review-handoff

A command that creates a self-contained hand-off brief for another agent or reviewer.

In plain words
What is it for?
Handing off a branch, commit, pull request, local changes, staged changes, or a specific file.
Why use it?
It lets a fresh session understand the exact project state without access to the current conversation.

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.

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.

Security

Grade A, and why

review-handoff 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 3d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Handoff - Brief for an External Reviewer

Produce ONE message the user copies into another agent. That agent has NO context: not this conversation, not the task, not even which repo. The brief must be complete on its own.

  • The brief is the deliverable - do not review anything yourself, do not edit any file
  • Target selectors mirror /lets:review, so the same flag reviews here or hands off there; works in any git repo, with or without LETS

IMPORTANT: If the spec below invokes any deferred tool (e.g. AskUserQuestion), you MUST load and call it as specified. Never skip the call, never substitute a default answer of your own — the tool invocation is part of the contract. This is critical.

Usage

/lets:review-handoff                      # infer the target from context; asks only if genuinely ambiguous
/lets:review-handoff <PR-url-or-number>   # GitHub or Bitbucket PR
/lets:review-handoff --pr <id-or-url>     # alias of the bare form above
/lets:review-handoff --local              # uncommitted changes
/lets:review-handoff --staged             # staged changes only
/lets:review-handoff --last-commit        # last commit
/lets:review-handoff --branch             # full branch vs the merge branch (three-dot, like a PR)
/lets:review-handoff --plan               # newest plan in .lets/plans/
/lets:review-handoff --plan <path>        # a specific plan file
/lets:review-handoff --file <path>        # one file
/lets:review-handoff --commits <N>        # handoff-only: the last N commits (a fix round)
/lets:review-handoff --range <a>..<b>     # handoff-only: an explicit range
/lets:review-handoff --spec <path>        # what the reviewer judges against (or a bare task id)
/lets:review-handoff --spec none          # deliberately no spec - no spec line, no caveat

Selectors match /lets:review, with two deliberate differences: --commits / --range are handoff-only (review has no target for "the commits that answer a review round"), and --pr is kept as an alias because it is the spelling this tool shipped with. Review's output modifiers --json and --workflow are not implemented here.

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.
