Q00/ouroboros is an Agent OS for running coding agents through interviews, staged evaluation, and repeated improvement cycles. It helps developers turn vague requests into tested code across multiple agent runtimes. Its catalogue add-ons provide workflows, agents, hooks, instructions, and integrations for operating those processes.
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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 5.1 | $0.00080 | $0.03206 |
| Opus 5.5 | $0.00032 | $0.01282 |
| Sonnet 5.5 | $0.00016 | $0.00641 |
| Haiku 4.5 | $0.00008 | $0.00321 |
Grade B, and why
auto scanned grade B with 1 finding 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.

monitoring (below), and never tell the user to call job tools themselves. The How it starts
The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/ouroboros:auto
Run the full-quality auto pipeline from a single task description.
Dispatch requirement
This skill must be executed by invoking MCP tool ouroboros_start_auto. Do not
manually inspect repositories, run shell commands, query GitHub, edit files, or
otherwise emulate the auto pipeline. The background starter returns job_id
and auto_session_id quickly; retain both. If ouroboros_start_auto or a
required job wait/result tool is unavailable, stop and report that the required
MCP tool is unavailable. A manual fallback is not an ooo auto run.
If a started auto job returns detached, blocked, failed, or another
auto-session status, report that status and the tool's blocker. detached is
non-terminal tracked background work: surface the job/Ralph handles and keep
observing them through the same owner. Do not label a blocked or failed
outcome as MCP dispatch failure; dispatch failure means the MCP tool could not
be invoked.
Do not stop after returning the job_id: keep the conversational UX, delegate
monitoring (below), and never tell the user to call job tools themselves. The
user should not have to poll the job manually.
Immediately before each ouroboros_* call, load its schema with the active runtime's tool-discovery capability (for example "+ouroboros auto" for ouroboros_start_auto and "+ouroboros session signal" for the Synapse tools); a schema loaded on an earlier turn may be gone. An empty result for an already-callable tool is expected.
Usage
ooo auto "Build a local-first habit tracker CLI"
ooo auto --resume auto_abc123
ooo auto "Build a local-first habit tracker CLI" --skip-run
/ouroboros:auto "Build a local-first habit tracker CLI"
ooo auto takes no parent Seed and infers no lineage from goal prose (a Seed
named in the goal is ordinary context); never claim preserved lineage or AC
edit scope. Use ooo evolve for parent evolution or ooo run for an existing
Seed.

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.

auto is a skill published in the GitHub repository Q00/ouroboros (6,285 stars, last pushed today), licensed MIT. It adds 80 tokens to every session and 3,206 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
