Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00514 |
| Opus 5 | $0.00015 | $0.00257 |
| Sonnet 5 | $0.00006 | $0.00103 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
verify-refs 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 yesterday.
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 — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/verify-refs — Reference Authenticity Check
Running Python helpers
Choose the interpreter before running the examples. For a globally installed
copy, use the private runtime recorded by its installer. In a checkout or linked
workspace, use AWT_PYTHON when set, otherwise the toolkit's .venv (follow the
skill directory link back to the toolkit): Scripts/python.exe on Windows,
bin/python on macOS/Linux. Without that environment, check that python
(Windows) or python3 (macOS/Linux) actually runs and has the helper's dependencies.
Replace the example's python3 with that executable. In PowerShell, prefix a
quoted executable with &; keep commands on one line and quote file paths.
Purpose
Check reference records for missing required fields, duplicate keys, malformed DOI values, malformed arXiv identifiers, and invalid URLs. The default mode is offline and deterministic.
Trigger Words
This skill activates on: verify refs, verify references, reference check, /verify-refs.
Workflow
- Identify the target Markdown or
.bibfile. If the user does not specify one, ask. - Run:
python3 .claude/skills/verify-refs/scripts/verify-refs.py --bib "{path}" --json - Report issues by entry key and severity.
- For explicit metadata verification, run:
python3 .claude/skills/verify-refs/scripts/verify-refs.py --bib "{path}" --json --online - Use CrossRef for DOI metadata, Semantic Scholar as a secondary metadata source, and arXiv for preprint identifiers. Online checks must be explicit because they depend on network availability.
- In tests or offline review, use
--metadata-dir "{dir}"to read CrossRef JSON, Semantic Scholar JSON, and arXiv Atom fixtures instead of live network calls.
Constraints
- Do not import project-specific reference rules from other repositories.
- Do not auto-fix reference records without user approval.
- Keep output plain Markdown with no emoji.
- Treat CrossRef, Semantic Scholar, and arXiv as verification sources, not as citation style authorities.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-refs is a skill published in the GitHub repository yha9806/academic-writing-toolkit (37 stars, last pushed 2d ago), licensed MIT. It adds 29 tokens to every session and 514 once invoked, about $0.0001 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 2026-08-30.
