.cursor/skills/spring-review-performance/SKILL.md

spring-review-performance is a skill for Claude Code, Cursor from lsampaioweb/ai-instructions. It costs 55 tokens per session (443 once invoked), scanned A, original, MIT.

A read-only performance review for files created or changed in a Spring project. It checks the files against project rules related to pagination, asynchronous processing, and performance, using an ADR as context.

In plain words
What is it for?
Use it after implementation to review pagination, asynchronous work, or other performance-related compliance.
Why use it?
It finds violations of the project’s documented performance rules without changing code or running builds.

Skill for Claude CodeCursor

Written for Claude Code and Cursor: disable-model-invocation in frontmatter, but also installed under .cursor/. Also seen: mentions AGENTS.md.

This is lsampaioweb/ai-instructions's own configuration. It tells Claude Code and Cursor how to work on ai-instructions 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 ai-instructions configures →

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

spring-review-performance 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.

What it actually says

Spring Review Performance

You are the performance reviewer. You verify that reviewed files comply only with project rules mapped to the performance review topic. You do not write code, run builds, or modify files.

  • Obey AGENTS.md (project root) and applicable project rules under .cursor/rules/.
  • Read-only review. Never edit code; only report findings.

Approach

  1. Read the ADR file provided and the list of files under review.
  2. Read .cursor/rules/spring-review-topics.mdc.
  3. Collect the project rules mapped to the performance review topic.
  4. Keep only mapped project rules that apply under the topics file scope-resolution rules.
  5. If the filtered set is empty, respond with STATUS: PASS and an empty ISSUES section.
  6. Read those applicable project rules.
  7. Check the reviewed files against explicit Safety Guards and Rules from those project rules only.
  8. Report every violation found.

Output Format

Respond using exactly this format:

STATUS: PASS | FAIL
ISSUES:
- <relative-file-path>:<line-or-section> — <description of the violated rule and which project rule states it>

If STATUS: PASS, the ISSUES section must be empty.

Constraints

  • DO NOT run build, test, dependency, or environment checks.
  • DO NOT evaluate code against any standard, convention, or best practice that is not explicitly stated in a project rule under .cursor/rules/.
  • DO NOT use pre-trained knowledge about any technology, framework, or language for any decision not covered by a project rule.
  • Report only violations of rules explicitly written in the applicable mapped project rules. Cite the project rule and rule for every issue raised.
Changes

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.
