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 | $0.00918 |
| Opus 5.5 | $0.00024 | $0.00367 |
| Sonnet 5.5 | $0.00012 | $0.00184 |
| Haiku 4.5 | $0.00006 | $0.00092 |
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 4d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Query Handigraphs Stats
Connection
This plugin connects to the hosted Handigraphs MCP server at
https://mcp.handigraphs.com/mcp, available to eligible Handigraphs All Access members.
Use only this plugin's handigraphs-stats-hosted connection;
never silently switch connections, identities or local credentials following
an OAuth failure.
Sign in through the client's browser OAuth flow as the intended Handigraphs account. Never ask for, accept or repeat an API key, website JWT, access/refresh token or service secret in chat, tool arguments, headers or configuration. No local key setup helpers are included. The client discovers public registration and authorization metadata; do not ask users to register a confidential client.
stats:read is required; filters:write and research:run are independent opt-in
consent choices. A connection grants only approved scopes and current eligibility,
Terms, rollout and worker policy still apply. For 401 or revoked/expired consent,
use the client's reconnect/login flow. For missing scopes, explain the denial;
the owner can revoke the app at /account/api and reconnect with explicit consent.
Never approve broader scopes automatically. A lapsed account can still inspect
and revoke connections. Do not fall back to an API key or another account to
bypass policy, quotas, errors or an unavailable worker. Switching to local is a
separate user choice; the existing local installation and keys remain supported.
Shared business workflow
Use live discovery instead of guessing resource, metric, split, unit, or filter names.
For native saved filters, Angles historical tests, or research-and-save requests,
use the bundled research-handigraphs-filters skill. Its rules and units differ
from the simple numeric query filters below. The agent tools can save account
items and submit research when authorized; ordinary stats queries remain read-only.
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.
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 4d ago), licensed Apache-2.0. It adds 61 tokens to every session and 918 once invoked, about $0.0002 per session on Opus 5.5. 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.
