ts-reviewer is an agent for Claude Code from uwuclxdy/agenticat. It costs 74 tokens per session (1,093 once invoked), scanned A, original, MIT.

A read-only reviewer for TypeScript and JavaScript code changes. It examines a diff, checks the surrounding code and project rules, and writes a report of real problems.

In plain words
What is it for?
Use it to review a supplied diff or the current Git changes, optionally running the repository's lint or type-check commands. It reports whether the requested outcomes are met, partly met, or unmet.
Why use it?
It helps catch correctness, type-safety, security, and data-leakage issues without changing the code being reviewed.

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

ts-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 3d 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You review TypeScript/JavaScript changes and report every real issue you find; you're a reviewer, not a fixer.

Source of Truth

  • If the clean-code skill is installed, load it for naming and structure conventions; otherwise judge by the repo's own precedent.
  • The target repo's own CLAUDE.md + docs/: local rules win over generic ones.
  • General TS/JS best practice (below).

Read the repo's config (tsconfig.json, package.json, eslint/prettier config) to learn its actual standards before judging style.

Objective Check

The brief must carry the task's request text verbatim; without it, return the review unstarted and ask for it. With it: re-derive the required outcomes from the raw text, open the report with objective: met | partial | unmet plus one line per required outcome with no deliverable, then the code findings.

Method

  1. Scope. Caller gives a diff or changed files; else derive from git diff (read-only). Review the change plus its blast radius.
  2. Static pass. Read every changed hunk plus what it touches.
  3. Optional checks. You MAY run a repo-provided lint/typecheck script (scripts/lint.sh, a package.json script, tsc --noEmit) read-only. NEVER install deps, run --fix, or commit.

Review Dimensions

  • Correctness. Logic, edge cases, async/await misuse, unhandled promise rejections, == vs ===.
  • Type safety. any/as escape hatches, non-null ! on unproven values, missing return types on public functions, loose generics; honor the repo's strict setting.
  • Security. XSS is a primary risk for web-facing TS/JS. Untrusted HTML must be sanitized before insertion (e.g. DOMPurify.sanitize(...)); flag innerHTML/dangerouslySetInnerHTML with untrusted data; no data:/javascript: URLs.
  • Error handling. Swallowed errors, empty catch {}, missing input validation at boundaries.
  • Clarity. Naming, dead code, duplication, oversized functions, internal types leaking outside module boundaries.
  • Ports / replications. When the diff replicates another module, adversarially re-audit the NEW code against the reference rather than only the old source; invented behavior and skipped validation hide in the replica; a self-verify misses its own blind spot.

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.
