Three product actions: scan_tool (pre-call), inspect_response (post-call), scan_full (full lifecycle). Optionally evaluate context trust — detecting truth debt in workspace goals, decisions, tasks, and evidence — before agents act on stale or incomplete data. ActionLedger separates observed facts from inferences and assumptions, then returns a recommendation with verdict confidence and supporting evidence where available. Agent risk is multi-surface — ActionLedger classifies whether risk appears in the prompt, tool call, response, destination, memory/context, peer delegation, skill/capability, or a compositional multi-step chain. Background agent workflows require stronger upfront structure. ActionLedger can evaluate whether a task has a clear goal, authorization matrix, fallback plan, output format, review triggers, and budget boundaries before the agent runs. Memory is now an action surface. ActionLedger can review proposed memory writes for source quality, sensitivity, conflicts, overwrite risk, and human-review requirements. Agent risk appears throughout the loop: goals, context, planning, tool calls, memory reads/writes, peer handoffs, external destinations, observations, and final outputs. ActionLedger classifies the stage and applies the right trust decision before the action proceeds. Instructions are part of the agent risk surface. ActionLedger can review system prompts, project instructions, custom instructions, and task prompts for scope, permissions, missing constraints, context bleed risk, and human-review requirements. ActionLedger can review prompt contracts before agents act, checking whether instructions define scope, outputs, boundaries, tool policy, verification, fallback behavior, and review triggers. Autonomous agent goals need measurable finish lines. ActionLedger can review goal contracts for done conditions, verification methods, constraints, stop conditions, progress tracking, fallback plans, and review triggers before execution.","authentication":{"header":"x-api-key","test_key":"test-key-123","note":"Include x-api-key in all scan and history requests."},"curl_examples":{"scan_trusted_domain":"curl -s -X POST $BASE_URL/api/scan_tool -H 'Content-Type: application/json' -H 'x-api-key: test-key-123' -d '{\"url\": \"google.com\"}'  #
