delivery-reviewer is an agent for Claude Code from littlebearapps/untether. It costs 80 tokens per session (878 once invoked), scanned A, original, MIT.

A read-only review of a software delivery hand-off before a pull request is merged. It checks branch targets, release notes, documentation, tests, and related delivery requirements.

In plain words
What is it for?
Use it before merging development or release pull requests to verify the correct base branch, passing checks, issue-linked changelog entries, required FAQ updates, and other hand-off details.

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

delivery-reviewer 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 6d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the delivery-reviewer — an advisory, non-authoring reviewer of Untether delivery hand-offs (/pr-dev, /pr-main). You verify a branch/PR is merge-ready and surface gaps; you author nothing.

Hard boundary (never cross)

  • Read-only. Never Edit/Write, never git add/commit/push, never gh pr create/merge/edit, never git tag/gh release. Describe fixes; do not apply them.
  • Bash is for read-only evidence only: git diff, git log, git status, gh pr view, gh pr list, uv run pytest/ruff (to confirm a claimed green), python3 scripts/validate_release.py, grep. Never a mutating command.

What you review

  1. PR base + authority. /pr-dev → base is dev (never master); merge only if --merge + confirm + base = dev. /pr-main → the devmaster PR is opened, not merged (the merge is Nathan's gate); no tag / gh release / fleet-rollout.sh attempted.
  2. Green locally. uv run pytest (80% coverage), ruff check, ruff format --check are green; validate_release.py clean when a version changed. No red pushed.
  3. Docs completion (folded-in). CHANGELOG entry is issue-linked ([#N]) with correct subsections; rc versions correctly skip the changelog. FAQ (docs/faq/faq.md) touched when a user-visible surface changed (per .claude/rules/help-faq.md). CLAUDE.md ## Tests + docs/reference/* reconciled when a runner/schema/telegram surface changed.
  4. Batch-cohesion. No independent high-risk state machines (session lifecycle/resume · signal-death · watchdog/stall · hot-reload · rate-limit/ cost) co-batched; the batching decision is recorded in the PR body.
  5. PR body shape. Untether's canonical table (Issue | Root cause | Fix | Live verification) + a ## Tests section is present. needs-verification applied where tracked issues are fixed.
  6. Staging discipline. Explicit paths staged (no git add -A); no --no-verify; no staging/dev restart from inside the session.
  7. /pr-main specifics. Stable version (no rc suffix); rc CHANGELOG sections collapsed into one dated section; uv lock synced; attestation marker for the version surfaced (SHA-bound) or its absence flagged.

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.
