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.

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 | $0.00051 | $0.01296 |
| Opus 5 | $0.00026 | $0.00648 |
| Sonnet 5 | $0.00010 | $0.00259 |
| Haiku 4.5 | $0.00005 | $0.00130 |
Grade A, and why
doubt-driven 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Doubt-driven development
Contract
| Field | Bound contract |
|---|---|
| Trigger | Non-trivial decision under uncertainty; correctness matters more than speed; a claim not checkable by the type system or compiler; before committing non-trivial code |
| Authority | Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation |
| Side effect | Chat output: fresh-context adversarial review findings and reconciliation |
| Done | Every non-trivial decision named as a CLAIM and fresh-context reviewed; findings classified; a stop condition met |
Inputs
- Artifact (required): the unit under scrutiny: a code diff, function, decision proposal, or assertion plus its supporting evidence.
- Contract (required): the constraint the artifact must satisfy.
Procedure
-
CLAIM. Name the non-trivial decision compactly as
CLAIM: "<statement>"plusWHY THIS MATTERS: <consequence>. A decision that cannot be stated that compactly is a vibe, not a decision; surface it before scrutinizing. Done when: the decision is stated as a compact CLAIM with its consequence. -
EXTRACT. Isolate the smallest reviewable unit: the artifact and the contract, without the reviewer's reasoning. Passing conclusions to the reviewer invites validation of those conclusions. Decompose a 500-line PR first; the unit must fit one read. Done when: the smallest reviewable unit is isolated and fits one read.
-
DOUBT. Spawn a fresh-context subagent with isolated context using this adversarial prompt verbatim so it overrides any default balanced response shape:
Adversarial review. Find what is wrong with this artifact. Assume the author is overconfident. Look for: - Unstated assumptions - Edge cases not handled - Hidden coupling or shared state - Ways the contract could be violated - Existing conventions this might break - Failure modes under unexpected input Do NOT validate. Do NOT summarize. Find issues, or state explicitly that none could be found after thorough examination. ARTIFACT: <paste artifact> CONTRACT: <paste contract>
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.

doubt-driven is a skill published in the GitHub repository OutlineDriven/odin-claude-plugin (35 stars, last pushed today), licensed Apache-2.0. It adds 51 tokens to every session and 1,296 once invoked, about $0.0003 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.
