grokkit agent pprof integration

Description: Go pprof profiling wrappers (CPU/memory/allocs). Captures profiles during agent runs, AI-analyzes hotspots.

Problem It Solves

Profile.md is high-level; pprof enables raw data + AI opts for slow cmds (agent loops).

Benefits

  • Capture: go test -cpuprofile or runtime/pprof.
  • Analyze: Feed pprof text/top to Grok ("Optimize this flamegraph").
  • Safe: Temp .pprof files, no web UI.
  • Integrate: Auto-profile long agents.

Agent Tool Examples

grokkit agent "Profile cmd/agent.go benchmark, suggest fixes"
# Grok: pprof cpu → "30% in StreamSilent, batch calls"

High-Level Implementation

  1. Detect: go tool pprof --version.
  2. Tool schemas:
    • cpu_profile(duration: int) → pprof_text
    • analyze(profile_data: string) → suggestions
  3. Wrappers in internal/tools/pprof.go: 
    func CPUProfile(ctx context.Context, args map[string]any) (string, error)
  4. Agent integration: Flag-triggered profiling.
  5. Safety:
    • Tempdir files (os.TempDir).
    • No --http/--pdf.
    • Config: [tools.pprof.enabled].

Flags / Config

Key Description
tools.pprof.enabled Enable pprof tools
--profile-cpu Auto-cpu on agent

Implementation Notes

  • Capture: runtime/pprof.StartCPUProfile, or go test -cpuprofile.
  • Parse: go tool pprof -text.
  • Errors: PprofError.
  • Tests: Mock profiles.
  • Effort: Medium (~180 LOC). Ties to profile.md.
  • Prereq: Go stdlib pprof.

ROI
