The one-time environment setup command (LLMs, certs, GitHub) is now
`arc install`, freeing up naming space for a future `arc init` command
for per-project initialization.

When no explicit provider is set on a request, resolve_provider now
consults the model catalog (e.g. gpt-5.4 → openai) before falling back
to the client's default provider. This fixes PR description generation
sending cross-provider model IDs to the wrong provider.

Standalone subcommand that creates SSH credentials for a run's Daytona
sandbox and connects directly (or prints the command with --print).
Also parameterizes create_ssh_access TTL instead of hardcoding 60 min.

In verbose mode, completed tool call bars accumulated in indicatif's
MultiProgress without limit. After ~80+ bars exceeded the terminal
height, indicatif's cursor repositioning broke and all rendering stopped.
Now in verbose mode, completed tool calls are printed as permanent output
via multi.println() and their bars are removed from MultiProgress. Only
running tool calls remain as live bars with spinner + elapsed time. This
keeps MultiProgress small regardless of how many tool calls execute.

Provides CLI access to preview URLs for ports exposed by Daytona sandboxes.
Supports standard (URL + token + curl), signed (self-contained URL), and
--open (browser launch) modes.

Remove --fail-with-body from curl so the response body (including error
JSON) is always captured. Previously, set -e killed the script at the
curl line on non-2xx responses before the error-checking code could run,
leaving the agent with an opaque exit code 22 and no actionable message.

Replace Gemini API with OpenAI /v1/images/generations endpoint in the
imagegen script. Remove unsupported response_format parameter (gpt-image-1
returns b64_json by default). Add standalone imagegen-openai workflow for
testing image generation independently.

Per-run data now lives in ~/.arc/runs/ while daily CLI log files
stay in ~/.arc/logs/. Renames: logs_root → run_dir (RunConfig field,
Handler trait param, all handlers), logs_dir → run_dir (CLI arg,
local variables), default_logs_base → default_runs_base (path fn).
Adds DB migration 002 to rename workflow_runs.logs_dir → run_dir.

Adds a switchable tracing layer that writes to ~/.arc/logs/{run-dir}/cli.log,
so all diagnostic info for a run is co-located with its other artifacts instead
of buried in the shared daily log file.

The Playwright MCP server provides a browser_install tool, so we can
drop the separate command node and let the agent install the browser
via MCP instead.

Use npx directly instead of npm install, which fails due to the repo's

The GitHub App check was gated behind #[cfg(feature = "server")] so it
never ran in CLI-only builds. It also only checked whether env vars were
set, not whether the key could actually sign JWTs.
- Move GithubAppStatus and check_github_app out of the server feature gate
- Try sign_app_jwt to validate the private key, catching corrupt keys
- Show app_id and slug in doctor output
- Keep server-only fields (client_id, client_secret, webhook_secret)
behind #[cfg(feature = "server")]

Port the OpenAI Codex develop-web-game skill (Playwright-based game dev
loop) into skills/develop-web-game/ with paths adapted for Arc's
workspace-relative skill discovery. Add a web-game-demo workflow that
verifies the skill and its asset files (playwright client script,
action payloads JSON) are properly discovered and accessible in a
Daytona sandbox.

Arc API, Arc Web, GitHub App, and cryptographic key checks are only
relevant when the server feature is enabled. Without this gate, `arc
doctor` showed misleading connectivity errors for services that cannot
even be started.

When the sandbox does not support preview URLs (e.g., local sandbox),
fall back to http://localhost:{port} instead of erroring. This makes
the sandbox MCP transport work transparently on both local and remote
(Daytona) sandboxes.

- docs/agents/mcp.mdx: Remove pre-release warning. Add sandbox transport
docs alongside stdio and HTTP. Restructure configuration section to
cover both cli.toml and run config TOML. Replace filesystem example
with Playwright browser automation example.
- docs/execution/run-configuration.mdx: Add [mcp_servers] section with
field reference for all three transport types. Add to full example.
- docs/reference/cli-configuration.mdx: Add sandbox transport subsection.
Cross-reference workflow-level MCP config.
- docs/integrations/daytona.mdx: Add MCP sandbox transport to feature table.

Wire MCP server configs from workflow TOML into agent sessions so
MCP tools are available to agent stages during workflow runs.
Changes:
- run_config.rs: add mcp_servers HashMap to WorkflowRunConfig
- backend.rs: AgentApiBackend.with_mcp_servers() passes configs to SessionConfig
- run.rs: extract mcp_servers from RunConfig and pass to backend
- demo/mod.rs: add default mcp_servers field to struct literals
New workflow: arc/workflows/playwright-demo/
- Runs on Daytona with daytona-medium snapshot
- Configures Playwright MCP as a sandbox transport (port 3100)
- Agent browses Hacker News, takes screenshots at each step
- asset_globs captures screenshots/** into logs directory

Adds McpTransport::Sandbox variant that starts an MCP server inside the
sandbox, waits for it to listen, gets a Daytona preview URL, and rewrites
to HTTP transport for the MCP client connection.
Key changes:
- Sandbox trait: add get_preview_url(port) for authenticated port access
- DaytonaSandbox: implement get_preview_url via Daytona SDK preview links
- McpTransport::Sandbox: new variant with command, port, env fields
- Session: resolve_sandbox_mcp_servers() starts servers and rewrites to HTTP
- Integration test: end-to-end Playwright MCP in Daytona - navigates to
example.com and verifies "Example Domain" in accessibility snapshot
Config example:
[mcp_servers.playwright]
type = "sandbox"
command = ["npx", "@playwright/mcp@latest", "--port", "3100", "--headless"]
port = 3100

Expose the Daytona SDK's ComputerUseService through DaytonaSandbox so
callers can start the virtual desktop, take screenshots, and interact
with mouse/keyboard programmatically.
The new integration test validates the full flow: start the desktop
environment, launch Chromium on DISPLAY=:0, and capture a screenshot
of example.com via the Computer Use API.

Warn users that exe.dev and devcontainer features are under active
development and may require special build flags.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The Exe sandbox variant, its config field, and all arc_exe usage in
arc-workflows are now behind #[cfg(feature = "exedev")]. Default CLI
builds skip arc-exe and openssh entirely. arc-api enables exedev since
its demo module constructs full SandboxConfig structs.

cargo build / cargo build --release now only compiles arc-cli and its
transitive deps, skipping arc-api, arc-slack, arc-db, arc-types, sqlx,
axum, etc. Use --workspace to build everything.

CLI-only builds no longer pull in arc-api and its heavy server
dependencies (axum, tower, hyper, sqlx, arc-db, arc-types) unless
the server feature is explicitly enabled.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Centralizes config types (ServerConfig, CliConfig, expand_tilde) into a
new arc-config crate. Makes arc-api an optional dependency of arc-cli
behind a default-on "server" feature flag, so CLI-only builds skip heavy
server deps (axum, tower, hyper, sqlx, arc-db, arc-types).

Drop session before awaiting event_writer_handle to close the
broadcast channel, preventing a deadlock where the spawned task
waits for senders to drop while session is still alive.
Move subscribe() before initialize() so the SessionStarted event

- Reject negative durations in parse_duration (i64 -> u64) to prevent
future cutoff that would delete everything
- Remove orphans flag from has_explicit_filters since --orphans is
additive, not restrictive, and shouldn't disable the 24h staleness guard
- Use parsed label_filters instead of raw args.filter.label so malformed
labels that get silently dropped don't incorrectly disable staleness
- Replace derived Serialize with custom impl delegating to Display for
RunStatus, fixing JSON serialization (was producing null/tagged objects
instead of flat strings)
