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.

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 | $0.00061 | $0.00523 |
| Opus 5 | $0.00030 | $0.00262 |
| Sonnet 5 | $0.00012 | $0.00105 |
| Haiku 4.5 | $0.00006 | $0.00052 |
Grade A, and why
query-handigraphs-stats 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 8d 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 — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Query Handigraphs Stats
Use live discovery instead of guessing resource, metric, split, unit, or filter names.
Workflow
- Call
list_resourceswhen the sport or resource is uncertain. - Call
describe_resourcebefore a query unless the exact live metric, split, and filter contract is already present in the current conversation. - Call
query_statswith one resource and a focused metric projection. Prefer compact output for comparisons; request standard output when performance tiers or sample qualification matter. - Continue pagination only by passing the returned cursor back to
query_statswith the same filters and sort. - State the split, relevant filters, and
data_as_ofvalue when summarizing results.
Query rules
- Use canonical units returned by discovery. A proportion such as 20% is normally passed as
0.20, not20. - Use only
eq,ne,gt,gte,lt, orltefor numeric filters, with no more than five filters. - Keep one split per query. Do not invent historical dates, archive selectors, custom ranges, or unsupported operators.
- Prefer stable entity IDs for follow-up lookups when the API returns them.
- Keep payloads focused. Request rich stats or full metadata only when benchmark details are necessary.
Interpretation
- Treat performance tiers as metric-specific classifications, not universal rankings.
- Report low-sample or unqualified rows clearly rather than presenting them as equally reliable.
- Do not replace a null freshness timestamp, metric value, or tier with an estimate.
- Separate the API result from any analysis or recommendation derived from it.
Errors and credentials
- Never ask for or repeat a Stats API key in chat. If the local server is not configured, invoke the bundled
setup-handigraphs-stats-apiskill and follow its platform-specific masked setup workflow. Do not accept the key as a tool argument or automate entry into the setup window. - Do not automatically retry
429or503responses. Report the safe error code and honor any retry guidance returned by the tool. - Treat every tool as read-only. Do not imply that the plugin can modify Handigraphs data or account settings.
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.

query-handigraphs-stats is a skill published in the GitHub repository Handigraphs/handigraphs-stats-api-mcp (0 stars, last pushed 5d ago), licensed Apache-2.0. It adds 61 tokens to every session and 523 once invoked, about $0.0003 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.
