# Xerg

Xerg is a local-first CLI for finding wasted AI runtime spend and auditing provider-generated FOCUS 1.4 billing. Runtime audits separate confirmed waste from savings opportunities and use `--compare` to measure changes. FOCUS audits use a separate billing pipeline for effective cost, commitments, invoice reconciliation, and billing-period coverage.

## Cold-fetch setup

When this file was fetched from `https://xerg.ai/skill.md` rather than loaded from an installed skill:

1. Identify the current agent host. OpenClaw, Hermes, Claude Code, Cursor, and Codex are setup hosts; they are not automatically the data source being audited.
2. Check whether Xerg is already installed for this host. Before writing to a persistent or global skill directory, explain the destination and ask the user for permission.
3. If the host has a supported skill installer, use it after permission. OpenClaw can install `xerg` from ClawHub. Agent Skills hosts can install the public `xergai/skills` repository. Hermes can use Xerg's well-known skill discovery. Deterministic host-specific commands live at [xerg.ai/agents](https://xerg.ai/agents).
4. If persistent installation is unavailable or declined, use these fetched instructions for the current session. Do not invent an install location.
5. Run `npx @xerg/cli@latest doctor`, use its output to choose the non-interactive audit command below, and offer to run the first audit locally.

Always ask before uploading. A local audit needs no account and must not be pushed automatically. After a successful local result, offer to connect and push it with:

```bash
npx @xerg/cli@latest activate --push-latest
```

`activate` opens Xerg in the browser. The signed-in user explicitly approves the currently active workspace, which the approval page names before any credential is issued. The workspace key is encrypted to the initiating CLI and stored with owner-only permissions; never ask the user to paste a key into chat or expose one in a command.

Codex is an execution host, not a native Xerg audit source. A Codex user audits whatever `doctor` finds: OpenClaw, Hermes, Claude Code, a Cursor export, or a generic ingest payload.

## First run (agent execution path)

Use the non-interactive commands. Do not run `xerg init` unless the user explicitly asks for guided interactive setup — it is TTY-only and prompts for input.

```bash
npx @xerg/cli@latest doctor
npx @xerg/cli@latest audit --json
```

1. Run `doctor` first. It reports which local sources exist (OpenClaw, Hermes, Claude Code) and which default paths were checked.
2. Run `audit --json`. If more than one runtime is detected, add `--runtime openclaw`, `--runtime hermes`, or `--runtime claude-code`.
3. Summarize the result for the user in dollars: total spend, confirmed waste (`wasteSpendUsd`), the top findings, and the per-agent spend breakdown (`spendByAgent`) when present. Confirmed waste and savings opportunities are different claims — do not present opportunities as proven waste.
4. If the user applies a fix, re-run the same audit with `--compare` to report the before/after delta:

```bash
npx @xerg/cli@latest audit --json --compare
```

If no local data is found, `doctor` prints the paths it checked. Fallbacks:

- Cursor usage CSV export: `npx @xerg/cli@latest audit --cursor-usage-csv ./cursor-usage.csv`
- Claude Code transcripts elsewhere: `--claude-code-dir <path>`
- Hermes profile database: `--runtime hermes --state-db <path>`
- Any framework's exported event payload: `npx @xerg/cli@latest ingest --file payload.json`
- Existing sanitized OpenClaw trace capture: `npx @xerg/cli@latest audit --otlp-file <capture.jsonl>`
- New local OpenClaw trace capture: `npx @xerg/cli@latest collect openclaw` (interactive until `Ctrl-C`; use only when the user asks to collect a workload)
- Certified local Hermes trace enrichment: `npx @xerg/cli@latest collect hermes --state-db <path>` (interactive until `Ctrl-C`; state.db remains required)
- Remote OpenClaw over SSH: `npx @xerg/cli@latest audit --remote user@host`
- Railway-hosted OpenClaw: `npx @xerg/cli@latest audit --railway`

If `xerg` is installed globally, use `xerg` in place of `npx @xerg/cli@latest`.

