ACR — Agent Composition Records

Acknowledge an anomaly signal notification after reviewing it with your operator. Records that the notification has been reviewed. Acknowledgements expire after 30 days. Does not remove the observation from the network — only records that you have reviewed the signal.

Query the friction lens of your interaction profile — one of several lenses available (more on the roadmap). The friction lens surfaces where time and tokens are being lost: chain overhead, directional amplification between targets, retry waste, population drift, and per-target bottlenecks. Friction is a continuum, not a verdict — high friction could be infrastructure, a hard task, or a component with elevated anomaly signals. Use it together with anomaly signal notifications to interpret correctly. Capture is automatic via the host-side hook (@tethral/acr-hook); the report defaults to source='all' so it reflects every captured call. Pass source='agent' for your log_interaction self-reports only, or source='server' for the MCP observer self-log only.

Identity card for your ACR agent: agent ID, API key, dashboard link, provider class, status. Pure identity — for "what should I do next?" call `orient_me`; for behavior data call any lens tool directly.

An anomaly signal is a behavioral pattern ACR observed across multiple unrelated agents (not a security event). Check for unread anomaly signal notifications about components in your composition. If ACR has observed anomaly signals affecting a skill, MCP, or system you use, it will have sent a notification here. Also delivers version updates. Call this on startup. ACR is a registry and notification layer, not a security check — notifications reflect what the network observed, not a verdict.

Enrich your ACR interaction profile with a manually-reported receipt. Use this for signals the host-side observer cannot infer on its own — chain structure, decision tokens, substitutions, whether the result was actually used. Primary capture is the host-side observer: install @tethral/acr-hook as a Claude Code PreToolUse/PostToolUse hook (or the equivalent for your host) and every tool call your agent makes is recorded automatically, with no LLM cooperation. The hook gives you target + status + duration; this tool is how you add the structured signals the hook can't see. Good moments to call log_interaction: - A multi-step workflow you want the friction lens to analyze as a chain — pass chain_id, chain_position, preceded_by. - A call that replaced a failed one to a different target — pass substitution_of so the substitution-graph lens can learn the swap. - A call whose response you discarded — pass result_used=false to seed the wasted-attention lens. - Reasoning tokens spent deciding *which* target to call — pass decision_tokens. - A call that seemed wrong but didn't fail outright — pass anomaly_flagged=true with a content-free anomaly_detail. If you have not installed the hook yet, this tool can also serve as the only capture path — but expect lens views to be sparse, because LLMs don't reliably self-report every call. Classification fields (all optional, all content-free): activity_class ("language", "math", "visuals", "creative", "deterministic", "sound") and other category fields (target_type, interaction_purpose, workflow_role, workflow_phase, data_shape, criticality) describe the kind of work this call represents. Richer classification unlocks friction breakdowns by kind-of-work as agents specialize. ACR collects interaction metadata only (target names, timing, status, descriptive classifications). No request/response content is collected. We do not track the agent's owner. Terms: https://acr.nfkey.ai/terms

Where am I, and what should I do next? Reads your profile, coverage, and unread signals, then returns the single most useful next step for your current state (just registered / some data / steady). Call this when you're unsure where to start.

[DEPRECATED — call `orient_me` instead.] One-call snapshot of profile, friction, and coverage. Superseded by `orient_me`, which routes by state and surfaces the same lens summaries when the agent is steady. Will be removed in a future release.
