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 | $0.00055 | $0.03608 |
| Opus 5.5 | $0.00022 | $0.01443 |
| Sonnet 5.5 | $0.00011 | $0.00722 |
| Haiku 4.5 | $0.00006 | $0.00361 |
Grade A, and why
opencodehub-guide 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 2mo 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 — 262 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenCodeHub Guide
Quick reference for every OpenCodeHub MCP tool, MCP resource, and the single-file store.sqlite schema.
Always Start Here
For any task that touches code understanding, debugging, impact analysis, refactoring, or PR review:
- Call
mcp__codehub__list_repos— confirm the repo is indexed and pick areponame. - Read
codehub://repo/{name}/context— codebase stats and a staleness envelope. - Match the task to a skill below and follow that skill's checklist.
If the context envelope reports the index is stale, run
codehub analyzein the terminal first. If it says weights are missing, runcodehub setup --embeddingsto fetch the 320d F2LLM-v2-80M ONNX weights.

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.

opencodehub-guide is a skill published in the GitHub repository theagenticguy/opencodehub (3 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 55 tokens to every session and 3,608 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
