pre-landing-review

pre-landing-review is a skill for Claude Code from Mathews-Tom/armory. It costs 68 tokens per session (996 once invoked), scanned A, original, MIT.

A checklist-based safety audit for code changes before they are merged. It classifies findings as blocking or non-blocking using two review passes.

In plain words
What is it for?
Use it to check a branch, pull request, or selected files before landing the change and to identify issues that should stop the merge.
Why use it?
It provides a repeatable merge gate focused on release safety, rather than a broad review of every aspect of code quality.

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

pre-landing-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 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.

Pre-Landing Review

Gate-oriented safety audit for code changes before landing. Uses a structured checklist with two-pass severity triage and blocking/non-blocking classification.

Distinct from pr-review: pr-review is a multi-dimension code quality review. This skill is a gate-oriented safety audit — it uses an external checklist with two-pass severity triage and a blocking/non-blocking classification.

Native alternative: Claude Code's /ultrareview runs a dedicated native review session optimized for bug-finding (Anthropic ships three free per month on Pro/Max plans at Opus 4.7's launch). Use this skill for checklist-driven, gate-oriented blocking classification with a documented triage protocol; use /ultrareview for lightweight bug-hunting on a single change.

Workflow

1. Determine Diff

Identify the changes to review:

  • If on a feature branch: diff against the default branch (git symbolic-ref refs/remotes/origin/HEAD)
  • If given a PR number: fetch that PR's diff
  • If given specific files: review those files

2. Load Checklist

Read references/checklist.md. This is mandatory — if the checklist is unreadable, STOP and report the error.

3. Pass 1 — CRITICAL (blocking)

Review the diff against critical safety categories. These are potential ship-blockers.

SQL & Data Safety
  • Raw SQL without parameterization
  • Schema changes without migration safety (lock timeout, reversibility)
  • Bulk updates/deletes without WHERE clause verification
  • Direct column updates bypassing model validations/callbacks
Race Conditions & Concurrency
  • Read-then-write without locking
  • Unique constraint reliance without database-level enforcement
  • Shared mutable state without synchronization
  • Queue/background job idempotency
Trust Boundaries
  • LLM/AI output used in SQL, shell commands, or rendered HTML without sanitization
  • User input reaching privileged operations without validation
  • External API responses used without schema validation
  • Deserialization of untrusted data

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.
