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 | $0.00019 | $0.00281 |
| Opus 5 | $0.00010 | $0.00140 |
| Sonnet 5 | $0.00004 | $0.00056 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
pebble-stop 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s http://localhost:5173/health || echo "Pebble is stopped." What it actually says
Stop Pebble
The Pebble launcher serves the web app on port 5173. To stop it, kill whatever
holds that port:
lsof -ti:5173 | xargs kill -9 2>/dev/null
Confirm it's down:
curl -s http://localhost:5173/health || echo "Pebble is stopped."
This stops only the Pebble launcher (the web app + /api/* reverse proxy).
It does not:
- touch the Hermes gateway or the API server on
8642— those keep running, - remove the installed plugin at
~/.hermes/plugins/pebble/or the binary at~/.hermes/bin/pebble.
To start Pebble again, see the pebble:pebble-setup skill
(../pebble-setup/SKILL.md) — step 2 also frees the
port before launching, so a fresh start handles a stale process on its own.
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.

pebble-stop is a skill published in the GitHub repository skyf0xx/Pebble (22 stars, last pushed 1mo ago), licensed MIT. It adds 19 tokens to every session and 281 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
