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 | $0.00062 | $0.00710 |
| Opus 5 | $0.00031 | $0.00355 |
| Sonnet 5 | $0.00012 | $0.00142 |
| Haiku 4.5 | $0.00006 | $0.00071 |
Grade A, and why
manage-agent-config 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 11d 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.

Managing Claude ↔ Codex skills and subagents in this repo
This repo is dual-tool. Before you create or edit anything under .claude/, .agents/, or .codex/, read this and the detailed rule at .claude/rules/codex-claude-sync.md.
Decision tree
Creating a new skill?
- Does it need Claude-only features (
allowed-tools,$ARGUMENTS,!`shell`preprocessing,${CLAUDE_SKILL_DIR})?- Yes →
.claude/skills/<name>/SKILL.md(real directory, no symlink). Claude-only. - No →
.agents/skills/<name>/SKILL.md. Shared;make sync-agent-configcreates the.claude/skills/<name>symlink.
- Yes →
Creating a new subagent?
- Always edit
.claude/agents/<name>.md(markdown + YAML frontmatter). That is the source of truth. .codex/agents/<name>.tomlis generated - never hand-edit.- Run
make sync-agent-config- the TOML appears.
Renaming or deleting?
- Rename or delete the source file (under
.agents/skills/or.claude/agents/). - Run
make sync-agent-config- stale symlinks and orphaned TOMLs are pruned automatically.
Frontmatter rules for shared skills
.agents/skills/<name>/SKILL.md must only use:
name(required, lowercase-hyphens, ≤64 chars)description(required, ≤250 chars - Codex and Claude use this for implicit matching)- Plain markdown body
Do not use any of these in a shared skill:
allowed-tools,disable-model-invocation,user-invocable,context,agent,model,effort,hooks,paths,shell,argument-hint$ARGUMENTS,$1…$N,${CLAUDE_SKILL_DIR},${CLAUDE_SESSION_ID}substitutions!`cmd`or```!shell preprocessing blocks
All of those are Claude-only. In Codex they pass through literally and confuse the model. If you need them, make the skill Claude-only (see decision tree above).
Subagent format notes
Claude .md frontmatter keys that don't exist in Codex (tools, model, color) are preserved as TOML comments in the generated .codex/agents/<name>.toml for human reference. They do not affect Codex behavior. If tool restrictions matter to the agent's job, describe them in the prose body so both tools read them.
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.
- 11d ago First seen · 52 lines · 62 tokens per session scan A 7f5bc287cc77
manage-agent-config is a skill published in the GitHub repository Edison-Watch/sealgate-mcp (0 stars, last pushed 6d ago), licensed MIT. It adds 62 tokens to every session and 710 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
