Awman

awman

awman is a Rust CLI and TUI for running AI coding agents (Claude Code, Codex, OpenCode, and others) in isolated Docker or Apple Containers sandboxes. It coordinates parallel agent sessions, executes multi-step workflows, and exposes a REST API for headless programmatic control.

awman is not a tmux wrapper. The name invites that assumption. awman ships its own tab-based TUI with its own keybindings. Tmux is not a dependency.

awman was previously named amux. See "Migrating from amux" below.

Prerequisites

A container runtime, set via the global-only runtime config key (awman config set --global runtime <value>, then awman ready):

docker-sbx-experimental (new in 0.10.0) runs each session in a dedicated microVM — private kernel, filesystem, and Docker daemon. It does not honor dir(), skill, or context overlays; networking goes through an HTTP/HTTPS proxy (raw TCP/UDP blocked); sandboxes persist between sessions. The runtime must be running and healthy before any awman session starts. This runtime requires a free Docker account; sbx login is a one-time authentication step that must complete before awman ready reports the runtime healthy.

Install

Mise is the recommended install path. It manages the version, pins reproducibly, and uses the GitHub releases backend — no extra dependencies.

A ready-to-copy pin lives at templates/0.11.0/mise.toml in this skill — copy it into the target repo's mise.toml (or merge under [tools]) and run mise install.

Global pin (one-time, any project):

mise use -g github:prettysmartdev/awman@0.11.0

Per-project pin (recommended for repos that run awman):

cp templates/0.11.0/mise.toml <your-repo>/mise.toml   # then: cd <your-repo> && mise install

The template's contents:

[tools]
"github:prettysmartdev/awman" = "0.11.0"

Verify:

mise which awman && awman --version

Fall back to the upstream installer (curl -s https://prettysmart.dev/install/awman.sh | sh) only when mise is unavailable (locked-down CI image, no GitHub release network access). State the reason explicitly when doing so. Building from source requires Rust 1.94+ and make (git clone https://github.com/prettysmartdev/awman.git && cd awman && make install). Do not use Homebrew, asdf, or mason — none are documented by upstream.

Migrating from amux

The rename is automatic for existing users:

• Config migrates automatically on first run. Change any AMUX_* environment variables to AWMAN_* and you are done.
• The binary is now awman; the installer offers to clean up old amux binaries.
• Config keys under headless.* are now under api.* (e.g. headless.workDirs → api.workDirs).
• The server command amux headless start is now awman api start.
• Per-repo config moved from aspec/.amux.json to GITROOT/.awman/config.json (see Config below).
• Markdown workflow files (.md) are no longer supported — use TOML or YAML.

First-Run Diagnostic

awman is pre-1.0 and ships frequently. Run these before trusting that docs match the installed binary:

awman --version
awman config show

awman config show prints the merged effective config (global + per-repo). Use it to verify runtime, default_agent, and overlay state rather than reading JSON files directly.

Command Tree

See templates/0.11.0/commands.md for the full v0.11.0 command surface with flags and examples.

GitHub Issue Integration (0.10.0)

--issue <ref> on new spec, exec workflow, and exec prompt fetches a GitHub issue and injects it. Reference forms: bare number (--issue 84, requires a GitHub origin remote), shorthand (--issue owner/repo#84), or full URL. Auth resolution: gh CLI → GITHUB_TOKEN → unauthenticated REST (public repos, 60 requests/hour). For exec workflow the issue populates the {{work_item_*}} template variables exactly as --work-item does; --issue and --work-item are mutually exclusive.

Dynamic Workflows (0.11.0)

awman exec workflow --dynamic --work-item <N> launches a leader agent that reads the work item, designs a workflow.toml, and executes it — no hand-authored workflow file. --dynamic auto-enforces --yolo, --worktree, and the context(workflow) overlay; passing them explicitly is a no-op, and --dynamic rejects a workflow path, --plan, or a missing --work-item.

Leader resolution (highest wins): --leader <agent::model> flag → dynamicWorkflows.defaultLeader config → --model on the project default agent → project default agent and model. The dynamicWorkflows config section constrains the plan: agentsToModels (approved agent→model map; empty falls back to Dockerfile discovery), maxConcurrentSteps (advisory, not runtime-enforced), and guidance (project instructions injected into the leader prompt, max 50 × 1,000 chars). An invalid generated workflow triggers a repair agent up to 3 times. See references/config.md for the key schema.

