Performance Profile

STOP - Read before ANY tool call

1. Read E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/.grok/rules/guardrails.md
2. Read E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/skills/_shared/sdd-artifacts/SESSION.md; load session-state for $Cwd
3. If the relevant gate is not approved: STOP - ask user (pt-BR) - do NOT Write/Shell
4. SDD/develop skills: after ONE step/task, STOP session - handoff only
5. This skill body is English; user-facing prompts may be (pt-BR)

Step -1 - Gate check (report in chat before continuing)

Gate check:
[ ] guardrails.mdc read
[ ] SESSION.md read; session-state loaded
[ ] PIPELINE.md read (SDD skills only)
[ ] User confirmed current action (sim)
-> If any unchecked: STOP

Skill: performance-profile

Trigger

Invoke when the user requests: /performance-profile, optimize performance, /performance-profile, or asks to fix query bottlenecks.

Arguments (optional):

Outcome

Documented performance improvements verified by local benchmarking:

1. Identified bottlenecks (SQL/LINQ analysis, loop allocations).
2. Optimization proposal (e.g., eager loading, projection, indexes, caching, memory span allocations).
3. Micro-benchmark results comparing execution speed and memory allocations (before vs. after).

Lazy-load

Process

Step -1b - Caveman Mode (Full cap)

1. Read E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/sdd/preferences.json (create { "caveman_mode": false, "caveman_level": "full" } if missing).
2. If caveman_mode is false: continue without compression.
3. If true: load E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/skills/_shared/caveman/CAVEMAN.md; apply Full participation cap + prefs caveman_level (Lite skills never escalate); show once: [Caveman] Modo ativo (respostas compactas, level={effective}). Digite caveman off para desativar.
4. Honor caveman on|off|status|lite|full|ultra (and stop caveman / normal mode) during the session.
5. Auto-Clarity + never-compress gates/drafts/paths per CAVEMAN.md.

-1. Re-check guardrails and session

Confirm guardrails.mdc and SESSION.md are loaded. If missing, ask user (pt-BR):

Antes do profiling, confirme:
- guardrails.mdc lido
- SESSION.md carregado

0. Target Identification

• Locate the target method, database routine, or loop structure.
• Confirm what metrics are critical: Execution Time (ms) or Memory Allocation (MB/GC cycles).

1. Static Performance Audit & Workflow Decision

• Analyze the target code for common anti-patterns:
  • Database: N+1 queries (no eager loading), lack of projection (select new), missing query limits (Take/limit), unindexed search fields.
  • Memory: Excessive allocations inside loops, duplicate string concatenations, boxing/unboxing.
• Present the diagnostic report summarizing the bottlenecks.
• Stop and ask the user to choose the workflow execution path for applying and benchmarking these optimizations:
  • Option A - Direct Developer Skill (/developer): For straightforward local optimization and benchmark setup.
  • Option B - Classic SDD (/sdd-spec -> sdd-plan -> sdd-develop): For complex structural refactorings or query tuning requiring formal specifications (PRD) and a detailed plan (PLAN) in Portuguese.
  • Option D - Plain Chat Plan: Establish a simple task list directly in the chat, executing steps one by one without extra file creations.
• Wait for explicit user choice before writing code or initializing another workflow.

2. Configure Benchmark

• Propose the setup for a benchmark suite:
  • C#: Create a BenchmarkDotNet class under the test project.
  • Python: Write a test script utilizing timeit or cProfile.
  • TS/JS: Write a benchmark script utilizing Node's perf_hooks or benchmark.js.
• Wait for confirmation, then write the benchmark script/class.

3. Collect Baseline (Before)

• Instruct the user/agent to run the benchmark script and capture the execution outputs:
  • Capture Mean Time, Standard Deviation, and Allocated Bytes.
• Document the baseline metrics.

4. Implement & Verify Optimization

• Write the optimized implementation in a separate branch or method variant (e.g. CalculateOptimized).
• Run the benchmark again to compare:
  • Verify that optimization achieves measurable improvements (e.g. 20% speedup or lower GC allocation) without regression.
• Present a comparison table:

5. Apply Final Changes

• Replace the old code with the validated optimized version.
• Run compiler checks and regular test suites to ensure behavior remains identical.

6. Handoff

• Offer committing the optimizations:

/commit

Must not

• Perform optimizations without a benchmark validation.
• Introduce breaking changes or bypass domain validation rules to improve speed.
