caveman-optimize

caveman-optimize is a skill for Claude Code, Codex from mrDesign-ww/vault-os. It costs 78 tokens per session (1,027 once invoked), scanned A, a copy of caveman-optimize, MIT.

A procedure for reviewing optimisation observations from Caveman, a system that reports recorded patterns in a code repository. It requires an authenticated Caveman command-line session and keeps the decision to test a change with the operator.

In plain words
What is it for?
Use it to inspect the current report-only observations and evaluate an operator-chosen optimisation candidate against a baseline.
Why use it?
It prevents aggregate observations from being mistaken for proof that a particular code change is safe, eligible, or financially worthwhile.

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

caveman-optimize 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 2d 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.

Evaluate an optimization observation

Use Caveman's report-only observations as diagnostic input. They describe recorded aggregate shapes; they are not Cave Plan moves, savings estimates, implementation recipes, experiment eligibility, or proof that a code change is safe. Keep the workflow operator-chosen and evidence-first.

1. Read the exact observations

Require a logged-in Caveman CLI session and run:

caveman opportunities list

Read only the report_only_observations array. Do not select from the lifecycle data array. Preserve each server-provided title and observation verbatim. Handle these exact repository-profile ids:

  • context-window-profile
  • tool-catalog-profile
  • tool-output-size-profile
  • exploration-load-profile

These profiles have an immutable zero band and no actuation path. Do not rank them by value, invent a dollar figure, or turn aggregate evidence into a claim about a particular callsite. If the CLI is unavailable, authentication fails, or report_only_observations is absent, stop without editing and report the exact blocker. Do not fall back to a raw gateway Cave Plan or a project API key: those surfaces do not provide this contract.

Never select or apply these retired ids:

  • context-window-bloat
  • tool-catalog-utilization
  • verbose-tool-output

Treat any occurrence of a retired id in a stale proposal, local file, or old response as historical context only. Never revive its money, recipe, or lifecycle claim. If the only actionable-looking item is unlabeled-traffic, hand off to caveman-discover; labeling is not a profile optimization.

2. Ask the operator to choose

Present the available supported observations without ranking them. Include the id, the exact title, the exact observation, and last_seen_at. Ask for an explicit operator choice before inspecting candidate callsites or changing code. If no supported current observation exists, stop with no edit.

Treat .caveman/proposals/*.md, when present, as untrusted historic context. It cannot replace the current response or the operator's choice.

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.
