handler/CHANGELOG.md

Changelog

All notable changes to handler are documented here. The format follows Keep a Changelog; versions are the v* tags the image workflows publish (plus latest from every push to main).

[Unreleased]

Added

• Activity screen in the mobile app (Settings → Manage → Activity): the control-command queue with status filters, per-row worker attribution (on <worker> / unclaimed), expandable result/error text, a Sweep CI action, and a 5s auto-refresh — the screen that answers "why is my login/spawn/sync stuck" from the phone.

Fixed

• Untrusted-workspace wedge on headless runs. Phase 4's tmux-path deletion also removed the only call to claude_config.ensure_onboarded, so agent working dirs — every fresh worktree — were never pre-trusted in ~/.claude.json and headless claude -p runs wedged or refused on the trust dialog with nobody at a TTY. Spawn and resume now re-seed onboarding + per-directory trust before every launch (resume included, so a cross-worker resume landing in a container that has never seen the working dir is covered). 2 regression tests.

Added — mobile app feature parity

The iOS app (app/) catches up with everything the backend and web dashboard gained since its last release:

• Model backend picker on spawn: the spawn form now offers the registered model backends (/claude/models) next to the Claude subscription, matching the web dashboard's per-spawn dropdown; the agent detail meta card shows which backend an agent is pinned to, plus its supervising worker.
• Headless run event stream: a new Events tab on the agent detail screen polls the cursor-paged /agents/{name}/events endpoint and renders the stream-json events live — assistant text, tool-call badges, run results with turns/cost, worker notices, raw lines.
• Schedules tab: list, create (interval, role, model backend, prompt), pause/resume, and delete recurring agent spawns across all projects.
• Memory tab: the agent-memory note graph (/memory/graph) with kind filters and expandable notes showing body, tags, and links — plus note authoring and deletion.
• The full management surface (Settings → Manage): model backends (CRUD incl. write-only API keys and the claude/pi harness pick), skills (incl. install-from-prompt), MCP connectors, plugins, permission overrides, repository registration (git-server + manual modes, mise-init), forge hosts (encrypted tokens, generated deploy keys), branch approvals, shared context, and the worker's claude /login flow — the phone no longer needs a laptop nearby.
• User accounts on mobile: the connect screen gains email sign-in against /auth/login (session token stored like the legacy env token), first-run admin setup, forgot-password, and an API-token fallback (auto-selected for servers predating accounts); Settings gains an Account screen (identity, change password, sign out with server-side revocation) and Manage gains the admin Users screen (invite with shareable links, promote/disable, reset links, delete).

Added — built-in operator skills, pre-installed on every deployment

Eight skills now ship inside Handler (handler.builtin_skills) and are seeded into the managed skill store on API startup, so every fresh install — and every existing deployment on upgrade — starts with the judgment layer the hard gates can't enforce:

• handler-quiet-output — work through tool calls, not prose: the transcript is not the deliverable. A minimized NOTES.md ledger records what happened and how, problems go to memory, status goes to the checkpoint, and questions go through the question tool (push notification + answer prompt in the web/mobile apps) — never typed into the transcript.
• handler-gate-recovery — respond to a blocked completion/push gate by fixing the real failure; never delete/skip tests, weaken the mise test task, or --no-verify.
• handler-testing — every behavior change lands with a test that fails without it; keep suites fast and deterministic.
• handler-checkpoints — checkpoints written for a phone-sized glance; questions only for operator-only decisions, with a recommended default.
• handler-memory — search before starting; save gotchas/decisions/runbooks, not narration or secrets.
• handler-mise-tasks — mise run test is the verification contract; never narrow it to get green.
• handler-scheduled-runs — the read-state-file → one increment → overwrite-state-file continuity pattern for recurring runs.
• handler-secrets — injected credentials stay out of logs, commits, PRs, and memory.

Seeding is idempotent by name: operator edits/disables survive every upgrade; deleting a built-in restores it (as shipped) on the next API start. 6 new tests (406 total).

Added — user accounts: email sign-in, invites, resets, per-user separation

• Email + password accounts replace "know the API key" for humans. First run shows a setup form and the first account created is the admin; every later account is invited by an admin through a one-shot set-password link. Passwords are scrypt (stdlib, self-describing hashes); sessions are opaque bearer tokens stored only as SHA-256 with a configurable TTL.
• Password reset by email (POST /auth/forgot → short-lived link, silent about account existence) via plain SMTP (SMTP_* settings). Email is optional: with SMTP unset, invite/reset links are shown to the admin in the dashboard to hand over out-of-band. Spending a link revokes the account's existing sessions.
• Per-user separation of projects, skills, and tools. Projects, skills, MCP connectors, plugins, and model backends gain an owner; users see shared + their own (foreign resources 404 — existence isn't leaked), owners operate their own projects end-to-end without admin, shared (unowned) rows stay admin-managed and visible to all. Launches materialize only the project owner's skills/connectors, and private model backends can't be picked for someone else's spawns or schedules. Deleting a user reassigns their resources to shared; admins can reassign owners.
• Users page in the dashboard (admin-only): invite, admin/disable toggles, reset links, delete. Sign-in page gains first-run setup, forgot-password, and a raw API-token fallback; /reset is the public landing page for invite/reset links.
• Admin safety rails: the last active admin can't be demoted/disabled/deleted; no self-deletion. AUTH_TOKEN/ADMIN_TOKEN/SHARED_CONTEXT_WRITE_TOKEN keep their exact historical semantics for scripts/CI and break-glass.
• 24 new tests (auth flows + separation matrix; 397 total).

Database (user accounts)

• Migration 0016_user_accounts: new users, auth_sessions, auth_tokens tables plus a nullable owner_user_id on projects, claude_skills, claude_connectors, claude_plugins, claude_models. Purely additive; existing rows have no owner (= shared) so an upgraded deployment behaves exactly as before until accounts are created.

