kindle

kindle is a skill for Claude Code from iroha924/mumei. It costs 83 tokens per session (2,101 once invoked), scanned D, original, MIT.

A one-time project setup tool for mumei, a workflow that uses written specifications, review stages, and coordinated commits. It checks existing project instruction files and prepares mumei's folders and rules.

In plain words
What is it for?
Use it when first setting up or installing mumei in a project. It can inspect project guidance, propose additions, and create the required .mumei directory structure after approval.
Why use it?
It prevents mumei's expectations from conflicting with instructions already present in the project. It also gives the project a defined place for specifications, drafts, archives, and session state.

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 D, and why

kindle scanned grade D with 2 findings 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 10d ago.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kindle

Set up mumei for the current project. This skill is run once per project. It:

  1. Creates the .mumei/ directory structure.
  2. Detects existing CLAUDE.md / .claude/rules/*.md.
  3. Proposes additions about mumei's expectations and applies them with explicit user approval.

When to use

  • The user explicitly says "set up mumei", "install mumei in this project", or invokes /mumei:kindle.
  • The first time /mumei:compose is invoked in a project where .mumei/ does not exist (route to this skill first).

Method

Step 1 — Detect existing project memory

Read all of:

  • CLAUDE.md (project root)
  • .claude/CLAUDE.md
  • ~/.claude/CLAUDE.md (user-level, read-only)
  • .claude/rules/*.md
  • AGENTS.md (if present)

Summarize what is currently in place. Do NOT modify anything yet.

Step 2 — Create .mumei/ directory and its .gitignore

mkdir -p .mumei/specs .mumei/archive .mumei/scratch
[[ -f .mumei/current ]] || : > .mumei/current  # empty until first feature

Generate .mumei/.gitignore so team-shared spec content (requirements / design / tasks / spec-reviews / reviews / scratch / archive) is tracked, while per-developer state (current cursor, state.json progress) is ignored. Do not overwrite an existing .mumei/.gitignore — the user may have customized it.

if [[ ! -f .mumei/.gitignore ]]; then
  cat > .mumei/.gitignore <<'EOF'
# mumei: per-developer state only. Everything else (config.json,
# specs/*/{requirements,design,tasks}.md, spec-reviews/, reviews/, scratch/,
# archive/) is tracked for team handoff — config.json carries golden_paths, so
# it MUST be committed for G1/G2 to behave the same across teammates / CI.

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.
