ouroboros

ouroboros is a skill for Claude Code, Codex from devswha/oh-my-gajae-code. It costs 42 tokens per session (840 once invoked), scanned A, original, MIT.

An integration with Ouroboros, external software for a specific GJC workflow. It is activated only by the explicit `/omg:ouroboros-setup` command and checks whether a suitable installation is available.

In plain words
What is it for?
Use it to set up or verify the Ouroboros integration within GJC when that exact setup command is requested.
Why use it?
It prevents ordinary planning or implementation work from accidentally changing or installing the external software. It also stops when required prerequisites or a supported updater are missing.

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.

Security

Grade A, and why

ouroboros scanned grade A 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (ouroboros.test.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ouroboros external integration

Ouroboros is upstream-owned external software (ouroboros-ai). This skill is only an explicit GJC integration boundary: never vendor, copy, reconstruct, install, or modify its engine, MCP server, bridge, or its 24 upstream skills. It does not replace or implicitly invoke any GJC native workflow.

Activation and prerequisites

  • Activate only from /omg:ouroboros-setup. Do not activate from ordinary planning, interview, seed, specification, or implementation requests, even when they mention Ouroboros.
  • Require Python >=3.12 and gjc. If the ouroboros executable is absent, report it and stop. For an installed executable, classify legacy updater support first as described below; only a modern updater-supported installation proceeds to ouroboros --version and the minimum Ouroboros 0.51.7 check. Never auto-install, auto-update, or mutate anything automatically.

/omg:ouroboros-setup

  1. Confirm that ouroboros update --help exists. If it is absent, or the install identity is ambiguous, fail closed. State that this may be a legacy or ambiguous install and show the official upstream reinstall command: curl -fsSL https://raw.githubusercontent.com/Q00/ouroboros/main/scripts/install.sh | OUROBOROS_INSTALL_RUNTIME=gjc bash. Do not execute it, offer an automatic repair, or mutate the installation. The user must run it directly, restart or reload GJC, and explicitly invoke /omg:ouroboros-setup again.
  2. For a modern installation, run exactly ouroboros update --check as the only latest-version check. Do not scrape GitHub, query a package registry, or infer package ownership.
  3. Present the update --check result. Update only after the user makes an explicit choice. The sole update command is ouroboros update --yes --runtime gjc.
  4. After a successful update, stop. Require the user to restart or reload GJC before any further Ouroboros activity.
  5. Inspect the live gjc --help output before setup. Ouroboros 0.51.7 requires GJC's --mode rpc transport. If the advertised --mode values do not include rpc, report the GJC/Ouroboros versions as incompatible and stop before setup. Do not treat text, json, or acp as substitutes and do not claim that an installed bridge proves runtime operation.
  6. For a suitable current installation, invoke exactly ouroboros setup --runtime gjc. Use an upstream-supported non-interactive option only when its live ouroboros setup --help output confirms that option. Verify the setup command result and relay its restart/reload guidance. Report setup as configuration success only; actual interview operation remains unverified until a first-turn live call succeeds without a GJC RPC protocol error.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

ouroboros is a skill published in the GitHub repository devswha/oh-my-gajae-code (34 stars, last pushed 17d ago), licensed MIT. It adds 42 tokens to every session and 840 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