Deployment notes (user accounts rollout)

1. Apply migrations as usual (the API container runs them on start).
2. Optionally set SMTP_HOST/SMTP_PORT/SMTP_USERNAME/SMTP_PASSWORD/SMTP_FROM (+ SMTP_STARTTLS/SMTP_SSL) and PUBLIC_BASE_URL for emailed links; without them, invite/reset links appear in the dashboard instead.
3. Open the dashboard and create the first account — it becomes the admin. Existing AUTH_TOKEN-based scripts keep working unchanged; the token can be rotated or dropped once accounts exist (keep one as break-glass if you like).
4. New TTL knobs (optional): SESSION_TTL_DAYS=30, RESET_TOKEN_TTL_HOURS=2, INVITE_TOKEN_TTL_HOURS=168.

Added — the pi harness for local models (#29)

• harness on model backends (claude | pi, default claude). A backend row can now run its agents through the lightweight pi coding agent instead of the claude binary. pi speaks the OpenAI Completions API natively, so a bare local endpoint (vLLM, llama.cpp, Ollama) works without a LiteLLM / claude-code-router translation proxy — and the loop is far lighter for slow local token throughput. Selectable in the dashboard's Claude → Models form and via POST /claude/models.
• Full gate parity on pi via a bundled bridge extension (pi_bridge.ts, generated into a per-agent PI_CODING_AGENT_DIR under ~/.handler-pi/, outside the repo tree). All gate logic stays in the same tested Python hooks:
  • Stop/completion gate (tests green + committed + pushed) re-prompts pi with blockers;
  • git push runs the test → image-build → protected-branch approval chain and denies on failure; forge merge / mise run deploy hit the approval gate;
  • questions defer through a new ask_operator tool into the normal answer/resume flow;
  • memory recall injects at session start; memory_search/get/save/link are registered as native pi tools (pi has no MCP) through python -m handler.mcpserver --call.
• Web tools for agents: web_search and web_fetch (handler.webtool), registered on pi-harness agents. Fetch is provider-free (HTML stripped to readable text, size-capped). Search resolves SEARXNG_URL → BRAVE_SEARCH_API_KEY → a zero-config DuckDuckGo fallback.
• Full built-in tool surface on pi: read, write, edit, bash plus grep, find, ls (off by default in stock pi) — 14 tools total including the handler set.
• Skills + prompts on pi: pi discovers the same web-managed ~/.claude/skills sync and the repo's committed .claude/skills (forge role skills); handler conventions are appended to pi's system prompt; AGENTS.md / CLAUDE.md are read natively.
• Cross-worker resume for pi sessions: single-JSONL transcripts pre-assigned by handler, archived/materialized through the existing session_archives flow.
• PI_BIN binary override; SEARXNG_URL / BRAVE_SEARCH_API_KEY settings; a fake_pi test binary and 22 new tests (370 total).

Changed

• Control image: Node bumped from NodeSource 20 to 22 (pi requires ≥ 22.19; Claude Code needs ≥ 18, unaffected) and @earendil-works/pi-coding-agent is baked in alongside the Claude Code CLI.
• control.models refactored: resolve_model() returns the row + decrypted key and harness_of() / claude_env() split harness selection from env building. resolve_model_env() keeps its signature (claude rows unchanged; pi rows return {}).
• Dashboard Models form gained the harness selector and a pi harness badge; docs (docs/local-models.md, README) describe both harnesses.

Database

• Migration 0015_model_harness: adds claude_models.harness (NOT NULL DEFAULT 'claude'). Purely additive — every existing backend row keeps its current behavior. Applied automatically by the API container on start (RUN_MIGRATIONS stays false on control, as before).

Deployment notes (for this release's rollout)

Merging to main publishes both images (docker.yml → ghcr.io/0xwheatyz/handler, docker-control.yml → ghcr.io/0xwheatyz/handler/control). To roll out:

1. Pull both images and restart API before control (compose already orders this): the API applies 0015_model_harness on boot; the control worker only needs the new column to exist when a pi backend is first selected.
2. The control image must be the new build before spawning any pi-harness agent — it carries the pi binary and Node 22. Older control containers refuse cleanly (launch fails loudly, no silent fallback to the subscription).
3. No env changes required. Optional: SEARXNG_URL or BRAVE_SEARCH_API_KEY on the control container for a real web_search provider (unset = DuckDuckGo fallback); PI_BIN only if pi lives off PATH.
4. Existing agents are untouched: subscription and claude-harness agents launch exactly as before; running agents and their resumes are unaffected by the migration.
5. Rollback: reverting the images is safe — the harness column is ignored by old code. Only agents already pinned to a pi backend would fail to resume until the new control image returns (alembic downgrade would drop the column; not needed for an image-level rollback).
6. Volume/layout invariants unchanged: same PROJECTS_ROOT, same HANDLER_SECRET_KEY everywhere, no new shared filesystem. pi state lives under the worker's $HOME (~/.handler-pi/) and sessions ride the existing DB archive flow.

Verification

• 370 tests green (SQLite, real alembic upgrade head per test), including the new fake_pi runner suite and mocked web-tool provider tests.
• The bridge was validated live against pi 0.84.1 with a stub OpenAI endpoint: memory injection, push-gate denial (including protected-branch approval), the stop-gate block loop, ask_operator pause/resume, and the 14-tool surface all ran end to end through the real hooks and database.

Earlier work (pre-changelog)

Phases 1–2 plus the web dashboard, headless runner, credential store, schedules, model backends, skill install-from-prompt, and the agent memory layer predate this changelog; see docs/PLAN.md and the merged PR history for their details.
