.agents/skills/fkf-contribute/SKILL.md

fkf-contribute is a skill for Claude Code, Codex from fmind/fkf. It costs 32 tokens per session (328 once invoked), scanned A, original, MIT.

A contribution guide for the fkf repository, a code project with rules about its command-line tool, offline reading, trusted sources, documentation, and generated files.

In plain words
What is it for?
Making focused changes to fkf code, command-line behavior, configuration, presets, skills, tests, release files, or the Hugo website.
Why use it?
It helps contributors change the project without breaking agreements between code, tests, documentation, presets, and generated artifacts.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is fmind/fkf's own configuration. It tells Claude Code and Codex how to work on fkf 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 fkf configures →

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

fkf-contribute 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 1mo 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.

What it actually says

fkf-contribute

Read AGENTS.md first. Keep one package and command, authored projects/tasks/wiki Markdown, monthly JSON Lines records upserted by id, and a disposable, self-refreshing SQLite cache. Provider projection, schedules and harness installation belong to base maintenance. Keep only the current data format; do not add migration or compatibility code.

Test observable behavior and failures with synthetic data and fake providers. Preserve offline reads, readable refs that resolve to files, path confinement, bounded output, atomic writes, process cancellation, and explicit, per-machine trusted collection. Do not run live providers without task authorization or weaken a check.

Run focused tests and mise run all. Update schema, README, docs, the user skills under skills/ and the source examples under examples/sources/ with public behavior; an adapter change needs a fake-provider test and a README table entry. Preserve unrelated changes; commits, publication and provider execution follow the user's explicit scope.

For onboarding changes, execute the documented path in a disposable base with isolated config and state: save a decision, search, read, validate and evaluate it. Keep the README focused on the user's outcome, detailed contracts in docs and agent procedures in skills. Check actual host discovery separately from copying a skill or installing the package.

For an authorized publication, follow the release checklist; keep release mechanics there rather than in user workflows.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
