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.

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 | $0.00011 | $0.00326 |
| Opus 5 | $0.00005 | $0.00163 |
| Sonnet 5 | $0.00002 | $0.00065 |
| Haiku 4.5 | $0.00001 | $0.00033 |
Grade A, and why
repo 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 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.
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
repo Skill
Purpose
Use this skill when Mythos is working inside a real project repository and must preserve the shape of the existing system.
Read First
- README.md
- CHANGELOG.md
- package.json
- src/cli.ts
- src/commands/
- src/commands/swd.ts
- src/swd.ts
- src/security-policy.ts
Rules
- Follow the current architecture and naming conventions before adding new patterns.
- Keep edits scoped to the requested behavior.
- Do not change public CLI flags, package scripts, CI, deploy files, or secret-handling files unless the task explicitly requires it.
- Prefer small, reviewable changes over broad refactors.
- Preserve dry-run behavior for every command that can write files.
- Treat
mythos swd applyas the external-agent execution boundary: no model calls, fail-closed path checks, and JSON-safe output for automation.
Verification
- If the task affects CLI behavior, suggest the narrowest command the maintainer should run.
- If the task affects external-agent SWD behavior, include
mythos swd apply --stdin --jsoncoverage or an equivalent test. - If tests or builds cannot be run safely, state that clearly and name the exact check to run manually.
- Treat SWD receipts as the audit record for any successful filesystem mutation.
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.

repo is a skill published in the GitHub repository thewaltero/mythos-router (300 stars, last pushed today), licensed MIT. It adds 11 tokens to every session and 326 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.
