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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01798 | $0.01798 |
| Opus 5.5 | $0.00719 | $0.00719 |
| Sonnet 5.5 | $0.00360 | $0.00360 |
| Haiku 4.5 | $0.00180 | $0.00180 |
Grade A, and why
GameStudio-CodexKIT 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.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GameStudio-CodexKIT Operating Contract
Active Sources Of Truth
Use this precedence order:
AGENTS.mdfor operating, evidence, mutation, ownership, archive, and handoff rules..agents/skills/*/SKILL.mdand.codex/agents/*.tomlfor repository-local maintenance behavior while working in this repository.registry/*.yamlfor distributed capabilities, agent roles, packs, personas, skill resources, and upstream snapshot provenance.skills/*/SKILL.mdfor canonical distributed workflows.docs/architecture/overview.mdanddocs/authoring/skills.mdfor maintained design guidance.- Generated adapters as read-only optional export artifacts.
Files under the ignored local .archive/ are optional historical context only and never active policy or distributable template content.
Primary Distribution
- Codex App/CLI and Hermes Agent are the only primary runtime targets. Treat every other export as optional maintenance output.
- The repository root is the installable plugin;
skills/remains the only canonical distributed workflow source. .codex-plugin/plugin.jsondefines the plugin identity and exposes./skills/directly..claude-plugin/marketplace.jsonis the Codex-supported repository marketplace compatibility path used by the GitHub install flow.- Hermes Agent installs the same canonical catalog through
npx skills add <repo> -a hermes-agent; the CLI copies individual skill directories, so runtime helpers must be bundled inside each skill. - Generated Hermes, Codex, pack, and per-project outputs are optional export artifacts. Canonical agent-role templates live in
agents/and are materialized project-locally; never create a second hand-maintained plugin skill tree. - Keep Codex plugin metadata, the Hermes Agent-discoverable root catalog, repository URL, and registry synchronized through
scripts/validate.pyand packaging tests. - Increment the plugin semantic version when a distributed plugin change must invalidate an installed cache.
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.
