Analyze a raw prompt, detect ambiguities, compile an optimized version, score quality, and estimate cost across providers. Returns a PreviewPack for review.

Refine a prompt by answering blocking questions or providing manual edits. Re-runs analysis and returns updated PreviewPack.

Full pre-flight analysis: classify task, assess risk, route model, score quality. Returns complete decision bundle. Metered — counts as 1 optimization use.

Quick pass/fail check of a prompt. Returns score, top issues, and a suggestion. No compilation, no session.

Approve the compiled prompt. Returns the final optimized prompt ready for use.

Estimate token count and cost across providers for any prompt text. No session needed.

Compress context (code, docs) by removing irrelevant sections. Returns pruned context with token savings.

Classify a prompt by task type, reasoning complexity, risk level, and suggested profile. Free — no metering.

Route to the optimal model based on task complexity, risk, budget, and latency preferences. Returns recommendation with decision_path audit trail. Free — no metering.

Get aggregated optimization statistics: total count, average score, top task types, estimated savings.

Score and rank MCP tools by relevance to a task intent. Optionally prune low-relevance tools to save context tokens.

Configure optimizer behavior: mode, threshold, strictness, default target, ephemeral mode, session limits. Supports config locking with passphrase protection.

Get current usage count, limits, remaining quota, and tier information.

Activate a Pro or Power license key. Validates the Ed25519 signature offline and unlocks the corresponding tier.

Check current license status, tier, and expiry. Returns purchase link if no license is active.

Save custom governance rules to the local rules file (~/.prompt-control-plane/custom-rules.json). Validates all rules against the product schema, writes to disk, and returns the rule-set hash. Rules take effect on the next optimization. Works with any LLM connected to PCP. Enterprise tier only.

List all optimization sessions with metadata (no raw prompts). Free tool, not metered.

Export full session details including raw prompt. Free tool, not metered.

Delete a single optimization session by ID. Returns deleted status. Free tool, not metered.
