chain-of-verification SKILL.md skillA
chain-of-verification from serpro69/claude-toolbox is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add serpro69/claude-toolbox/chain-of-verification@git:20260605.d0fb1bePins git:20260605.d0fb1be in mdr.lock. Pin the fingerprint instead.

Apply Chain-of-Verification (CoVe) prompting to improve response accuracy through self-verification. Use when complex questions require fact-checking, technical accuracy, or multi-step reasoning.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chain-of-Verification (CoVe)
CoVe is a verification technique that improves response accuracy by making the model fact-check its own answers. Instead of accepting an initial response at face value, CoVe instructs the model to generate verification questions, answer them independently, and revise the original answer based on findings.
## Conventions
- **Read capy knowledge base conventions** at [shared-capy-knowledge-protocol.md](shared-capy-knowledge-protocol.md).
**Capy restriction:** CoVe is a read-only verification tool. Do NOT call `capy_index` or `capy_fetch_and_index` during this workflow. Use `capy_search` only. If corrections reveal knowledge worth persisting, the calling agent handles indexing after CoVe completes.
## When to Use This Skill
CoVe adds the most value in these scenarios:
**Precision-required questions:**
- Questions containing precision language ("exactly", "precisely", "specific")
- Complex factual questions (dates, statistics, specifications)
**Complex reasoning:**
- Multi-step reasoning chains (3+ logical dependencies)
- Technical claims about APIs, libraries, or version-specific behavior
**Fact-checking scenarios:**

How to install
mdr add serpro69/claude-toolbox/chain-of-verification@sha256:d88e796d477649f1The line at the top of this page pins the label git:20260605.d0fb1be, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
