feature-plan

feature-plan is a skill for Claude Code from Simone-Tarantino/godot-superpowers. It costs 82 tokens per session (2,728 once invoked), scanned A, original, MIT.

A milestone-based technical plan for implementing an approved feature in an existing Godot game. It maps the feature to files, work assignments, and regression tests, which check that existing behavior still works.

In plain words
What is it for?
Use it after a feature specification has been approved, especially before assigning implementation work on an existing game project.
Why use it?
It turns an approved feature description into concrete, ordered implementation work and identifies what must be tested before coding starts.

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

feature-plan 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 9d 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.

The opening of the file, as written. The whole thing — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feature Plan

Converts an approved feature spec into an actionable, milestone-based implementation plan that uses the godot-superpowers skill catalog as building blocks. Counterpart of writing-game-plan for changes on top of existing code.

When to invoke

  • Immediately after feature-spec has been approved by the user (the standard handoff).
  • When picking up a feature that already has a spec but no plan.
  • When re-planning after a major scope change to the spec — write a NEW plan file; do not edit the old one.

Inputs

  • The feature spec (passed as argument, or located via docs/features/*-feature.md of the same slug). Read it fully. The spec's header Survey reference: field is canonical:
    • If it points to a survey file path, that survey is mandatory input — read it fully; it dictates which existing files the plan touches.
    • If it is exactly none (trivial shortcut), the trivial-feature shortcut is in effect (see below). No survey input is required.
    • Any other value is a drift error — stop and route the user back to feature-spec to repair the header before planning.
  • Current project state — git status, ls, autoloads registered, addons installed.

Trivial-feature shortcut (mirrored from feature-spec)

A feature is trivial iff ALL of: touches one file, adds no new mechanic, adds no new public surface (no new signal / exported var / autoload / input action). The feature-spec declares this by writing Survey reference: none (trivial shortcut) in the spec header.

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.
