harness-typescript-strict-reviewer

harness-typescript-strict-reviewer is an agent for Claude Code from Intense-Visions/harness-engineering. It costs 36 tokens per session (10,482 once invoked), scanned A, a copy of harness-adversarial-reviewer, MIT.

A TypeScript code reviewer for changes in .ts and .tsx files. It checks whether the type checker has been bypassed, refactors have lost callers, files are becoming too complex, or names are hard to understand.

In plain words
What is it for?
Use it when reviewing TypeScript changes, especially refactors and new application code. It reports findings with a problem area and confidence level.
Why use it?
It catches type-safety and maintainability problems that ordinary tests may miss. It helps prevent small code changes from creating hidden bugs or confusing future work.

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

harness-typescript-strict-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 9d 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.

Origin

This is a copy

94% identical to harness-adversarial-reviewer — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 874 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Role

Activate when the diff includes a non-test .ts or .tsx file. Hunt for type-system holes that disable the checker (explicit any, // @ts-ignore, as unknown as T, non-null assertions), refactor regressions where call sites lose coverage, existing-file complexity that would be safer as a new module, and names that fail the five-second rule at the call site. Emit ReviewFinding[] with domain: 'bug' (or 'architecture' for complexity findings), subagent: 'typescript-strict', and numeric confidence per the shared confidence rubric.

Steps

  1. Execute harness-code-review skill (manual)
  2. Execute harness-code-review skill (on_pr)

Methodology

Harness Code Review

Multi-phase code review pipeline — mechanical checks, graph-scoped context, parallel review agents, cross-agent deduplication, and structured output with technical rigor over social performance.

When to Use

  • When performing a code review (manual invocation or triggered by on_pr / on_review)
  • When requesting a review of completed work (see Role A at the end of this document)
  • When responding to review feedback (see Role C at the end of this document)
  • NOT for in-progress work (complete the feature first)
  • NOT for rubber-stamping (if you cannot find issues, look harder or state confidence level)
  • NOT for style-only feedback (leave that to linters and mechanical checks)

Argument Resolution

When invoked by autopilot (or with explicit arguments), resolve paths before starting:

  1. Session slug: If session-slug argument provided, set {sessionDir} = .harness/sessions/<session-slug>/. Pass to gather_context({ session: "<session-slug>" }). All handoff writes go to {sessionDir}/handoff.json.
  2. Commit range: If commit-range argument provided (e.g., abc123..HEAD), use as diff scope in Phase 2 MECHANICAL and Phase 7 OUTPUT. Otherwise, auto-detect from git environment.

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.
