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 | $0.00257 | $0.00257 |
| Opus 5.5 | $0.00103 | $0.00103 |
| Sonnet 5.5 | $0.00051 | $0.00051 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
doubt AGENTS.md 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 1mo 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
Contributor guide
Scope
Doubt is a zero-dependency Node.js CLI plus a portable Agent Skill. Keep the core local-first, provider-independent, and fail-closed on source traceability.
Commands
npm test— run the Node test suite.npm run lint— syntax-check executable source files.npm run check— run all release checks.npm run demo— render the public dogfood evidence map.node bin/doubt.js validate examples/agent-skills-vs-mcp.doubt.json— inspect the canonical example.
Design constraints
- Support Node.js 18 and later with built-in modules only.
- Never execute installed skill or map content.
- Never upload user text, source content, or telemetry. Only the explicit
doubt verifycommand may retrieve recorded source URLs; all other commands stay offline andverifymust fail closed. - Treat
skill/doubt/as the canonical install payload. - Escape all user-controlled text before embedding it in HTML.
- Add passing and adversarial fixtures for every schema invariant.
- Prefer a specific unknown over a confidence percentage.
- Never turn topical similarity into a
supportsedge.
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.
