Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00049 | $0.01525 |
| Opus 5 | $0.00024 | $0.00763 |
| Sonnet 5 | $0.00010 | $0.00305 |
| Haiku 4.5 | $0.00005 | $0.00153 |
Grade A, and why
pr-local-preview-maintainer 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.

PR Local Preview Maintainer
Run pull requests in a disposable local worktree and give the user a stable preview link. The point is to let the user review the PR while protecting their current working tree and making UI changes visible.
Default Workflow
1. Preserve the current workspace
Start by checking the repository state:
git status --short --branch
gh pr view <number> --json number,title,state,headRefName,headRepositoryOwner,url,isCrossRepository
If the current worktree has local changes, do not run gh pr checkout there.
Create or reuse a sibling worktree instead. This avoids overwriting unrelated
work and keeps the PR preview easy to remove later.
Use a predictable path:
<repo-parent>/<repo-name>-pr-<number>
For this repository, PR 8 should become:
/Users/zeeland/projects/rudder-oss-pr-8
If the directory already exists, inspect it before reusing it:
git -C <worktree-path> status --short --branch
git -C <worktree-path> branch --show-current
If it is dirty, ask only if the dirty changes conflict with the user's goal.
Otherwise, pick a suffixed path such as <repo-name>-pr-<number>-preview.
2. Check out the PR in the worktree
Create the worktree from the remote base, then check out the PR branch inside it:
git worktree add --detach <worktree-path> origin/main
gh pr checkout <number> --branch zeelandc/pr-<number>
If main is not the base branch, use the PR's actual base ref. Prefer a local
branch name that makes the preview purpose clear and follows the user's branch
prefix convention when the repository defines one.
After checkout, verify:
git status --short --branch
3. Install dependencies only when needed
Check whether dependencies are present:
test -d node_modules && echo node_modules-present || echo node_modules-missing
If missing, install them from the worktree:
pnpm install
Report install warnings only when they affect the preview. Routine peer or bin link warnings can be mentioned briefly.
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.

pr-local-preview-maintainer is a skill published in the GitHub repository Undertone0809/rudder (288 stars, last pushed today), licensed Apache-2.0. It adds 49 tokens to every session and 1,525 once invoked, about $0.0002 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.
