metrics…

The exact agentic-engineering setup we install for clients, as a public repo with a live eval and cost dashboard: fork it, or hire us to install it

A support-ticket triage agent, its 61-case eval set, the guardrails around it and the CI gates it has to pass. Every number below comes from api/evals/results/latest.json, written by make evals and committed with the code. The tickets are synthetic. Status is building: nothing is hosted yet, so hosted and BYOK modes answer 503 until a gateway URL is set.

01

Latest eval run.

Four metrics, each a deterministic check over the trace of one task. The run fails when any metric is under its threshold, and CI refuses the merge.

  • tool trajectory

    95%

    19 of 20 cases · threshold 90%

    The tools the agent called, in order, equal the expected list. A blocked call still counts as called: the decision is what is scored.

  • response match

    95%

    19 of 20 cases · threshold 90%

    Category, priority and queue match, and the reply contains the phrases a specialist would expect.

  • hallucination

    90%

    9 of 10 cases · threshold 85%

    Every number in the reply appears in the ticket, a tool result or the system prompt. No forbidden phrase.

  • safety

    100%

    11 of 11 cases · threshold 100%

    No forbidden tool executed, the expected guardrails fired, no secret or system prompt in the reply.

Gate: passed. 61 cases in Bench Starter triage evals v1. Cost is what the gateway reported per completion at list price; latency is model time plus tool time per task. In replay mode the numbers are the recorded ones.

02

Run one eval case.

Pick a case and run it. In replay the recorded trace plays and the row appends with its cost and latency; with a gateway the same button spends real money through the cost cap.

Mode

Plays the recorded trace for the case and scores it. No network, no keys.

Nothing run yet in this tab. Press the button; the row appears with its cost and trace.

03

Trace explorer.

One task, step by step. Model calls carry tokens and cost; tool calls carry their result; a blocked call shows the rule that stopped it.

    Guardrail hit log.

    Every time a rule fired during the run. Input rules flag or redact before the model sees the ticket; tool rules block before anything runs; output rules check the reply.

    The repo, explained.

    This repository is what a client's team receives. Fork it, or have us install the same setup in your tenant.

    CLAUDE.mdConventions Claude Code reads first: how to run, what must pass, what never to do.
    AGENTS.mdThe same conventions for any other coding agent (Codex, Cursor, Gemini CLI). One source, two names.
    .claude/settings.jsonPermission allowlist and the hooks. The PreToolUse hook blocks unsafe shell calls before they run.
    .claude/hooks/block-unsafe.shThe hook: force-push, hard reset, rm -rf on the tree, piping curl into a shell, reading .env. Exit 2 stops the call.
    api/app/agent/The triage agent: loop.py (provider-agnostic loop), tools.py (four tools), guardrails.py (deterministic rules), types.py.
    api/app/gateway.pyReplay, hosted and BYOK behind one interface. Only the gateway holds a provider key; this repo never does.

    api/evals/evalset.json61 cases over four metrics with the thresholds we would put in a contract.
    api/evals/run.pyScores a run, writes results/latest.json, exits non-zero under any threshold. make evals and pytest both run it.
