masterplan-detect

masterplan-detect is a skill for Claude Code, Codex from rasatpetabit/masterplan. It costs 116 tokens per session (1,398 once invoked), scanned A, original, MIT.

A rule that detects old /masterplan project bundles and suggests using the migration command only when the required legacy files are present. A legacy bundle is an older saved set of planning state files.

In plain words
What is it for?
Use it to decide whether an old masterplan bundle can be migrated or whether a fresh planning session is needed.
Why use it?
It prevents unsupported documents such as generic TODO or roadmap files from being treated as importable masterplan data.

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

masterplan-detect 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 3d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Central agent policy

AUQ, Serena, Hindsight, context-mode, and agent policy is centralized in AGENTS.md (routing resolves from policy/workflow-map.json; fleet policy at /srv/workflows/policy/dispatch.md). This skill must not duplicate or override dispatch rules. User-facing choices must use ask_user_question / AskUserQuestion, never prose questions.

Detecting legacy masterplan bundles for /masterplan import

This skill suggests, it does not act. The user must explicitly run /masterplan import (or, for non-importable artifacts, a fresh full/brainstorm) to act.

/masterplan import is not a generic legacy-document importer. It maps to mp migrate-bundle, which ingests only a legacy masterplan bundle's state.yml (schema_version 5.x) and re-freezes it into a v8 run. It cannot convert arbitrary planning markdown (PLAN.md, TODO.md, ROADMAP.md, design/RFC docs, PR task lists). Those have no import path — the honest suggestion for them is a fresh /masterplan brainstorm seeded from the repo context, never a claim that import will ingest them.

When to fire

The user is in a git repo and at least one of these is true:

  • A legacy masterplan bundle exists at docs/masterplan/<slug>/state.yml whose schema_version is 5.x (or predates 5.0, which import will refuse) and there is no matching already-migrated v8 run for the same <slug>.

That is the entire importable surface. The following are not importable, so they do not by themselves warrant an import suggestion:

  • A planning-shaped file lives at the repo root or in a common docs directory:
    • PLAN.md, TODO.md, ROADMAP.md, WORKLOG.md, NOTES.md
    • docs/plans/*.md, docs/design/*.md, docs/rfcs/*.md, architecture/*.md, specs/*.md
  • A pre-v3 masterplan artifact exists under docs/superpowers/{plans,specs,retros,archived-plans,archived-specs} and there is no matching docs/masterplan/<slug>/state.yml.
  • An open feature branch (not yet merged into the trunk) has descriptive name + commit history that suggests a tracked feature, but no masterplan status file exists for it.
  • A draft PR's body contains a task list (- [ ] / - [x] / numbered steps).

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.
