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.

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 | $0.01091 |
| Opus 5.5 | $0.00024 | $0.00436 |
| Sonnet 5.5 | $0.00012 | $0.00218 |
| Haiku 4.5 | $0.00006 | $0.00109 |
Grade A, and why
babysit 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 14d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Babysit a PR
On Codex, read the platform mapping, including its per-skill notes, before following this skill.
On GitHub Copilot, read the platform mapping, including its per-skill notes, before following this skill.
Claude Code analog of Cursor's built-in /babysit. The implementation is a loop over gh CLI plus the Claude Code loop skill for pacing.
Inside poteto-mode, the Babysit playbook (../poteto-mode/playbooks/babysit.md) supersedes this skill: it owns mode declaration, the merge frontier, stack safety, and the watch-pr watcher. This skill stays the standalone /babysit entry point for a single PR outside a poteto-mode run.
When to use
- There's an open PR and the user explicitly wants it kept green, and you are not already inside a poteto-mode run (the playbook owns that case).
- The user invokes
/babysitdirectly. - A subagent that opens a PR does NOT babysit — return to the parent and let the parent decide.
Steps
-
Fetch PR state.
gh pr view <number> --json number,title,state,mergeable,reviewDecision,statusCheckRollup,mergeStateStatus,comments,reviews -
Triage in priority order.
- Merge conflicts (
mergeStateStatus == DIRTY): run the fix-merge-conflicts skill. Force-push only if the branch is yours and not shared. - Failing checks (
statusCheckRollupentries withconclusion: FAILURE): run the fix-ci skill. Root-cause the failure; fix the underlying code or test; commit; push. - Review comments: run the get-pr-comments skill for the summary, then act only on feedback you actually agree with. When a comment has a single mechanical answer — a rename, a guard clause, a formatting nit — make the edit and quote the comment in the commit message. When it hinges on a judgement call, or you can't tell what's being asked, don't guess: leave it and reply with what you would have done.
- Review-bot comments (Bugbot and similar automation): classify fix/dismiss/ask before acting, per
bugbot-triage.md. Ask by default on security, data, and high-severity findings.
- Merge conflicts (
What ships with it
1 file 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.

babysit is a skill published in the GitHub repository michael-denyer/pstack-claude (3,082 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 1,091 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 2026-08-30.
