verify

verify is a skill for Claude Code, Codex from kcdjmaxx/HomarUScc. It costs 83 tokens per session (1,571 once invoked), scanned A, original, MIT.

A document fact-checking workflow that compares claims with specified source files and creates a report showing which claims are correct, incorrect, or unverified.

In plain words
What is it for?
Use it to check reports, experiment results, or other documents against notes, data files, and code, using a verify.md configuration file.
Why use it?
It helps find unsupported or inaccurate statements without requiring you to check every claim manually. It can also apply approved corrections.

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

verify 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 3d 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verify

Automated fact-checking loop that verifies claims in a document against source data. Produces an errata report listing what's correct, incorrect, and unverifiable. Optionally applies corrections.

Usage

/verify                         -- verify target document using ./verify.md config
/verify --report-only           -- produce errata report without applying corrections
/verify --apply                 -- apply corrections from existing errata
/verify <path>                  -- verify a specific file (looks for verify.md in same dir)

Prerequisites

The current working directory (or the target file's directory) must contain a verify.md file with configuration.

verify.md Format

target: RESULTS.md                    # Document to fact-check
sources:                              # Source(s) of truth — prose and/or structured data
  - experiment-log.md                 # Prose source
  - .autoresearch/results-data.json   # Structured data source (authoritative for numbers)
  - eval.py                           # Code source (methodology verification)
errata: ERRATA.md                     # Where to write the errata report
claim_types:                          # What kinds of claims to check
  - numbers                           # Specific numbers, percentages, counts
  - names                             # Names, labels, identifiers
  - methodology                       # Process descriptions, how things were done
  - conclusions                       # Logical conclusions drawn from data
auto_apply: false                     # If true, apply corrections without asking

Source Priority

When a claim can be checked against multiple sources, use this priority:

  1. Structured data (JSON) — authoritative for numerical claims. If results-data.json says consistency=0.8 and experiment-log.md says 1.0, the JSON wins.
  2. Code — authoritative for methodology claims. If the document says "5 runs per experiment" and eval.py shows RUNS=5, the code wins.
  3. Prose sources — for narrative context, conclusions, and interpretations.

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.

verify is a skill published in the GitHub repository kcdjmaxx/HomarUScc (1 stars, last pushed 3mo ago), licensed MIT. It adds 83 tokens to every session and 1,571 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 2026-08-31.
