decide

decide is a skill for Codex from OutlineDriven/outline-driven-development. It costs 38 tokens per session (886 once invoked), scanned C, original, Apache-2.0.

A decision workflow that frames a fork, recommends a default when evidence supports one, applies the chosen path, and verifies the result.

In plain words
What is it for?
Use it when choosing between implementation paths and immediately applying the selected option to local work.
Why use it?
It helps turn an unresolved choice into a concrete, reversible change.

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 C, and why

decide scanned grade C 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 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

- User pick contradicts evidence: execute the pick, state the concern once, never re-litigate. Do not refuse a confirmed pick.

Decide

Contract

Field Bound contract
Trigger The user has a fork and wants it resolved and applied, not explored: "help me decide", "just decide this", "what should I do here", or "decide and fix it".
Authority Human-gated: asks before unrecoverable or observable-surface removal; otherwise reversible local, applying the selected change or dispatching the verify/keep/revert loop. No remote mutation.
Side effect Local artifacts only; rollback is git revert or edit revert of the applied change.
Done The fork, user pick, and resulting change are named; the pick is implemented and verified in the same turn.

Inputs

The fork: the decision point the user named, or one surfaced from the code. Optional: the user's stated preference, which becomes the recommended default only if evidence supports it.

Procedure

  1. Confirm that the user wants this fork resolved and applied. Do not use this skill for a verdict of the agent's own making, an exploration that ends in a document, a whole-session director-executor posture, a wide design tree handled in batches, or ambiguity within a stated request. Stop if any of those apply; this skill does not route there. Done when: the fork is confirmed as user-requested and apply-ready, or the run stops with the routing reason stated.
  2. Ground the fork before framing it. Resolve from evidence first with grep, glob, read, or lsp. A fork the code already answers is not a fork: read it, say what it answers, and do not ask. Never ask what a search settles. Done when: the fork is grounded from evidence or resolved as already-answered by the code.
  3. Frame one single-select per axis. Give two to four options, placing (Recommended) first and stating its consequence in the description. Each option names what the code looks like afterward. Where two options differ visibly, put the difference in preview as a diff or tree. Never use multiSelect for override semantics. Done when: one single-select per axis is framed with the recommended option first and consequences stated.
  4. Take the pick and act in the same turn. A pick applied in one edit gets the edit. A pick needing a verify, keep, or revert loop is restated as its goal and executed as that loop. A pick that removes an observable surface or cannot be reverted from git gets one concern stated, then a yes. Done when: the pick is applied as an edit, loop, or gated action in the same turn.
  5. When applying one pick opens the next fork, ask it immediately with the settled decision restated in one line. Never bank a queue of questions to fire at the end. Done when: the next fork is asked immediately or no next fork exists.
  6. When the user picks what the agent would not: execute the pick, state the concern once, never re-litigate. Done when: the pick is executed with one concern stated and no re-litigation.
  7. Close with one line naming the fork, the pick, and what changed. Done when: one closing line names the fork, pick, and resulting change.

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.
