exhaustive

exhaustive is a skill for Codex from OutlineDriven/outline-driven-development. It costs 77 tokens per session (1,255 once invoked), scanned A, original, Apache-2.0.

A coverage audit that enumerates every case in a bounded state, decision, requirement, or behavior space.

In plain words
What is it for?
It is for finding gaps in specifications, code behavior, designs, refactors, deletions, and other finite scopes that need completeness review.
Why use it?
It exposes missing or postponed cases instead of relying on a general claim that coverage is complete. The result classifies each case and records a check and tally.

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 A, and why

exhaustive 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 5d 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.

Exhaustive

Contract

Field Bound contract
Trigger The user says "exhaustive", "prove coverage", "did I miss any case", "enumerate the state space", or asks for a completeness audit before done.
Authority Reversible-local: read-only on the target source; the only write is the coverage manifest artifact, whose rollback is discarding or deleting that file.
Side effect Writes one classified coverage manifest (human-readable or exhaustive-manifest/v1 YAML) with gaps prepared in dependency order; no source, VCS, config, or remote mutation.
Done The manifest has zero unclassified cells and a one-line tally; for code state spaces the wildcard-catch-all assertion holds.

Inputs

  • Must be supplied: the target surface to audit — a code area, a spec or feature, a design with open forks, or a refactor/deletion scope.
  • Optional: a request for machine-readable exhaustive-manifest/v1 output; user-applied fixes to individual gap cells (each triggers exactly one re-enumeration).
  • If the target space is unbounded or unidentifiable after one read, stop and ask one question to bound it; do not enumerate an infinite space.

Procedure

  1. Choose and name the enumeration that fits the target; restate the choice in the output so the reader knows which space was covered:

    • State space — code with lifecycle, state machines, or error paths: the State × Event × Outcome Cartesian matrix.
    • Decision space — a design with open forks: the dependency-respecting set of decision axes.
    • Requirement space — a spec or feature: the requirement-to-symbol map, each acceptance criterion traced to a code or test symbol.
    • Behavior surface — a refactor or deletion: every exported symbol and reachable path in scope.

    Enumeration is algorithmic and single-pass; it is not round-based questioning or hypothesis sampling. Done when: the enumeration type is chosen, named, and restated.

  2. Enumerate the full cell list for the chosen space with tool-backed discovery: structural search for code constructors and match arms, reference search for symbols and callsites, direct reads for spec criteria. Every cell carries an id and a one-line description. The list is the universe: nothing outside it is in scope, and nothing inside it may be silently dropped. Done when: the full cell list is enumerated with every cell carrying an id and description.

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.

exhaustive is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 3d ago), licensed Apache-2.0. It adds 77 tokens to every session and 1,255 once invoked, about $0.0004 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.
