blackfish: Command for Claude Code

.claude/commands/pr-checklist.md

pr-checklist is a command for Claude Code from princeton-ddss/blackfish. It costs 0 tokens per session (246 once invoked), scanned A, original, MIT.

A checklist for reviewing code before creating a pull request, which is a proposed change submitted for team review. It covers code quality, tests, linting, documentation, commits, and branch status.

In plain words
What is it for?
Use it before opening a pull request to verify tests, linting, coverage updates, documentation, commit quality, and readiness of the branch.
Why use it?
It reduces the chance of submitting changes with failing tests, missing documentation, unclear commits, or an outdated branch. It also records project-specific commands for Python and frontend checks.

Command for Claude Code

Written for Claude Code: installed under .claude/.

This is princeton-ddss/blackfish's own configuration. It tells Claude Code how to work on blackfish itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything blackfish configures →

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

pr-checklist 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 5d 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.

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.
