read .claude/mobile-spine.config.yaml at invocation to pick up the workspace's org / app / baseBranch / figma / copyright values (docs-agent reads no config). This means /plugin marketplace update claude-code-mobile-spine propagates agent + /feat / /feasibility improvements to every workspace automatically — without modifying any workspace-owned file.

Step 1 — Locate the templates directory

Resolve in three tiers. The harness should set $CLAUDE_PLUGIN_ROOT for plugin-installed runs, but in practice this is not guaranteed (e.g. for directory-typed marketplaces or older Claude Code versions). The cache and working-tree fallbacks make the skill robust to either case.

TEMPLATES_DIR=""

# Tier 1 — plugin-installed via $CLAUDE_PLUGIN_ROOT (canonical when set).
# Skip when unset to avoid expanding to "/skills/init/templates" (absolute,
# never matches).
if [ -n "${CLAUDE_PLUGIN_ROOT:-}" ]; then
  cand="$CLAUDE_PLUGIN_ROOT/skills/init/templates"
  if [ -f "$cand/CLAUDE.md" ] && [ -f "$cand/SETUP.md" ]; then
    TEMPLATES_DIR="$cand"
  fi
fi

# Tier 2 — known plugin cache (versioned glob). Picks the first matching
# version under $HOME/.claude/plugins/cache/.../mobile-spine/<ver>/.
if [ -z "$TEMPLATES_DIR" ]; then
  for cand in "$HOME/.claude/plugins/cache/claude-code-mobile-spine/mobile-spine"/*/skills/init/templates; do
    if [ -f "$cand/CLAUDE.md" ] && [ -f "$cand/SETUP.md" ]; then
      TEMPLATES_DIR="$cand"
      break
    fi
  done
fi

# Tier 3 — source-tree fallbacks (plugin development from a working checkout).
if [ -z "$TEMPLATES_DIR" ]; then
  for cand in \
    "$(pwd)/plugins/mobile-spine/skills/init/templates" \
    "$(pwd)/skills/init/templates" \
    "$(pwd)/templates"; do
    if [ -f "$cand/CLAUDE.md" ] && [ -f "$cand/SETUP.md" ]; then
      TEMPLATES_DIR="$cand"
      break
    fi
  done

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

init is a skill published in the GitHub repository bentleypark/claude-code-mobile-spine (1 stars, last pushed 5d ago), licensed MIT. It adds 99 tokens to every session and 6,917 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