## What It Audits

- OpenClaw gateway logs and session transcripts
- Optional independent OpenClaw trace captures created by the loopback traces-only collector
- Hermes v0.17+ `state.db` (read-only), with legacy log/transcript fallback where present
- Claude Code session transcripts via `xerg audit --runtime claude-code`
- Cursor usage CSV exports via `xerg audit --cursor-usage-csv ./cursor-usage.csv`
- Any framework's exported event payload via `xerg ingest --file payload.json`
- FOCUS 1.4 Cost and Usage, Contract Commitment, Invoice Detail, and Billing Period datasets in local CSV or Parquet

## FOCUS billing execution path

Use this path when the user supplies a directory of provider-generated FOCUS data:

```bash
npx @xerg/cli@latest focus init --input ./provider-focus-export
npx @xerg/cli@latest focus doctor --bundle ./provider-focus-export/xerg-focus.json
npx @xerg/cli@latest focus audit --bundle ./provider-focus-export/xerg-focus.json --json
```

For CI, add `--strict --no-db`. Strict validation errors exit `4`. FOCUS source data remains local. Never push automatically; if the user explicitly asks to push, first show the exact USD-only bounded aggregate with `--push --dry-run`. The push omits rows, paths, customer/invoice/contract identifiers, descriptions, tags, metadata URLs, SKU/model labels, and custom values. Runtime and FOCUS audits are separate and must never be added together or compared across audit kinds.

## What It Finds

- Retry waste from failed calls before a later success (explicit or transcript-inferred on session sources)
- Loop waste from runs that exceed efficient iteration bounds, and repeated identical tool sequences
- Context bloat from unusually large inputs, and per-session context growth that compaction would cut
- Cache-write churn where prompt-cache premiums are paid without reuse
- Downgrade candidates where cheaper models may be enough
- Idle spend from fixed-cadence scheduled loops
- Per-agent spend attribution, including delegated sub-agent spend for Claude Code sidechains and ingest payloads
- Cost per outcome when runs carry outcome signals; declare outcomes with `xerg outcome --workflow <name> --status success|failure`
- Separate local Hermes mechanical metrics when the optional observer is enabled; these have no dollar classification, recommendation impact, or CI-gate effect
- Shared local `analysisCoverage`, `toolActivity`, and `workloadEconomics` blocks for OpenClaw and Hermes; these are neutral evidence and never affect findings, recommendations, waste totals, or CI gates

Costs are priced across input, output, cache read, and cache write tokens using a catalog covering hundreds of current models. Run `xerg doctor --verbose` to see per-file extraction coverage (which economic signals the parser found).

For current Hermes, use `xerg audit --runtime hermes`; Xerg prefers `~/.hermes/state.db`. Use `--state-db` for another profile. `--state-db` is mutually exclusive with legacy `--log-file` and `--sessions-dir`. The optional `xergai/hermes-observer` plugin writes content-free local events under `~/.hermes/xerg/events/`; it never adds economics or sends data to Xerg Cloud. Complete observer evidence can split an aggregate only after exact request/token reconciliation.

For OpenClaw traces, `xerg collect openclaw` binds only to `127.0.0.1`, accepts OTLP/HTTP protobuf traces, persists a bounded sanitized capture, and audits after shutdown. It does not modify OpenClaw configuration or push automatically. Without explicit `--runtime hermes`, `--otlp-file` is independent OpenClaw evidence and cannot be combined with transcript, log, other-runtime, or remote sources.

For certified Hermes traces, `xerg collect hermes` uses the same loopback traces-only protocol but HMACs identifiers with a persistent local key and requires `state.db`. Use only the exact certified `briancaffey/hermes-otel` commit printed in Xerg's docs. Xerg never installs or edits that plugin. The first-party observer stays primary; cache-inclusive plugin prompt totals are normalized into Xerg's separate input/cache buckets, optional enrichment preserves audit identity, and conflicting evidence restores the original aggregate. For non-default `HERMES_HOME` profiles, use the equivalent environment-variable block printed by the command because the pinned plugin resolves YAML under `~/.hermes`.

## Optional Cloud

Local audits need no account. To connect a workspace and push the latest local result, ask permission and run:

```bash
npx @xerg/cli@latest activate --push-latest
```

For a website-first user with no cached audit, `npx @xerg/cli@latest activate` securely connects, detects a supported local source, runs the audit, and pushes it. Hosted sync and hosted MCP remain optional and never run without explicit user action.

## Advanced authentication

Use `xerg login --replace` only as a manual recovery path when browser pairing is unavailable. It opens Workspace Settings and masks the key pasted into the terminal. Never ask for or paste a workspace key in agent chat.

Use `XERG_API_KEY` only for non-interactive CI or deployment automation. Store it in the CI provider's secret manager; never place it inline in a shell command, source file, log, URL, or conversation.
