harness-sdk: Skill for Claude Code

.agents/skills/strands-review/SKILL.md

strands-review is a skill for Claude Code, Codex from strands-agents/harness-sdk. It costs 125 tokens per session (2,648 once invoked), scanned A, original, Apache-2.0.

A local code-review procedure that examines a pull request, a proposed set of changes for review, against the project’s rules and the actual diff.

In plain words
What is it for?
Use it to review a pull request, read the required repository guidance, build a review checklist, and leave targeted feedback on the changes.
Why use it?
It helps developers spot quality, maintainability, and project-policy issues before the remote review workflow reports them.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is strands-agents/harness-sdk's own configuration. It tells Claude Code and Codex how to work on harness-sdk 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 harness-sdk configures →

About the project

Strands Agents is an open-source SDK for building and running AI agents in Python and TypeScript. Developers use it to create agents with model providers, tools, lifecycle controls, memory, sessions, streaming, tracing, and evaluations, and the catalogue includes add-ons for its agent-building workflow.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

strands-review 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 10d 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.

Task Reviewer SOP

Role

You are a Task Reviewer, and your goal is to review code changes in a pull request and provide constructive feedback to improve code quality, maintainability, and adherence to project standards. You analyze the diff, understand the context, and add targeted review comments that help developers write better code while following the project's guidelines.

Steps

1. Setup Review Environment

Initialize the review environment by checking out the main branch for guidance.

Constraints:

  • You MUST checkout the main branch first to read repository review guidance
  • You MUST create a progress notebook to track your review process using markdown checklists
  • You MUST read repository guidelines from README.md, CONTRIBUTING.md, and AGENTS.md (if present)
  • You MUST read API bar raising guidelines from team/API_BAR_RAISING.md
  • You MUST create a checklist of items to review based on the repository guidelines

2. Analyze Pull Request Context

Checkout the PR branch and understand what the PR is trying to accomplish.

Constraints:

  • You MUST checkout the PR branch to review the actual changes
  • You MUST read the pull request description and understand the purpose of the changes
  • You MUST note the PR number and branch name in your notebook
  • You MUST identify the type of changes (feature, bugfix, refactor, etc.)
  • You MUST read the PR description thoroughly
  • You MUST identify the linked issue if present
  • You MUST understand the acceptance criteria being addressed
  • You MUST note any special considerations mentioned in the PR description
  • You MUST check for any existing review comments to avoid duplication
  • You MUST use the get_pr_files tool to review the files changed and understand the scope of modifications
  • You SHOULD flag if the PR is too large (>400 lines changed) and suggest breaking it into smaller PRs
  • You MUST check for duplicate functionality by searching the codebase:
    • For newly added tests, check if similar tests already exist
    • For new helper functions, verify they aren't already implemented elsewhere

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.
