Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00014 | $0.00236 |
| Opus 5 | $0.00007 | $0.00118 |
| Sonnet 5 | $0.00003 | $0.00047 |
| Haiku 4.5 | $0.00001 | $0.00024 |
Grade A, and why
maestro-update 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 5d 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
Update Maestro to the latest Codex marketplace code. This refreshes the configured Git marketplace and reinstalls the Maestro plugin from it.
When the user invokes this skill, run:
codex plugin marketplace upgrade maestro
codex plugin add maestro@maestro
The update is idempotent. It will:
- Pull the latest Maestro source from the repository.
- Refresh the installed Maestro plugin cache.
- Refresh bundled Codex skills and hooks exposed by the plugin.
- Leave project-local configuration (state files, secrets) untouched.
Notes
- Requires the Codex CLI on
PATH. - After reinstalling, restart the Codex session or open a new thread so updated skills and hooks take effect.
- If the marketplace is not configured yet, run
codex plugin marketplace add mbanderas/maestrofirst. - Portable/manual installs can still be refreshed with
npx github:mbanderas/maestro install --target codexfrom the project root.
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.

maestro-update is a skill published in the GitHub repository mbanderas/maestro (5 stars, last pushed yesterday), licensed MIT.
