agent-skills AGENTS.md

agent-skills AGENTS.md is an instructions file for Codex, OpenCode from fluxcd/agent-skills. It costs 809 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for creating and maintaining AI skills for Flux CD, Kubernetes, and GitOps. They describe the folder layout, helper scripts, reference files, schemas, and evaluation tests.

In plain words
What is it for?
Use them when editing a Flux-related skill, refreshing validation scripts, adding tests or schemas, or running the repository’s skill evaluations.
Why use it?
They give contributors a consistent way to update existing skills or add new ones without breaking validation or distribution files.

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

agent-skills AGENTS.md 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.

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.

Agent Instructions

This repository contains AI agent skills for Flux CD, Kubernetes, and GitOps. Skills follow the Agent Skills Open Standard.

skills/gitops-repo-audit/scripts/validate.sh is vendored from the flux-schema action (the single source of truth). Don't edit it here — run make sync-validate to refresh it, and send changes upstream.

Working on Existing Skills

  1. Read the skill's SKILL.md to understand its workflow and allowed tools
  2. Read all files in references/ and scripts/ before making changes
  3. Keep SKILL.md under ~15KB — heavy reference material belongs in references/

Running Skill Evals

Each skill has an evals/evals.json file with evaluation scenarios. When asked to run them:

  1. Read evals/evals.json to get the list of eval prompts and their expectations
  2. For each eval, spawn a sub-agent with this prompt template:
    You are a [skill role]. load the skill from `skills/{skill-name}/SKILL.md`
    exactly — read it first, then follow the workflow phases.
    
    Your task: [eval prompt from evals.json]
    
    Important:
    - Do not seach the web, use only the skill references and your own reasoning
    - Produce the full structured report as specified in the workflow if there is one
    
  3. Score each eval output against the expectations array — each expectation is a pass/fail check
  4. Report results as a scorecard: eval id, pass/fail counts, and any missed expectations

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.
