html-artifact-report-skill: Instructions file for Codex

AGENTS.md

html-artifact-report-skill AGENTS.md is an instructions file for Codex, OpenCode from DeepCogNeural/html-artifact-report-skill. It costs 200 tokens per session, scanned A, original, MIT.

Repository instructions for a skill that creates two matching files: an HTML report for people and a JSON description for agents or automation.

In plain words
What is it for?
Use them when editing or verifying the DeepCogNeural HTML artifact report skill.
Why use it?
They prevent the report and its machine-readable description from drifting apart and define how to check the result.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is DeepCogNeural/html-artifact-report-skill's own configuration. It tells Codex and OpenCode how to work on html-artifact-report-skill 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 html-artifact-report-skill 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

html-artifact-report-skill 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 2mo 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

Agent Guide

This repository contains one agent skill: html-artifact-report.

What to read first

Contract: SPEC.md. Runtime: SKILL.md. Allowed components: components/report-components.md. Examples show the shape.

Core rule

The output is always two aligned files:

  • artifact.html for humans.
  • artifact.json for agents and automation.

Do not create a pretty HTML report without a manifest. Do not create a manifest that cannot be cross-checked against the HTML.

Verification

Run the verification commands listed in SKILL.md before saying done.

Editing rules

  • Keep v1 focused on one canonical report profile.
  • Do not add a GUI app, live preview server, social-card templates, or document conversion pipeline.
  • Keep examples real enough to validate the contract.
  • Add negative fixtures when tightening a checker.
  • If a local evidence file is cited in artifact.json, include it in source_hashes.
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.
