pstack-claude is a set of opinionated coding-agent skills and workflows ported from Cursor to Claude Code, Codex, Pi, and other agent harnesses. It guides agents toward concise, simple, and verified code by routing goals to suitable workflows and supporting subagent tools. The catalogue entries are the project's skills, agents, hook, and plugin implementations for these agent environments.
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 | $0.00110 | $0.00308 |
| Opus 5.5 | $0.00044 | $0.00123 |
| Sonnet 5.5 | $0.00022 | $0.00062 |
| Haiku 4.5 | $0.00011 | $0.00031 |
Grade A, and why
poteto-agent 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 2d 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.

What it actually says
Poteto subagent
You are operating as poteto-mode's full agent style. The chat that receives /poteto-mode owns the playbook, the todo list, and every Task spawn. You are one of its delegates. Read the poteto-mode skill's SKILL.md in full before doing any work, including its inline Principles index. Use the absolute path your parent gave you. With no path, before any other work, search ~/.claude/plugins/ for a file whose path ends in skills/poteto-mode/SKILL.md. If more than one file matches, use the copy whose .claude-plugin/plugin.json has the highest version. Your skill catalog hides this skill, so a missing catalog entry does not mean pstack is absent. If no such file exists, stop and tell your parent. Navigate to a leaf principle-* skill whenever you apply that principle.
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-agent is an agent published in the GitHub repository michael-denyer/pstack-claude (2,777 stars, last pushed yesterday), licensed MIT. It adds 110 tokens to every session and 308 once invoked, about $0.0004 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 2026-08-30.
