claude-code-framework: Skill for Claude Code

.claude/skills/ccf-dogfood-and-drift/SKILL.md

ccf-dogfood-and-drift is a skill for Claude Code from BostonOrange/claude-code-framework. It costs 138 tokens per session (3,545 once invoked), scanned A, original, MIT.

Instructions for maintaining the claude-code-framework repository’s own local configuration copy and checking it against the distributable templates. Dogfooding here means the project runs a copy of its own product inside the repository.

In plain words
What is it for?
Use it when editing the repository’s `.claude` agents, hooks, skills, statusline, or local settings, or when the dogfood-drift test reports unexpected or outdated differences.
Why use it?
It explains why files under `.claude/` may differ from templates and how those differences are controlled. This helps diagnose drift-check failures without making unapproved configuration changes.

Skill for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

This is BostonOrange/claude-code-framework's own configuration. It tells Claude Code how to work on claude-code-framework 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 claude-code-framework configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash tests/check-dogfood-drift.sh.

Nothing to install: this file belongs to BostonOrange/claude-code-framework. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

ccf-dogfood-and-drift 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.

Dogfood Model and Drift Policing

Dogfooding here means: this repo runs a copy of its own product under .claude/. But .claude/ is not a setup.sh install — it is a hand-curated subset, and every byte of divergence between .claude/ and the distributable sources is policed by an explicit allowlist (config/dogfood-drift-allowlist.txt) enforced by tests/check-dogfood-drift.sh.

Usage

Load this skill when:

  • tests/check-dogfood-drift.sh fails (unexpected or stale entries).
  • You are adding, modifying, or removing anything under .claude/agents/, .claude/hooks/, .claude/skills/, .claude/statusline/, or .claude/settings.local.json.
  • You are adding a template skill/agent/hook that will NOT be dogfooded (that also changes the drift surface — see Edge Cases).
  • You need to decide: allowlist a divergence, or sync it back to the template?

Do NOT use this skill for:

  • The full test-suite anatomy or "am I done?" gating — see ccf-testing-and-qa.
  • Doc counts/tables (README, CLAUDE.md, AGENTS.md) — see ccf-doc-sync-campaign.
  • Whether a change may merge at all, commit conventions — see ccf-change-control.
  • Why the repo separates templates/ vs skills/ vs global-skills/ — see ccf-architecture-contract.

Process: touching anything the drift check compares

Phase 1 — Classify your change

You are... Go to
Adding a repo-local file under .claude/ (skill, agent) Phase 2
Modifying a dogfooded copy of a template file Phase 3
Removing anything (either side) Phase 4
Adding a template-side skill/agent/hook that is NOT dogfooded Edge Cases table

Phase 2 — Add a repo-local skill or agent

mkdir -p .claude/skills/<name>
# write .claude/skills/<name>/SKILL.md
printf 'Only in .claude/skills: %s\n' '<name>' >> config/dogfood-drift-allowlist.txt
bash tests/check-dogfood-drift.sh

For a repo-only agent the line is Only in .claude/agents: <name>.md (note .md — agents are compared per-file, skills per-directory). The script sorts everything, so line position doesn't matter for correctness — but group lines under the file's existing comment headers for humans.

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.
