pyapple-mcp: Skill for Claude Code

.claude/skills/pyapple/SKILL.md

pyapple is a skill for Claude Code from 54yyyu/pyapple-mcp. It costs 98 tokens per session (13,454 once invoked), scanned A, original, MIT.

A skill for handling a software project through written planning, test-driven development, and a continuously updated project wiki. Test-driven development means writing tests before or alongside the code they check.

In plain words
What is it for?
Use it to plan features, propose changes, implement them with tests, review the result, update the wiki, or query existing project knowledge.
Why use it?
It provides a repeatable path from an idea to an implementation, review, and recorded project knowledge.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is 54yyyu/pyapple-mcp's own configuration. It tells Claude Code how to work on pyapple-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pyapple-mcp configures →

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Memory Poisoning · line 261
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.
  • high Anti-Refusal · line 593
    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

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 A, and why

pyapple scanned grade A with 0 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Driving pyapple

pyapple reads and writes eight Apple apps on the machine it runs on, and answers two questions about the machine itself. §1 is the lookup table: find the operation, copy the shape, go. Everything after it is what the shape does not tell you.

pyapple <tool> <operation> --help remains the authority on defaults and semantics. Ten tools — messages, mail, contacts, reminders, calendar, notes, maps, shortcuts, presence, doctor — plus pyapple perms, which is not a tool.

Two things to reach for before you go anywhere else. After any exit 3, run pyapple doctor report — it says which macOS grant is missing and where to click, and it distinguishes that from a grant it could not determine (§2). And if a send comes back saying Nothing was sent, that is not a failure: this install requires confirmation, and §11 is the flow.


1. Every operation, and its shape

88 operations. <x> is positional, [x] optional, A|B a fixed choice. --json, --read-only and --perms work on every one of them and are omitted here. The class column is what the policy gate charges (§7). --confirm-token is omitted too and belongs to §11; it is on messages send, messages send-attachment, messages schedule, mail send, mail reply and mail forward.

Seven flags take a space-separated list, not a comma-separated one: messages conversations --participants, and on calendar --invitees, --recurrence-days, --minutes-before, --alarm-minutes-before, --alarm-at. Writing --invitees "[email protected],[email protected]" makes one malformed address, and on --invitees that address gets mail.

Spellings below are canonical, and a handful of flags answer to a second name so that a wrong guess works rather than exiting 2 — --since/--until on calendar windows, --from-date on mail and messages reads, --from-address/--to-address on maps directions, --id for --event-id and --chat-id, --contact for contacts --name, --title/--name either way round on a create. Use the canonical one; the full table is in the README's Alternative flag spellings. Nothing was renamed and no old spelling was removed.

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.
