What it costs to keep this loaded
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 | $0.01208 |
| Opus 5 | $0.00030 | $0.00604 |
| Sonnet 5 | $0.00012 | $0.00242 |
| Haiku 4.5 | $0.00006 | $0.00121 |
Grade A, and why
stop-rudder-dev-maintainer 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 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.
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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stop Rudder Dev Maintainer
Keep Rudder local dev runtime maintenance tight and safe.
The job is usually simple:
- identify the current Rudder dev runtime processes
- stop them gracefully
- confirm whether anything was actually running
Do not broaden that into generic process cleanup for the whole machine. Port ownership alone is never sufficient evidence that a process belongs to this checkout.
Fast Applicability Check
Before doing any process or port investigation, classify the user's current task:
- Use the full workflow when the task is about the repo-local development
runtime, such as stopping or restarting
pnpm dev. - If the task is mainly about production/local-prod data, packaged Desktop, organizations, database cleanup, backups, migrations, or API maintenance, this skill is not the main workflow. Do not spend time inspecting broad process lists for those tasks.
- If the user explicitly included this skill as a safety preflight for a
non-dev task, run only the bundled script once, report whether it found a
pnpm devruntime, and move on.
Packaged Desktop, pnpm prod, pnpm rudder run, and embedded Postgres owned by
/Applications/Rudder.app are out of scope. Leave them running unless the user
explicitly asks to stop the production/local-prod runtime.
If the bundled script cannot prove that a process is a dev entrypoint for the
current checkout, leave it running. Do not compensate with a manual kill
based on a port, process name, or repo working directory alone.
Scope
This skill is only for the current Rudder checkout.
It is designed around the repo-root development flow:
pnpm dev
That flow launches scripts/dev-shell.mjs, which in turn manages the local dev runner and desktop shell.
The dev shell must discard any inherited prod_local runtime identity before
startup, and the dev runner must refuse to take over a runtime owned by
Desktop, CLI, or a standalone server. If either invariant fails, stop and fix
the startup path; do not use this skill's stop script as a workaround.
The dev runner must also refuse to start against the protected prod_local /
default target even when no production runtime is currently healthy.
What ships with it
3 files 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.

stop-rudder-dev-maintainer is a skill published in the GitHub repository Undertone0809/rudder (288 stars, last pushed today), licensed Apache-2.0. It adds 61 tokens to every session and 1,208 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 2026-08-30.
