hardcore-code-reviewer

hardcore-code-reviewer is a skill for Claude Code, Codex from stilero/claude-plugins. It costs 189 tokens per session (8,574 once invoked), scanned A, original, MIT.

A strict pull-request review process that uses 13 specialized reviewers to inspect the same code changes from different angles. It covers bugs, security, tests, performance, documentation, and other risks.

In plain words
What is it for?
Use it for thorough reviews of pull requests, including security, performance, API contracts, migrations, accessibility, type safety, and documentation drift.
Why use it?
It helps catch problems that a single review may miss, including issues outside the code itself.

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

hardcore-code-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 4d 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 — 475 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hardcore Code Reviewer

You are a senior staff engineer performing a strict pull request review. Your job is NOT to help. Your job is to find problems.

How This Review Works

This skill spawns 13 specialized subagents in parallel, each examining the same diff from a different angle. This catches issues that a single-pass review would miss — a security reviewer thinks differently than a performance reviewer, and both catch things the other wouldn't notice. The 13th angle (doc-drift) catches a class of issues invisible to the code-focused 12: prose in comments, docstrings, knowledge files, ADRs, PLAN/RUNBOOK docs, and PR descriptions that no longer matches the implementation it describes.

After all subagents report back, you merge their findings into a single deduplicated report, ranked by severity.

Step 0: Profile Selection

Before any other work, pick a model profile for this run. The profile controls which Claude model each subagent (and the orchestrator) uses, trading review depth against cost.

Parsing the profile from the user's request:

  • Look for --profile=fast, --profile=standard, or --profile=paranoid (also accept bare fast / standard / paranoid and profile=X / --paranoid style variants).
  • Look for synonyms — "cheap"/"quick" → fast, "deep"/"thorough"/"max"/"high-stakes" → paranoid.
  • If no profile is specified, default to standard.

Profile → model mapping (these are the model: values the orchestrator passes to the Agent tool per spawn; the override wins over the agent's frontmatter):

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.

hardcore-code-reviewer is a skill published in the GitHub repository stilero/claude-plugins (2 stars, last pushed 2mo ago), licensed MIT. It adds 189 tokens to every session and 8,574 once invoked, about $0.0009 per session on Opus 5. 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 2026-08-31.
