An update command for Ouroboros, the software being managed here. It checks whether a newer version is available and can install it while preserving the existing installation setup.

Use it to check for updates and, after confirmation, upgrade Ouroboros; users of both Claude Code and Codex can refresh both integrations.

It avoids manual upgrade steps and makes the update process follow the tool's configured installation and environment.

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.

Model	Per session	Once invoked
Fable 5	$0.00014	$0.00996
Opus 5	$0.00007	$0.00498
Sonnet 5	$0.00003	$0.00199
Haiku 4.5	$0.00001	$0.00100

Security

Grade A, and why

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 4d 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.

/ouroboros:update

Check for updates and upgrade Ouroboros without changing the installation's manager, environment, or optional-dependency profile.

Usage

ooo update
/ouroboros:update

Trigger keywords: "ooo update", "update ouroboros", "upgrade ouroboros"

Instructions

When the user invokes this skill:

Use the native command as the single source of truth:
```
ouroboros update --check
```
- If it reports up to date, report that result and stop.
- If it reports an update available, ask the user to choose Update now or Skip.
- If the user chooses Update now, run:
```
ouroboros update --yes
```
  When the user actively uses both Claude Code and Codex, refresh both host integrations without changing the configured execution backend:
```
ouroboros update --yes --runtime all
```
Show the command's result. The native updater binds the package upgrade and post-update setup to one receipt-backed installation identity: manager, environment, recorded profile, and environment-local console script.
If the check exits unsuccessfully but ouroboros update --help works, report the native error and stop. Do not replace it with a manual updater. In particular, do not infer ownership from global uv tool list, pipx list, PATH order, directory names, or the active agent runtime.
If ouroboros update --help does not work, this is a legacy installation that predates the receipt-bound updater. Fail closed:
- A read-only ouroboros --version check is allowed.
- Explain that the old skill cannot prove the original manager, environment, and extras/profile, so it will not mutate the installation.
- Ask the user to rerun the exact original install command (including its ouroboros-ai[...] extras and custom manager root) to reach a version with the native updater.
- If the user does not know that identity, recommend a fresh isolated install rather than guessing.
- Do not run package upgrades, plugin refreshes, or setup commands from this legacy path.

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.

update is a skill published in the GitHub repository Q00/ouroboros (5,747 stars, last pushed 2d ago), licensed MIT. It adds 14 tokens to every session and 996 once invoked, about $0.0001 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 2026-08-30.

llm-pipeline

Use when wiring several LLM calls into a production flow: typed contracts between steps, a router/gateway so 429s, timeouts and outages fail over instead of taking you down, and cost control via caching, model tiers and abort caps. NOT single-prompt wording (that is prompt-engineering), NOT a model-driven tool loop…

foundry-config-setup

Resolve missing setup caused by a hardcoded Foundry project endpoint or model in a sample. Use when a sample fails because it uses a placeholder/hardcoded projectendpoint (for example "https://your-project.services.ai.azure.com") or a hardcoded model instead of reading them from the environment.
