Reports & Metrics

Gump tracks structured metrics for every run. Use gump report to see them.

Basic report

Detailed step view

gump report --detail build/task-1/converge

Step: build/task-1/converge
─────────────────────────────────────────────────
Agent:     claude-sonnet → claude-opus (escalated at attempt 4)
Type:      code

​
What Gump measures

​
High confidence (100%)

Deterministic and exact: git diff, gate exit codes, wall-clock duration, retries, guard triggers.

​
Medium confidence (~80%)

Tracked live from the agent stream: tokens (in, out, cache), cost estimates, timestamps, context window usage.

​
Reconstructed (~50%)

Inferred from heuristics: turn count, turn classification (coding, execution, exploration, planning), shell classification for Codex.

​
Key metrics

Cost — Per step, per task, per run. Based on published provider pricing. TTFD (Time To First Diff) — Time between agent launch and first file modification. Long TTFD = agent exploring before writing. Useful for prompt optimization. Stall detection — tool_error_count, correction_loops, fatal_loops, repeated_action_loops. These appear in gump report --detail. Context window usage — How much of the agent’s context window was consumed per step.

​
Analytics model

Event → Turn → Step → Run
Each event carries a timestamp and semantic labels. Turns are classified by dominant activity. Steps aggregate turns. Runs aggregate steps.
