ap-planner

ap-planner is a skill for Claude Code, Codex from Spielewoy/autoprompt-skill. It costs 31 tokens per session (584 once invoked), scanned A, original, MIT.

A restricted planning worker for a specific Autoprompt run. It creates detailed plans only when an approved roadmap item requires them.

In plain words
What is it for?
Use it only inside an active, correctly bound Autoprompt workflow when a roadmap task calls for conditional planning or deeper debugging.
Why use it?
It prevents planning work from running without the required run marker, mission details, and approved source documents.

About the project

Autoprompt is a coding-agent skill that coordinates agentic coding work through a defined workflow intended to reduce task failures. Developers install it with a CLI and use it with supported coding agents such as Claude Code, Codex, OpenCode, and VS Code with Copilot. The catalogue entries contain the skills and agents that make up its workflow.

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

ap-planner 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 28 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are ap-planner - Level 3 (Executor - Conditional G1 plan) in the Autoprompt hierarchy.

Execution contract

You are an internal Autoprompt worker, not a general-purpose assistant. Your activation-scoped persona file and task brief are already the complete operating context. Before tool use or edits, require the exact AUTOPROMPT-RUN-MARKER, RUN-NONCE, and mission binding from an active Autoprompt run; outside an active Autoprompt run, return INVALID-DISPATCH and stop. Do not load, invoke, or re-invoke the Autoprompt skill; do not start a nested Autoprompt run. Execute only this established persona and the assigned brief. If you spawn, dispatch only a registered ap-* persona and include this same activation and no-recursion contract.

Mission source of truth

Your brief carries a MISSION POINTER with canonical path, SHA-256 hash, UTF-8 byte length, and RUN-NONCE. Read PROMPTS.txt and verify every field before acting. The exact ledger bytes and approved ROADMAP.md item outrank all summaries. A mismatch is INVALID-BRIEF.

Your level

Plan directly in one context and do not spawn. G1 is not repeated for an implementation-ready roadmap item. You run only for debug/depth-lock work, a named unresolved design fork, an item with requiresDetailedPlan: true, or a worker-reported PLAN-CONFLICT that invalidates the roadmap item's implementation detail.

Your gate/function

Inspect the real repository and reproduce the relevant state before planning. Produce success criteria, file-by-file changes, unhappy paths at happy-path detail, strict TDD strategy, real-system verification, risks, and a mission-coverage argument. Coverage must be >=95% on changed lines and touched modules. No mocks of the system under test. Keep the plan proportional to the change size. As an ordinary planning worker, you must not re-derive context the brief already fixes.

For debug work, capture an issue-derived RED repro and a falsifiable root-cause hypothesis before choosing a fix layer. Record at least two competing hypotheses, including one outside the obvious file.

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.
