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 | $0.00033 | $0.01095 |
| Opus 5 | $0.00016 | $0.00548 |
| Sonnet 5 | $0.00007 | $0.00219 |
| Haiku 4.5 | $0.00003 | $0.00110 |
Grade A, and why
decision-rationale-gaps 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 3d 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Press decision
Contract
| Field | Bound contract |
|---|---|
| Trigger | Right after a decision was made, especially one laid out without argument |
| Authority | Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation. |
| Side effect | None (advisory); flags the decision for re-review on an unexplained gap |
| Done | Every closed gap traces to the user's own explanation; open gaps named specifically and carried forward as flags; rationale never supplied by the skill |
Inputs
- Decision text: The decision statement to press. Required. Must be the decision that was made, not the reasoning behind it.
- Context (optional): Any surrounding context about what options were considered and which was picked.
Procedure
- Restate neutrally: State the decision without justification. Do not supply its reasoning or let the user borrow reasoning that was never given. Done when: the decision is restated without justification.
- Isolate the critic: Hand only the decision, without any reasoning, to a fresh session that did not watch the decision get made. Do not pass the optional Context; it carries the reasoning the critic must not see. Instruct it to identify gaps: what a skeptical outsider would challenge, what is assumed but unstated, and what must be true for the choice to hold. Done when: the critic session receives only the decision and returns gap candidates.
- Return one gap: Keep the critic's full response as the candidate pool for the whole press. Extract the single sharpest unresolved gap that no earlier round has extracted. Never batch gaps into a checklist. Each closed gap returns here for the next candidate. When no unextracted candidate remains, the gap loop ends at step 7. Done when: one gap is extracted, or the critic response is empty and the gap is named as unresolved-critic-response, or the pool is exhausted and the loop ends.
- Press the user: Present the current question, the extracted gap or its narrowed form, and ask the user to explain it in their own words. The skill never supplies the rationale. Done when: the current question is presented to the user for their explanation.
- Judge the answer:
- If the answer actually resolves the gap: close it and return to step 3 to extract the next gap from the candidate pool.
- If it restates the question, deflects, or leans on authority ("the agent suggested it"): do not accept it.
What ships with it
1 file 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.

decision-rationale-gaps is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 3d ago), licensed Apache-2.0. It adds 33 tokens to every session and 1,095 once invoked, about $0.0002 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 2026-09-03.
Other skills, from other repositories
audit-project
Run an iterative multi-agent code audit until critical and high findings are resolved. Use when the user says "audit my code", "find all the bugs", "deep code audit", "iterative review", or "review until clean".
duet
Use when the user invokes /duet, says "pair with me", or faces aesthetic, architectural, or irreversible decisions.
goal-prompt-drafting
Use when asked to draft copy-ready /goal objectives for long-running agents; returns one normalized one-line objective with measurable end state, grounded proof, easy-out invariants, a stop clause, and a Missing list. Not for source or remote-system changes.
handoff-prompt
Use when the user asks for a handoff, delegation, or clipboard-ready prompt for another agent: a standalone path-free prompt copied to the clipboard, confirmed by title. Not for session-snapshot briefs — use handoff; never remote, credential, publish, deploy, or irreversible.
publish-branch
Use when asked to publish the checked-out branch: commit and push it on whatever branch it is, the default branch included. Not for creating branches, PRs, force pushes, or pushing any other branch; when the request excludes the default branch, use commit-push-current.
snippet-image-rendering
Use when the user explicitly names snipgrapher and wants code rendered to a polished PNG, SVG, or WebP at an explicit local path. Probes the installed CLI for supported flags and writes only the named image file. Not for other renderers, publishing, or remote actions.
