refactor-opportunity-review

refactor-opportunity-review is an agent for coding agents from bdfinst/agentic-dev-team. It costs 28 tokens per session (1,575 once invoked), scanned A, original, MIT.

A code-review agent that looks for safe ways to simplify or restructure code after its tests pass. TDD, or test-driven development, is a practice of writing tests around a change and using them to guide implementation.

In plain words
What is it for?
Use it after a completed development slice or on demand to assess duplication, structure, coupling, complexity, nesting, and opportunities for refactoring.
Why use it?
It reviews code at the point when tests show the behaviour is working and restructuring is less risky. It distinguishes meaningful duplication from code that merely looks similar.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add agents/bdfinst/agentic-dev-team/refactor-opportunity-review
Clone the repo
git clone --depth 1 https://github.com/bdfinst/agentic-dev-team

Or install dev-team, the plugin that ships this one along with the rest of its 46 agents.

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

refactor-opportunity-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 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.

Refactor Opportunity Review

Scope: on-demand Cites:

  • design-smells
  • adversarial-review-protocol

Dispatched by name at /build's slice review checkpoint (../skills/build/SKILL.md sub-step 6) — once per slice, after its steps are green, which is the moment this agent's charter names ("assesses refactoring opportunities after tests pass") — by ../skills/test-driven-development/SKILL.md § REFACTOR 3a, and on demand via --agent refactor-opportunity-review. Never by /code-review's per-diff panel (#1976). Because those dispatches name it directly, Scope: on-demand removes it from the resolver's roster without removing it from the pipeline. A refactoring opportunity is a property of code that is already green, evaluated while the author still has the option to restructure; by the time a full review panel runs, the same ground is covered by structure-review (SRP, DRY, coupling, and — since #2093 folded complexity-review into it — nesting, cognitive load, and async-pattern judgment), which is Scope: always and overlaps this lens's findings on the same diffs. Running it in both places bought a second opinion on those axes, not a new axis.

Output JSON: per ${CLAUDE_PLUGIN_ROOT}/knowledge/review-agent-output-contract.md (Whole-file load: short, canonical schema).

Knowledge Files

Before analysis, read ${CLAUDE_PLUGIN_ROOT}/knowledge/design-smells.md#reinvented-built-in-cheat-sheet — the per-language built-in map and the "What NOT to flag" guards (version/idiom drift) for the use-the-platform findings — plus the "Reinvented built-in / helper" and "Open-coded idiom" rows in ${CLAUDE_PLUGIN_ROOT}/knowledge/design-smells.md#design-smells-pattern-mapping.

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.

refactor-opportunity-review is an agent published in the GitHub repository bdfinst/agentic-dev-team (280 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 1,575 once invoked, about $0.0001 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 2026-08-30.
