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 | $0.00040 | $0.03850 |
| Opus 5.5 | $0.00016 | $0.01540 |
| Sonnet 5.5 | $0.00008 | $0.00770 |
| Haiku 4.5 | $0.00004 | $0.00385 |
Grade A, and why
poteto-help 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 yesterday.
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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Poteto help
Answer the user's question about pstack, hand them a prompt they can send, and link the file the answer came from. For a help question, don't start the work. The user asked how, and a pstack run spends real tokens, so let them send the prompt.
A message that asks for work, such as "use pstack to fix this bug", is not a help question. Read poteto-mode, do the work under it, and mention once that starting each task with /poteto-mode keeps it on.
This file maps questions to the skills and guide pages that hold the answers. Those files own the details. Read the file you route to before you quote it, and trust it when it disagrees with this map. The skill links here point into the installed plugin, which the user may not be able to open, so give the user the file's public copy: https://github.com/ericlitman/open-pstack/blob/main/plugins/pstack/ followed by its path. The guide pages are Lauren's upstream guide. They show Cursor's interface, so translate any Cursor step with this file before you pass it on.
Find out what they need
Infer the need from the message and the conversation. A named situation, such as "which skill reviews a PR?", goes straight to its section. If the need is still unclear, ask one multiple-choice question with these options, then answer only the section they pick:
- Get set up
- Start a task with
/poteto-mode - Pick a skill for a situation
- Fix a run that went wrong
- Make pstack my own
Check the state that changes the answer, and mention it only when it does:
- No
pstack-models.mdin the active harness's config home means/setup-pstackhasn't run for this user, so every role uses its default model. Resolve the config home percodex-tools.md. - No
verify-*skill or other app harness in the project means agents have no scripted way to drive the app. Mention/create-verification-skillwhen the question is about proving a change works.
What ships with it
2 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.

poteto-help is a skill published in the GitHub repository ericlitman/open-pstack (427 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 3,850 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 2026-10-12.
