cekura-flag-call-log-failures

cekura-flag-call-log-failures is a skill for Claude Code from cekura-ai/cekura-skills. It costs 229 tokens per session (3,608 once invoked), scanned A, original, MIT.

A read-only tool for reviewing recent production call logs from an AI voice agent. It identifies calls that failed specified goals and groups all calls into separate outcome categories.

In plain words
What is it for?
Use it to find failing call IDs, calculate failure percentages, provide evidence, and create an overall outcome distribution for quality reports or follow-up tests.
Why use it?
It shows which failures are caused by the agent and how common they are across all reviewed calls. Caller-side disconnects and recovered calls are kept separate from agent failures.

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

cekura-flag-call-log-failures 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 — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

flag-call-log-failures

Go through an agent's recent production call logs and produce three things:

  1. Flagged calls — the call IDs that hit each specified KPI/issue/goal failure, with verbatim evidence.
  2. Failure rates — what percentage of all reviewed call logs each failure represents.
  3. Outcome distribution — every remaining call bucketed into a mutually-exclusive outcome taxonomy (e.g. not-answered / vetted / non-vetted caller-side / non-vetted agent-issue), with per-bucket percentages, so the flagged failures are framed against the whole population.

It is the triage front-end: hand the flagged set to cekura-generate-scenarios to build evaluators, or give the user the distribution for a customer-facing quality report.

This skill is strictly read-only — it never creates, updates, or deletes anything.

The single most important job is attribution: a call is an agent failure only when the agent under test caused it. Caller-side endings, simulated-caller disconnects, and recovered calls must NOT be counted as agent failures — they belong in their own buckets.


Step 0 — Prerequisites

Reads through the Cekura MCP. Confirm these are present:

  • mcp__cekura__aiagents_retrieve — agent description + intended behavior (the yardstick for "failure")
  • mcp__cekura__call_logs_list — paginated production call list (lightweight: usually has id, duration, call_ended_reason, success, rolled-up metric scores — but often no transcript)
  • mcp__cekura__call_logs_retrieve — full transcript + metric evaluations for a single call
  • mcp__cekura__metrics_list — to find metrics that already grade the KPIs/issues (reuse these as the classification basis when they exist)

If the mcp__cekura__* tools aren't connected, stop and tell the user to connect the Cekura MCP (see /setup-mcp or https://docs.cekura.ai/mcp/overview).


Step 1 — Inputs

Use AskUserQuestion for anything not supplied:

  1. Agent ID (numeric). If unknown, mcp__cekura__aiagents_list helps find it.
  2. (Optional) Project ID.
  3. Window — how many recent calls (default 100) or a date range. Process in batches (see Step 2).
  4. KPIs / issues / goals to measure — the heart of the request:
    • Explicit issues — e.g. "calls that ended before all vetting questions", "agent looped on an unclear answer", "background noise stalled the agent". Each becomes a flag bucket + a failure-rate number.
    • A KPI / goal — e.g. "every call should fully vet the candidate", "what % of answered calls can we improve" — which you invert into the failure(s) that break it.
    • Nothing specific"any genuine agent failure," grounded in agent_description, classified against the failure-mode taxonomy in Step 3.
  5. Outcome taxonomy — the mutually-exclusive buckets to distribute ALL calls into. Derive these from the agent's job. For a candidate-vetting agent the natural set is:
    • not answered · vetted · non-vetted — caller-side · non-vetted — agent/system issue

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.
