What is ess-pr-review?

An assisted review workflow for one or more GitHub pull requests. It runs the project's own checks for issues such as lint errors, repeated code, security, and performance, then examines broader correctness before showing findings for approval.

Use it to review pull-request changes, check code quality and security concerns, assess cross-file behaviour, and publish selected findings.

It separates routine checks from questions that require reading the change in context. Nothing is posted to a pull request until you approve the results.

Token cost

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	$0.00160	$0.03517
Opus 5.5	$0.00064	$0.01407
Sonnet 5.5	$0.00032	$0.00703
Haiku 4.5	$0.00016	$0.00352

Security

Grade A, and why

ess-pr-review 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.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/create-review-worktree.sh, scripts/find-review-requests.sh, scripts/lib.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 291 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review PR

Review one or more GitHub Pull Requests. Linters find, the LLM judges: a scan script runs the repo's own linters over each PR diff and emits a compact report, so you spend attention on correctness, cross-file logic, and disable-comment justification — not on re-deriving lint findings token by token.

This skill is variadic: it always operates on a set of PRs of size N ≥ 1. A single PR is just N = 1 and uses a fast in-place path; multiple PRs each get an isolated read-only worktree. Nothing is posted to any PR until you approve at one gate.

Phase: Review

Quick start

/ess-pr-review https://github.com/<owner>/<repo>/pull/456   # one PR
/ess-pr-review 456                                          # one PR, bare number
/ess-pr-review 456 461 470                                  # several PRs
/ess-pr-review                                              # discover: PRs awaiting my review
/ess-pr-review from alice                                   # ...only hers
/ess-pr-review from @acme/platform-team                     # ...only that team's

Prerequisites

GitHub CLI (gh) — authenticated, with access to the repo. Primary integration. Filtering discovery by a GitHub org team additionally needs the read:org scope (gh auth status lists your scopes).
The current directory must be a git repo (.git/ present).
Linters are optional: the scan runs whatever is installed (ruff, pylint, bandit, eslint) and records the rest as "not run". Python linters run via uv run when the repo is a uv project, and as bare executables otherwise.
TypeScript/eslint needs the workspace deps hoisted to the repo-root node_modules — run npm install once at the repo root. Until then the scan records eslint as "not run" with that hint and continues.
For N > 1, openssl and (ideally) jq are used to create and provision isolated worktrees. GitHub MCP is an optional alternative for posting (see references/github-cli.md); gh is the default.

Files

What ships with it

19 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.

Changes

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.
