skills: Instructions file for Codex

AGENTS.md

skills AGENTS.md is an instructions file for Codex, OpenCode from creght-dev/skills. It costs 846 tokens per session, scanned A, original, MIT.

Repository guidance for maintaining the Creght coding-agent skill and keeping it consistent with related Talizen skills. It explains which audience and workflow each skill serves.

In plain words
What is it for?
Use it when editing, synchronising, or rebranding Creght and Talizen agent-skill instructions.
Why use it?
It prevents contributors from mixing up the in-editor platform workflow with the local command-line workflow or letting related skills drift apart.

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

This is creght-dev/skills's own configuration. It tells Codex and OpenCode how to work on skills 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 skills 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

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 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.

AGENTS.md — how the Creght / Talizen skills relate

This repo holds the external Creght skill. It is one of three sibling agent-skills for the same platform; they share most guidance but target different audiences and must be kept consistent. Read this before editing.

The three skills

Skill Location Audience Tooling model
talizen-system talizen-system/ in the talizen/skills repo The in-platform agent that runs inside the Talizen / Creght editor Has platform tools: lint, create_version, diff_patch_file, fetch_module_types, import-map, preview. No CLI workflow.
talizen (external) skills/talizen/ in the talizen/skills repo End users / general-purpose agents working locally via the Talizen CLI CLI workflow (pull / push / watch / preview). Platform tools only "if the environment exposes them, otherwise use the CLI".
creght (external) skills/creght/ (this repo) End users of Creght Same as external talizen, but Creght-branded.
  • Creght integrates Talizen's capabilities, and Talizen is also operated as an independent platform. Creght and Talizen therefore share the same code model and SDK — the only differences are the platform name and branding.
  • talizen-system is the source of truth. It is the newest and most complete. This external Creght skill is downstream and is kept in sync with its audience-neutral content, then rebranded (see below).

Syncing content from talizen-system → this skill

Do not blind-copy. When porting guidance from talizen-system:

  1. Filenames — all three skills use lowercase kebab-case under references/ (cms.md, forms.md, error-handling.md, site-code.md); SKILL.md links files by name, so keep this consistent across the three.
  2. Keep external-only files — cli.md and site-code.md exist only in the external skills (they document the CLI / local workflow). talizen-system has no equivalent; never delete them during a sync.
  3. Filter platform-only content — strip or rewrite anything that assumes the in-platform agent: the lint / create_version / diff_patch_file / fetch_module_types / create_collection / import-map tools, and the LINT_ERROR / BROWSER_ERROR_RENDER events plus preview-runtime specifics. Those events are delivered only to the in-platform agent — a local CLI agent never receives them, so external docs must not wait for or trigger on them. Re-express as CLI / general guidance, or drop it.
  4. error-handling is intentionally its own document — talizen-system keeps a platform/preview version (BROWSER_ERROR_RENDER, preview-runtime, the built-in React runtime). This skill carries a CLI-oriented version. Keep them separate; do not merge them back into one.

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.
