Caveman Evidence Review

Review Caveman evidence

Act as a read-only operator. Build conclusions from current Caveman data, not from repository guesses. Never start, approve, cancel, or roll back an experiment from this skill.

Hard rules

1. Keep these buckets separate:

• measured provider-complete list-price cost;
• inferred daily headroom;
• verified ledger savings;
• evidence cost.

Never add or relabel them.

1. Do not fetch prompt, completion, tool, or artifact payloads unless the user

explicitly asks for payload review. Metadata, spans, timing, models, token counts, status, and optimizer attribution are enough for the default review.

1. Scope every read to the project selected by Caveman context. Never supply an

organization id.

1. Empty results are evidence of no current signal, not zero cost or zero risk.
2. Cite trace ids and exact time windows used. Do not claim a cause from an

aggregate alone.

Step 1 — Load context

Prefer MCP:

caveman_context {}

CLI fallback:

caveman cloud whoami
caveman cloud projects list

Stop if login or project selection is missing. Ask the user to run caveman login or select a project; never guess.

Step 2 — Establish baseline

Use caveman_report for:

• overview
• costs
• score
• workflows
• verified_savings

Then use caveman_plan for ranked daily headroom. If question is narrow, skip unrelated reports. Read shortest set that can answer it.

CLI fallback:

caveman cloud costs
caveman cloud score
caveman cloud plan --json

State report window and basis before interpreting direction.

Step 3 — Test the leading explanation with traces

Use caveman_trace_search. Choose a bounded window and closed filters: workflow, agent, model, provider, error code, runtime mode, cache status, optimization id, status class, token/cost/latency bounds, compression, or monitor verdict.

Useful groupings:

• workflow — find jobs driving cost or failures;
• model — compare model mix;
• session — isolate retry or loop behavior;
• ungrouped — identify exact traces.

Compare a suspect cohort with a control cohort or earlier bounded window. Do not infer causality from one expensive trace.

CLI fallback:

caveman cloud traces search \
  --workflow  \
  --from  \
  --to  \
  --sort total_cost_usd \
  --dir desc \
  --limit 25

Step 4 — Inspect representative traces

Call caveman_trace_get for a small number of high-signal trace ids. Inspect request and span metadata, latency, status, token counts, cache state, applied optimizers, and model route. Keep payload retrieval off.

CLI fallback:

caveman cloud traces show  --spans

Step 5 — Report

Use this shape:

If data is missing, name missing signal and stop at strongest supported statement. Never turn a catalog subtotal into an invoice or an experiment result into verified savings.
