quaere-grounding

quaere-grounding is a skill for Claude Code, Codex from haru0416-dev/quaere. It costs 144 tokens per session (4,928 once invoked), scanned A, original, MIT.

A fact-checking method for software information that can change, such as library versions, APIs, command-line tools, and security notices.

In plain words
What is it for?
It helps verify package behavior, API names, command options, release changes, deprecations, and affected software versions.
Why use it?
It reduces the risk of relying on outdated or incorrectly remembered technical details by requiring a working check and a second independent source.

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-grounding 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 9d 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.

External Grounding

Iron Law

No claim becomes confirmed without (a) an executable probe AND (b) a lateral corroborator. Otherwise the claim stays inconclusive.

This is not a stylistic rule. Model memory hits only 48–51% on version-conditioned generation and follows internal priors even after retrieval, and single-source acceptance — even of high-authority sources — is the dominant documented failure mode; the gate therefore needs both axes (source quality AND probe + lateral corroboration). The evidence base and the two-axis lineage are in references/source-quality.md.

Boundary with quaere-evidence

quaere-grounding confirms external facts: package versions, SDK method names, API contracts, CLI options, cloud-service behavior, deprecation dates, affected versions, security guidance.

quaere-evidence uses those facts to evaluate claims: whether a reviewer is right, whether a bug cause is confirmed, whether a CI failure is explained, whether a proposed fix closes the risk.

The handoff from this skill should be a set of external constraints. The handoff from quaere-evidence should be a decision about claims, causes, or fixes.

At the time of writing (2026-05), Anthropic's official documentation did not provide guidance for resolving "docs say X / installed types say Y" conflicts. The closest precedent is the claude-api skill's "add alongside, don't replace" rule for version-tied state, which this skill extends.

When to use

  • Library, SDK, framework, runtime, or CLI behavior may have changed.
  • The task depends on official docs, changelogs, release notes, migration guides, deprecation notices, cloud-provider behavior, API schemas, or security advisories.
  • Local code and remote docs appear to disagree.
  • The user says not to trust model memory, asks for current docs, or mentions stale knowledge risk.
  • A security, compatibility, or migration decision depends on affected versions or dates.

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.
