deadeye-review

deadeye-review is a skill for Claude Code from deepaksinghcs14/deadeye-cc. It costs 33 tokens per session (4,824 once invoked), scanned C, original, MIT.

A review of code for unnecessary complexity, usually limited to the current Git diff unless whole-repository mode is requested. A Git diff is the set of changes between two versions of a project.

In plain words
What is it for?
It is for finding over-engineered changes, checking whether code is actually used, and ranking possible deletions or simpler replacements.
Why use it?
It helps identify code that can be removed or simplified without turning the review into a general correctness or security audit.

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 C, and why

deadeye-review scanned grade C with 3 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deadeye Review

Review code through four lenses — over-engineering, correctness, performance, security — the same rubric /deadeye-pr runs on a whole pull request, scoped instead to your working diff or the whole repo. This is the local, pre-PR self-review: catch what would otherwise wait for a PR (or a bot) to find. For a real GitHub PR, use /deadeye-pr. For a deeper, dependency-audit-backed security-only pass, use /deadeye-guard.

Two scopes:

  • default — the current working diff.
  • --repo (or "audit the whole repo") — the entire repository, ranked worst-first across all four lenses. See "Whole-repo mode" below.

Scope (default: the working diff)

Get the diff with git diff (or git diff --staged if the user says staged, or git diff <ref> for a named base). Read the changed hunks plus enough surrounding context to judge a trust boundary or a caller contract — "is this input validated" and "does this break a caller" both need the code around the hunk, not just the + lines.

  • Empty diff (nothing changed or staged): say so plainly and stop — do not substitute a different scope.
  • Not a git repo: ask the user which files to review.

Before tagging yagni:/delete:, or claiming an authz/nil/sanitizer check is MISSING, grep for implementers/callers/guards OUTSIDE the diff — an "interface with one impl" whose second impl lives in a test file, or a guard that lives one call down, is a false positive. Report only what you confirmed.

Verify before reporting

Before claiming a check is MISSING — a sanitizer, an authz guard, a nil-check — grep OUTSIDE the diff AND follow the value into the callee: a base class, a caller that guards, or the deeper function it's handed to — the real guard often lives one call down. An authz/bypass claim needs a concrete input that reaches the sink, or drop it; one wrong finding erodes trust in all of them.

deadeye-review is a skill published in the GitHub repository deepaksinghcs14/deadeye-cc (5 stars, last pushed yesterday), licensed MIT. It adds 33 tokens to every session and 4,824 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 3 findings (downloads and executes remote code, cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
