What is review-this-branch?

A skill for reviewing the current Git branch or a GitHub pull request with an independent, adversarial agent review. It also checks whether tests were tampered with and reports file-and-line findings.

Use it to check whether a branch or pull request is safe to merge and to get a pass-or-fail checklist.

It provides a second review rather than relying on the author or a summary of the changes. It runs without a server or database and does not claim success when required tools or credentials are missing.

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.

Any agent

npx skills add no-human-ai/no_human --skill review-this-branch

Clone the repo

git clone --depth 1 https://github.com/no-human-ai/no_human

Made for: Claude Code.

Or install no-human, the plugin that ships this one along with the rest of its 3 skills, 1 MCP server.

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	$0.00053	$0.01404
Opus 5.5	$0.00021	$0.00562
Sonnet 5.5	$0.00011	$0.00281

Security

Grade A, and why

review-this-branch 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 1mo 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review this branch

Run nh gate to get a fresh-session, adversarial code review and a test-tampering check over a diff, right now, with nothing installed or running beyond the nh CLI itself.

When to use

Someone asks "review this branch" / "check this PR" / "is this safe to merge" and wants a real second-model review with file:line citations, not a summary you write yourself.
There is no no_human server running and no ~/.no_human database set up. Unlike file-a-task, this skill needs neither. It runs once and exits.

Prerequisite: your own Claude credential

nh gate uses your own Claude credential, the same one every other nh command uses, never one belonging to no_human itself. If none is on file, create it with:

claude setup-token

nh gate also needs the nh CLI on PATH and a claude CLI it can find: the one bundled inside the installed SDK package is used first, so a separate install on PATH is not required. If either precondition is missing, the command refuses and names exactly what is missing. It never prints a pass when it could not actually run.

Running it

Two invocations, both read-only:

nh gate                        # current branch vs. its merge base with origin's default branch
nh gate --pr <github-pr-url>   # a GitHub pull request's head vs. its merge base

Optional flags: --repo <path> to point at a checkout other than the current directory, --base <ref> to override the comparison base.

The comparison actually used, for example working tree branch ... against merge base with origin/<default> or pull request owner/repo#N head ... against merge base with origin/<default>, is always printed at the top of the output. If the working tree has uncommitted changes, the output says so explicitly and those files are not reviewed; commit them first if they should be.

Reading the result: the exit-code contract

Exit code	Meaning
`0`	Gate passed: reviewer found no blocking findings and the tamper guard found no test-weakening.
`1`	Gate failed: a blocking review finding or a tamper-guard finding (deleted/weakened tests).
`2`	Gate refused to run: no review verdict was reached at all. A named precondition failed: no credential, no upstream, not a git repo, PR fetch failed, the diff is over the single-turn review cap, or the reviewer timed out / hit a transport error.

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.
