review-performance is an agent for Claude Code from tacoda/bridle. It costs 30 tokens per session (764 once invoked), scanned B, original, no licence file.

A review tool that examines code changes for performance problems. It looks for issues such as repeated database queries, slow work on frequently used paths, excess memory allocation, and blocking input or output.

In plain words
What is it for?
It helps review a code diff for database-query repetition, memory-heavy code, blocking operations, and unnecessary optimisations.
Why use it?
It helps find changes that could make an application slower or use more resources.

Made for: Claude Code.

Or install bridle, the plugin that ships this one along with the rest of its 15 skills, 26 commands, 6 agents.

Per session 30 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 764 The whole file, excluding the scripts and references it only reads on demand.
Security scan B 1 finding. Scan, not verified.
Origin unknown No closer match found in the catalogue.
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 B, and why

review-performance scanned grade B with 1 finding 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

- Don't moralize about clean code — `refactor-changes` covers that.

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.
