# /verify-claim — Research Rigor Enforcement
**Purpose**: Stop unverified factual claims (counts, names, versions, dates, quotes) from reaching the reader. Verify or mark `[unverified]` — never guess, never interpolate.
## When to Run
- Before publishing any research memo, strategy doc, or competitive analysis
- After drafting a section that contains numbers, names, or versions
- When asked to "fact-check" or "verify" any output
- Proactively during long-form analysis sessions, every ~500 words
## Inputs
- A draft (file path, pasted text, or current conversation output)
- Optional: list of primary sources to check against (repo paths, URLs, docs)
## Process
### 1. Extract Claims
Parse the draft and produce a numbered list of every **factual assertion**. A factual assertion is anything where wrong = wrong, not opinion. Includes:
- Counts (e.g., "9 agents", "3 repos", "187 commits")
- Named entities (people, products, repos, commands, files, libraries)
- Versions (model IDs, package versions, dates)
- Direct or indirect quotes
- Causal claims about specific events ("this broke because X")
Skip: opinions, recommendations, hypotheticals.
### 2. Verify Each Claim
For each claim, attempt verification in this order:
1. **Repo evidence** — `grep`, file `Read`, `git log` for claims about code/commits/configs
2. **Live source** — `WebFetch` for claims about external URLs/APIs/docs
3. **Authoritative reference** — official docs (use `context7` MCP for library/SDK claims)
4.
