The first five render `ak status` health and routing; Usage indexes local Claude/Codex/OpenCode transcripts on demand and can display a separately cached OpenRouter account-analytics block. That block never changes local transcript/session/host totals; the dashboard itself never fetches it. Live groups work by project, then host-branded root sessions with nested agent/worker threads and independently evidenced provider/model metadata, and pairs an interactive agent/tool execution canvas with a rich, server-masked transcript stream. Active sessions can be followed live or reviewed with synchronized play/pause/seek; completed sessions remain available for bounded playback. Live contains no chat or control plane. Ruflo, agentic-qe, and dual-run stores are not auto-discovered; register each trusted structured JSONL file with repeatable `--live-source 'surface=path'` (`surface` is `ruflo`, `aqe`, or `dual-run`). The page is self-contained and offline-first (no internet fetches; local files and loopback subprocesses/endpoints only). A fresh **per-session token** is minted at startup and required by every `/api/*` route (`x-dash-token` header; the launch URL carries it in the `#` fragment, same contract as `ak admin` — ADR-0007, ADR-0014) — this page serves full transcript text, so it is gated the same way admin already gated GitHub/npm stats. See [Live Sessions](docs/LIVE-SESSIONS.md) for coverage, syntax, and privacy limits. **Auto-opens your browser** (`--no-open` for headless/SSH); `--port N` changes the port; tabs deep-link (`#live`) and persist. Stop with Ctrl-C. (Also available as `ak x dashboard`.) | | **usage** | Reads provider-account analytics from local cache (`ak usage status`) or performs one explicit OpenRouter management-API refresh (`ak usage refresh openrouter`). Refresh requires `OPENROUTER_MANAGEMENT_KEY`, writes a credential-free mode-`0600` cache, and discards endpoint/user/key/session identifiers. `status` and dashboard reads make no network request. OpenRouter account rows have no grounded host/session/project correlation and are never merged into transcript totals. | | **admin** | Opens the **maintainer admin** (`127.0.0.1:7432`, localhost-only, foreground) — the project-telemetry sibling of `dashboard`, with the same dark/light visual theme and persisted theme preference: unique repo visitors and cloners (GitHub traffic API, needs a push-access token via `GITHUB_TOKEN`/`GH_TOKEN`/`gh auth token` — panels degrade honestly without one), contributors and watchers, npm download momentum (last 7d vs prior 7d, sparklines — shown as trend only, never an absolute reach number, since mirrors/CI inflate the raw count), latest CI run status and open Dependabot alerts, a **"since you last looked"** delta strip over a local baseline, open issues/PRs from others (oldest first), and external humans ranked by recency (bots excluded). Access is gated by a **per-session token** carried in the URL fragment and sent header-only; the page makes **zero external fetches** (the server proxies GitHub/npm; your credential never reaches the page or the payload — ADR-0007, ADR-0013). Where `dashboard` is offline-first, `admin` does deliberate GitHub/npm egress — that contract split is why they're siblings, not tabs. `--port N`, `--no-open`; Ctrl-C stops.

The plumbing spelling is `ak x host`. `ak provider` and `ak x provider` are deprecated compatibility aliases that warn on stderr and will be removed before the stable release. | | **uninstall** | Removes the kit's footprint (and any legacy shell-kit install); project data is never touched; `--purge` also offers to remove the global packages. | diff --git a/docs/adr/0018-generalized-host-worker-execution.md b/docs/adr/0018-generalized-host-worker-execution.md index cca793f..190d4d1 100644 --- a/docs/adr/0018-generalized-host-worker-execution.md +++ b/docs/adr/0018-generalized-host-worker-execution.md @@ -3,7 +3,7 @@ - **Status:** Accepted - **Date:** 2026-07-29 - **Updated:** 2026-07-30 -- **Update note:** Hardened trusted-policy validation, adapter invariants, plan guards, and bounded worker teardown. +- **Update note:** Added private bounded dependency handoffs and one absolute lifecycle deadline per attempt. - **Deciders:** agentic-kit maintainers ## Context @@ -34,7 +34,7 @@ permission-response contract required for a routable worker.
