Accessibility tree
Browser-provided semantic representation of page roles, names, states, and relationships. Caveman browser bridge uses it as a compact alternative to full page markup when visual pixels are unnecessary.Agent profile
Declarative description of how CLI launches and configures a supported agent, including wire protocol and endpoint injection plus any hooks, skills, or plugins.Basis
Label explaining how a number was produced, such as inferred, provider-reported, benchmark counterfactual, or verified.Byte-safe
Model-visible bytes remain unchanged, as in record mode. Compression, TOON, pixel, and rewriting are not byte-safe.Cave Plan
Connected product report ranking possible efficiency improvements. A plan item is a proposal and does not establish verified savings.Cave Score
Connected product score summarizing measured efficiency signals under its published contract. It is distinct from local Engine token reduction.Caveman Cloud
Optional connected account, evidence, and governance service. Local compression does not require it.CCR
Caveman Context Recovery. Content-addressed store mapping compact references to exact original bytes or typed objects.Compressor
Engine component that transforms one recognized input shape into a smaller model-visible representation under declared policy.Context pack
SDK structure for assembling bounded context parts with provenance and policy.Fail closed
Unknown or invalid state rejects an operation or produces a safe non-success result. For transforms, the safe result is often the original input.Headroom
Modeled opportunity to reduce context or cost. It is inferred until stronger evidence exists.Hook
Code invoked by an agent lifecycle event, such as session start, prompt submission, or pre-tool execution.Inferred
Estimated by local model, tokenizer, or assumptions rather than confirmed by provider or verification method.List-price subtotal
Usage units multiplied by dated public catalog price. It is not a provider invoice.MCP
Model Context Protocol. Caveman uses a local standard-I/O server to expose compression, recovery, stats, and TOON operations to compatible agents.Observed
Recorded before/after relationship without enough control to establish cause.Pixel
Lossy text-to-PNG context encoding for explicitly allowed vision-capable models.Provider-reported
Usage or event data returned by model provider response.Record mode
Pass-through mode that observes local traffic without changing model-visible request bytes.Recovery handle
ccr_... content-derived identifier used to retrieve exact original bytes.
