cop-review

A pre-merge code review command that compares your current branch with a target branch, such as main or develop. A branch is a separate line of code changes, and merging combines it with another branch.

In plain words
What is it for?
Use it to review a branch, run TypeScript or .NET build and formatting checks, choose junior or senior explanations, and limit the review to a specified scope.
Why use it?
It finds issues before a pull request is merged and chooses checks suited to Angular/TypeScript or .NET projects.

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

cop-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 yesterday.

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

/cop-review — Pre-Merge Review

Review the current branch against a target branch before merging.

Stack-aware delegation

Detect the project stack in cwd from these signals, then delegate via Agent tool to the matching subagent:

Signal Stack Subagent to delegate to Tooling
angular.json present Angular + TypeScript angular-cop npx tsc --noEmit + npm run lint
*.csproj / *.sln / *.slnx / global.json present .NET dotnet-cop dotnet build --nologo -clp:ErrorsOnly + dotnet format --verify-no-changes

If BOTH are present (rare monorepo), check which language the diff files are in (.ts/.html → angular-cop; .cs/.csproj → dotnet-cop). Delegate to both subagents when the diff contains both language groups. If ambiguous, default to angular-cop and note the ambiguity in your findings.

Usage

/cop-review <target-branch> [--level=junior|senior] [--scope=...] [--no-tools]
  • <target-branch> (required) — the branch the PR will merge into (e.g. main, develop, release/2026.05).
  • --level=junior — verbose teaching mode with rationale + doc links for every finding.
  • --level=senior (default) — terse one-liners.
  • --scope=... — limit to a subset of checklists. Comma list. Defaults to all.
  • --no-tools — skip tooling checks and produce static review only (faster).

What you do

  1. Parse the arguments:
    • Extract the target branch from the first positional argument.
    • If target is missing, print usage and stop.
  2. Detect the stack from the signals above.
  3. Call Agent with subagent_type: "angular-cop" or subagent_type: "dotnet-cop" (or both for monorepos with mixed content), passing the full command arguments. The subagent owns the rest: resolve the review window, load the applicable skill(s), run tooling, and render the report.
  4. Synthesis: Subagents report findings only. After they complete, synthesize and return the unified review to the user.

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.

cop-review is a command published in the GitHub repository fmflurry/settings-opencode (172 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 603 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
