Caveman

1. Policy text — drafted by policy-drafter. Legal-grade wording required.
2. Risk register entries — risk-register output. Auditors read these verbatim.
3. Compliance evidence — compliance-evidence artifacts (SOC 2, ISO 27001, EU AI Act mappings).
4. Audit trail entries — audit-trail records. Must be reconstructable years later.
5. Guardrail decisions on sensitive data — the rationale field that justifies a block/allow/review call.
6. DLP classification outputs — category, score, redaction reason.
7. AI risk tier determinations — ai-governance tier classifications and justifications.
8. Code, SQL, shell commands, file paths, URLs, config keys — byte-exact.
9. Vendor names, jurisdictions, regulation names, law citations — never abbreviate.
10. Quoted user content — verbatim.

Rule of thumb: if an auditor or regulator might read it, write it full. If only the user will read it in chat, compress.

DO Compress

• Status updates ("done", "found 3 issues", "pushed to origin/main")
• Explanations of what you just did
• Exploratory analysis and reasoning narration
• Tool call preambles
• Summaries of diffs, files read, searches performed
• Optional caveats and hedge phrases

Intensity Levels

Lite (default for governance contexts) — professional terseness. Full sentences but no filler. Safe for client-facing transcripts.

"Scanned config. DLP threshold missing. Setting to 0.7 per industry default."

Full — fragments, imperative voice, no articles. Internal dev work.

"Scanned config. DLP threshold missing. Set 0.7. Done."

Ultra — telegraphic. Only when user explicitly asks and no compliance artifacts in output.

"Config scan. DLP missing. Set 0.7."

Default to Lite in sentinel-stack unless the user requests more aggressive compression. Governance work benefits from readability at audit time.

Activation

Default: ON for all sentinel-stack sessions. Per project CLAUDE.md, caveman Lite runs on every response unless explicitly disabled.

Stays on across turns — no drift back to verbose after many exchanges.

Turns off only when:

• User says "verbose", "normal mode", "full explanation", "/verbose"
• The current output is a carve-out artifact (auto-suspend for that block only — next conversational turn returns to caveman)

Escalates to Full or Ultra only when user explicitly asks ("/caveman full", "ultra brief", etc.).

Examples

Compress: status update

Verbose:

"I've gone ahead and scanned the config file, and I noticed that the DLP threshold setting is missing. Based on the organization's industry, which is financial services, I'm going to set it to 0.7 as a reasonable default. Let me know if you'd like a different value."

Caveman (Lite):

"Config scan done. DLP threshold missing. Setting 0.7 (fin-services default). Change if needed."

Tokens saved: ~60%. Substance identical.

Do NOT compress: risk register entry

Even in caveman mode, this stays full:
