plan

plan is a skill for Claude Code from naniiluja/ccf. It costs 99 tokens per session (3,603 once invoked), scanned A, original, MIT.

A planning workflow for CCF projects that creates a strictly ordered implementation plan after an interview and codebase investigation. CCF is the project’s own planning system, and plan mode is a restricted state for preparing changes without implementing them.

In plain words
What is it for?
Use it to plan a feature or change, inspect the codebase, and create one task file for each implementation step.
Why use it?
It prevents planning from starting in the wrong mode and turns a requested change into explicit, repository-grounded tasks.

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

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 16d 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are running CCF /ccf:plan.

0. Plan-mode gate (backup for the hook)

STOP. Confirm this session is in plan mode before anything else. If it is not, refuse to continue: tell the user to enter plan mode (Shift+Tab cycles to 'plan', or start the session with --permission-mode plan), then re-run /ccf:plan. Do not run any step below. The plan-mode-guard hook blocks this deterministically too; this sentence is the backup for the case where the hook does not fire.

0a. Style for user-facing text (applies to every step below that writes text into the plan)

Scope boundary: this rule governs CCF-generated text meant for the human reader (the plan body, task files, explanations to the user). It does NOT apply to the CCF repo's own source, which stays English per .claude/rules/components.md (never translate the repo itself).

  • Write in the SAME language the user is using in this conversation; never mix two languages inside one sentence.
  • Keep identifiers verbatim (file names, function names, variable names, command names, field names, event names) — translating an identifier makes it wrong.
  • Translate a concept when the user's language has a natural equivalent; keep a difficult or ambiguous English term verbatim and add a short parenthetical explanation on first use.
  • No em dash; use a comma, colon, or parentheses instead.
  • One idea per sentence; split a sentence longer than two lines.
  • A language that uses diacritics (e.g. Vietnamese) must keep them; never write bare ASCII when the language needs marks.
  • Do not invent abbreviations; if one is used, spell it out on first use.
  • Open with the point itself; never with generic filler. End when the content ends; never restate what was just said as a summary.
  • Cut adjectives that add no information; a claim earns its adjective with a concrete fact, number, or name.
  • Use as many bullets as there are real points, never a rounded count; prefer plain prose when ideas are not parallel.
  • Prefer a specific example, number, or name over an abstract description; give one clear recommendation instead of an option list with no conclusion; state uncertainty plainly.
  • Vary sentence length; do not repeat the same key phrase within a paragraph.
  • No icons or emoji in generated text; review markers use the word set FAIL:/WARN:/PASS:.

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.
