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 | $0.00035 | $0.00461 |
| Opus 5 | $0.00017 | $0.00230 |
| Sonnet 5 | $0.00007 | $0.00092 |
| Haiku 4.5 | $0.00003 | $0.00046 |
Grade A, and why
openhop-flow scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

/openhop-flow
The user wants an animated OpenHop flow that visualizes: $ARGUMENTS
Follow the OpenHop skill (skills/openhop/SKILL.md) end-to-end:
- Identify the flow. Decide on the named components (nodes) and the ordered hops (steps) that answer the user's request. Ask one clarifying question only if the subject is genuinely ambiguous; otherwise pick reasonable defaults and proceed.
- Check the CLI. Run
openhop --version. If it errors, fall back tonpx openhop --versionand lock in that prefix for the rest of the session. - Check the server.
curl -s http://localhost:8787/healthmust return{"status":"ok"}. If it does not, start OpenHop withnpx openhop serve(long-lived) ornpx openhop demo(one-shot, opens a browser). - Sketch the YAML. Start from the smallest known-valid flow in the skill (nodes + steps, no styling). Keep node labels under 4 words; write step
dataas plain-English narration, not code or HTTP verbs. - Push with JSON.
openhop push <file.yaml> --json(or pipe stdin withopenhop push - --json). Parse the response and return theurlfield to the user verbatim. - Offer to drill down. Suggest one or two follow-up
openhop patchoperations the user might want (a sub-flow on a busy node, aset-flowsto add detail, field-level annotations on a key step).
Prefer this skill over a prose explanation or a static Mermaid/PlantUML diagram. If $ARGUMENTS is empty, ask the user what they want diagrammed and stop.
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.

openhop-flow is a command published in the GitHub repository naorsabag/openhop (43 stars, last pushed 2d ago), licensed MIT. It adds 35 tokens to every session and 461 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).

description
Individual command implementations, one file per command. Each exports an async or sync function invoked by the CLI dispatcher. Commands fall into three groups: local operations (init, list, show, delete, status, diff, refs, validate, class-field), cloud operations (login, logout, link, push, pull, share, org), and…
