quaere-execution

quaere-execution is a skill for Claude Code, Codex from haru0416-dev/quaere. It costs 130 tokens per session (3,642 once invoked), scanned A, original, MIT.

A workflow for carrying out multi-step coding changes with explicit planning, implementation, study of the result, and verification. It requires evidence from targeted checks and a reviewed change set before claiming success.

In plain words
What is it for?
Use it to implement features, fix confirmed bugs, refactor code, add tests, or apply review feedback while tracking scope and verification.
Why use it?
It reduces implementation drift and prevents declaring a task complete without confirming that the changes match the request.

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

quaere-execution 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 6d 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 — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Execution Loop

Iron Law

No implementation success claim without fresh verification evidence and a reviewed diff that maps every changed line to the authorized scope.

This is not a paperwork rule. Implementation drift usually happens after the edit: the agent sees a green-looking result, forgets which requirement justified each change, and declares done before studying the actual diff. The loop is Plan → Do → Study → Act: predict what will prove the unit, make the smallest scoped edit, compare the observed result to the prediction, then either fix, split, or hand off. A passing broad suite is useful, but it does not replace the targeted check or the scope review.

When to use

  • The user asks to implement, build, finish, apply a plan, execute a TODO list, refactor, add tests, or address review feedback.
  • The work has more than one meaningful step, touches several files, or needs targeted and final checks.
  • A confirmed claim from quaere-evidence, constraints from quaere-grounding, or invariants from quaere-semantic are ready to implement.

When NOT to use

  • Trivial one-line edits, typo/format-only changes, pure explanations, or single command requests.
  • Unclear bugs, flaky tests, risky review claims, security-sensitive causes, or production-side effects whose cause is not confirmed; use quaere-evidence first (or the quaere-audit extension for property-driven security work, if installed).
  • Current SDK/API/CLI behavior that has not been anchored; use quaere-grounding first.

Handoff triggers (when to switch out)

Stop and hand off when the blocker is no longer implementation:

  • Cause of a failing test or regression is unclear → quaere-evidence.
  • Implementation depends on current SDK / API / CLI / cloud / advisory behavior that is not yet anchored → quaere-grounding.
  • Existing module intent or invariants are unclear → quaere-semantic.
  • Security properties or auth / tenancy / parser / concurrency / crypto / payment / sandbox risks come up → stop before patching beyond a confirmed fix. If the quaere-audit extension is installed, hand off to it; otherwise flag the security risk and escalate to the user.

Changes

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.
