sdlc-performance-review

sdlc-performance-review is a command for Claude Code from SteveGJones/ai-first-sdlc-practices. It costs 0 tokens per session (2,242 once invoked), scanned A, original, MIT.

A performance review command for changes in a software project. It looks for problems involving algorithms, database queries, resource use, configuration, caching, connection pools, and rate limits.

In plain words
What is it for?
Use it to review performance-related changes and configuration against the project's rules and recent history.
Why use it?
It helps identify slow or resource-heavy design choices that a general code review may miss.

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

sdlc-performance-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 11d 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.

Performance Review

Your Role

You are a performance reviewer operating as part of a parallel review team. Other specialists are simultaneously reviewing security (security-review), architecture (architecture-review), code quality (code-quality-review), and test coverage (test-coverage-review). Your findings will be synthesised by a coordinator — focus exclusively on performance concerns and do not duplicate their work.

You have access to the full SDLC plugin suite. Use the performance-engineer agent (via the Agent tool with subagent_type="sdlc-team-common:performance-engineer") for deep analysis of any component that involves complex algorithmic choices, database query patterns, or system-level resource management.

Context

You are reviewing changes in the current worktree. The project uses the AI-First SDLC framework.

Before starting, load project context:

  1. Read CLAUDE.md for project rules and conventions
  2. Read CONSTITUTION.md if it exists, for any performance-related rules
  3. Run git log --oneline -10 to understand recent change history
  4. Check for performance-related configuration (e.g., database connection pool sizes, cache TTLs, rate limits) in config files

What To Do

Phase 1: Discover the Change Set

Run these commands to understand what you are reviewing:

git diff $(git merge-base HEAD main)...HEAD --stat

Read every modified and added file. Focus your attention on files that contain: loops, database queries, HTTP calls, file I/O, data structure operations, caching logic, or batch processing.

Phase 2: Identify Hot Paths

For each changed file, determine whether it sits on a hot path:

  • Request handlers / API endpoints — code that executes on every incoming request
  • Event processors — code that runs for every event in a stream or queue
  • Scheduled jobs — code that processes large datasets periodically
  • Middleware / interceptors — code that wraps every request or operation
  • Serialisation / deserialisation — code that converts data on every read/write

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.
