ccf-common

ccf-common is a skill for Claude Code, Codex from mikubaka88/CCFA-Skills. It costs 43 tokens per session (986 once invoked), scanned A, original, MIT.

A shared rulebook for the CCFA family of skills, covering how tasks are routed, evidence and privacy are handled, and outputs are structured.

In plain words
What is it for?
Use it when maintaining or auditing CCFA skills, including their triggers, task modes, handoffs, source records, privacy rules, and artifact requirements.
Why use it?
It keeps related skills consistent and prevents this governance module from being used as a general research assistant.

About the project

CCFA Skills is a family of agent skills that helps researchers develop the storyline and presentation of CCF-A research papers. It supports work across research ideas, literature, experiments, writing, figures, reviews, rebuttals, and submission while keeping the argument connected. The catalogue entry consists of the project's research-writing skills and plugin.

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-common 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 4d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/check_markdown_links.py, scripts/check_path_privacy.py, scripts/check_sources.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

CCF Common

Core Rule

This is the shared control module for the CCFA Skills family. Do not use it as a user-facing research assistant module. Use it to keep routing, handoff behavior, source provenance, private-material handling, and score-risk language consistent across ccf-* skills and ccf-skill-forger.

Invocation Controls

CCFA Handoff Mode: PARTIAL (Recommended). Follow metadata.ccf_skill_controls.handoff_question_mode and references/handoff-modes.md. This skill provides shared policy only; route ordinary research tasks to the owning skill in references/routing.md.

Shared Controls

Load only the file needed for the current maintenance task:

  • references/routing.md: Use to resolve which CCFA skill owns a request and to avoid trigger overlap.
  • references/task-modes.md: Use for exploratory/quick/standard depth, authorization-aware continuation, selective context, host-supported parallel work, and GPT-6 adaptation.
  • references/review-output-standards.md: Use to keep numeric scoring, multi-reviewer panels, score-change conditions, and visible output quality consistent.
  • references/handoff-modes.md: Use to interpret metadata.ccf_skill_controls.handoff_question_mode.
  • references/privacy-and-evidence.md: Use when handling manuscripts, reviews, rebuttals, private drafts, literature searches, or evidence claims.
  • references/source-registry.yaml: Use as the shared source inventory for venue rules, review methods, exemplar records, and research-workflow references.
  • references/ccf-a-venue-map.md: Use when a non-writing skill needs venue-family mapping without depending on ccf-paper-writer.
  • references/skill-trigger-registry.yaml: Use as the canonical trigger registry; compare descriptions and agent prompts with the same ownership boundaries.
  • references/artifact-contracts.md: Use whenever a skill creates or revises files; it defines ownership, canonical paths, overwrite-in-place defaults, and the narrow cases that require retained history.
  • references/ccfa-yaml-contract.md: Use for the shared ccfa.yaml project-state schema.

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.
