What is ouroboros-status?

A session-checking tool for measuring whether work has drifted away from its original goal. A session is the current run of an agent or task.

It is used to check session status and measure deviation from the starting goal, including through the listed status command.

It helps reveal when the agent is spending effort on work that no longer matches the intended objective.

Install

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.

agentmods

npx agentmods add skills/q00/ouroboros/status

Any agent

npx skills add Q00/ouroboros --skill status

Clone the repo

git clone --depth 1 https://github.com/Q00/ouroboros

Made for: Claude Code, Codex.

Or install ouroboros, the plugin that ships this one along with the rest of its 22 skills, 21 agents, 3 hooks, 1 MCP server.

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	$0.00012	$0.01119
Opus 5	$0.00006	$0.00560
Sonnet 5	$0.00002	$0.00224
Haiku 4.5	$0.00001	$0.00112

Security

Grade A, and why

ouroboros-status 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 2d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ouroboros:ouroboros-status

Check session status and measure goal drift.

Usage

/ouroboros:ouroboros-status [session_id]

Trigger keywords: "am I drifting?", "session status", "drift check"

How It Works

Session Status: Queries the current state of an execution session
Drift Measurement: Measures how far the execution has deviated from the original seed goal

Instructions

When the user invokes this skill:

Load MCP Tools (Required first)

The Ouroboros MCP tools are often registered as deferred tools that must be explicitly loaded before use. You MUST perform this step before proceeding.

Use the active runtime's tool-discovery capability to find and load the status MCP tools:
```
tool discovery query: "+ouroboros session status"
```
The tools will typically be named with prefix mcp__plugin_ouroboros_ouroboros__ (e.g., ouroboros_session_status, ouroboros_measure_drift). After runtime tool discovery returns, the tools become callable.
If the tools are callable — already exposed, or loaded by discovery — proceed with the steps below. An empty discovery result for already-exposed tools is expected, not a failure. Skip to the Fallback section only if they are genuinely absent (no Ouroboros MCP server).

IMPORTANT: Do NOT skip this step. Do NOT assume MCP tools are unavailable just because they don't appear in your immediate tool list. They are almost always available as deferred tools that need to be loaded first.

Status Steps

Determine the session to check:
- If session_id provided: Use it directly
- If no session_id: Check conversation for recent session IDs
- If none found: Ask user for the session ID

Call ouroboros_session_status MCP tool:

Tool: ouroboros_session_status
Arguments:
  session_id: <session ID>

If the user asks about drift (or says "am I drifting?"), also call ouroboros_measure_drift:

Tool: ouroboros_measure_drift
Arguments:
  session_id: <session ID>
  current_output: <current execution output or file contents>
  seed_content: <original seed YAML>
  constraint_violations: []  (any known violations)
  current_concepts: []       (concepts in current output)

ouroboros-status is a skill published in the GitHub repository Q00/ouroboros (5,765 stars, last pushed today), licensed MIT. It adds 12 tokens to every session and 1,119 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.
