linecanary-monitor is a skill for Claude Code, Codex from CALLE-AI/awesome-phone-call-agents. It costs 76 tokens per session (1,106 once invoked), scanned A, original, MIT.

A monitoring workflow that makes scheduled test calls to a business phone line or voice agent, checks expected answers and timings, and reports changes from earlier results.

In plain words

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

linecanary-monitor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

LineCanary Monitor

Use this skill when the user cares about a phone line staying healthy: an IVR menu, an AI receptionist, a front-desk line — anything customers dial.

It drives the runnable linecanary app, which places at most one CALL-E call per check per invocation, validates the structured result against operator-written assertions, compares timing and answers against the line's own history, and exits 0/1/2 for automation.

When to use

  • "Is our phone line / voice agent still working?" — run the checks live and interpret the report.
  • "Watch this line" / "monitor our IVR" — set up config, verification and a host schedule (cron or GitHub Actions; the app never self-schedules).
  • "Did the voice-agent deploy break anything?" — run the smoke check (--only <check-id>) after a deploy, gate on the exit code.
  • "Why did the canary page?" — read the JSON report and the baseline history, explain the regression kinds in plain words.

When not to use

  • The line belongs to someone else and the user cannot verify ownership or produce a written authorization. LineCanary refuses unverified lines; do not help work around that — it is the product's compliance boundary.
  • The user wants outbound calls to customers, leads or arbitrary businesses. That is not monitoring; decline and point at the safety notes.
  • Sub-minute check frequency or bulk parallel probing. See references/safety.md — keep schedules proportionate (15–60 minutes is the intended shape).

How it works

  1. Config as code: linecanary.config.json declares lines (with an ownership block), checks (task + strict resultSchema + assertions + timing bounds + confidence floor) and alerting. Full semantics in references/config-reference.md.
  2. Ownership verification: a greeting_code line is verified by one call that must hear the operator's code in the line's own greeting; client lines under written authority use attestation. Verification is pinned to the phone number — a changed number re-verifies.
  3. Every run is dry-run by default and prints the plan without dialing. --live places the calls, evaluates, diffs against the baseline history and appends to it. Every call opens with an AI disclosure.
  4. Exit codes: 0 healthy · 1 regressions or failing checks · 2 the run itself broke (config, credentials, API). Treat 1 as "page a human", 2 as "the monitoring is broken, not the line".

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

linecanary-monitor is a skill published in the GitHub repository CALLE-AI/awesome-phone-call-agents (88 stars, last pushed yesterday), licensed MIT. It adds 76 tokens to every session and 1,106 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