Parallel Execution (0.11.0)

Workflow steps with identical depends_on sets form a parallel group and run concurrently. Cap simultaneous containers with maxConcurrentAgents; precedence: --max-concurrent flag → AWMAN_MAX_CONCURRENT_AGENTS env → repo config → global config → unlimited. 1 disables parallelism; 0 is rejected. A failed step without abort_on_failure lets siblings continue; abort_on_failure = true kills all active peers. Stuck detection (30 s) and yolo countdowns (60 s) track per container. See references/config.md for the maxConcurrentAgents key schema and references/workflows.md for full parallel-group grammar and worked examples.

TUI: Ctrl-S rotates focus between parallel containers; Ctrl-G toggles a git sidebar (per-file +/- counts, ~2 s refresh, compact +X -Y in the status bar when closed); Ctrl-, opens the config dialog (Ctrl+N adds nested dynamicWorkflows entries).

Cleanup and Failure Logs (0.11.0)

awman clean [--dry-run] [--yes] removes stopped containers, dangling awman-labeled images, and completed-workflow data (repo .awman/workflows/ state, ~/.awman/context/workflows/ dirs). In-progress workflows and active containers are preserved. Failed step output (100 lines) lands in `/.awman/logs/{workflow-id}-{step-name}-{container-name}.log— created on demand, **never auto-cleaned** (not even byawman clean). Teardown on_failureremediation agents receive the failed command's output as a readable file; setupon_failureagents do not. Seereferences/workflows.md`.

Agents

Supported agents: claude, codex, opencode, maki, antigravity, copilot, crush, cline.

gemini is deprecated by Google upstream. Migrate to antigravity (awman chat --agent antigravity or awman config set agent antigravity). The gemini agent name remains accepted but logs a deprecation warning and has degraded system-prompt-injection support.

Each agent has a Dockerfile in .awman/Dockerfile.<agent> (seeded from upstream templates). Customize the Dockerfile to add tools or environment configuration for that agent. The project base image path is configurable via the per-repo dockerfile config key (default Dockerfile.dev) as of 0.10.0.

Selection precedence (highest wins):

1. Per-step agent: field in the workflow file
2. --agent <name> flag on the CLI invocation
3. agent key in per-repo .awman/config.json
4. default_agent key in ~/.awman/config.json (global default; factory default: "claude")

Worktrees

Opt-in via --worktree on awman chat / awman exec. All steps in a single workflow run share one worktree.

Worktrees are never auto-deleted. At session end, awman prompts: merge / discard / keep. On abort, the worktree is preserved for manual inspection. Monitor disk use when running repeated --yolo --worktree workflow runs.

Containers run --rm and auto-remove at session end. Only the Git repository is bind-mounted; /workspace inside the container is ephemeral beyond what lands in the Git tree.

Config Files

awman reads one config.json per scope:

Per-repo takes precedence on overlapping scalar keys. The overlays string array merges additively across all sources (global config, repo config, AWMAN_OVERLAYS, --overlay flags, workflow steps); other list fields replace. The repo .awman/ directory also holds per-agent Dockerfiles seeded by awman init. XDG base-directory environment variables are honored as of 0.10.0. Always use awman config show to see merged values rather than hand-editing the JSON.

See references/config.md for the full per-key schema (type, default, scope, merge behavior).

Overlays

Overlay specs grant agent containers access to host resources: dir(HOST:CONTAINER[:ro|rw]), ssh(), env(VAR), skill(*)/skill(NAME), and — new in 0.10.0 — context(global|repo|workflow[:ro]). Context overlays combine a persistent host directory (~/.awman/context/...) with automatic system-prompt injection, giving agents a durable shared workspace across sessions; they default to rw so agents accumulate knowledge — pass :ro to lock them. On host-path conflicts, :ro always overrides :rw. See references/config.md for the full overlay grammar.

env passthrough example

To make an agent use a local provider or custom endpoint, forward the relevant vars via env() overlays:

{
  "overlays": [
    "env(ANTHROPIC_BASE_URL)",
    "env(ANTHROPIC_API_KEY)"
  ]
}

Or one-off via CLI flag (repeatable, or comma-separated in a single flag):

awman chat --overlay "env(ANTHROPIC_BASE_URL)" --overlay "env(ANTHROPIC_API_KEY)"
# or
awman chat --overlay "env(ANTHROPIC_BASE_URL),env(ANTHROPIC_API_KEY)"

If ANTHROPIC_BASE_URL is not set on the host, awman silently omits it — not an error.

envPassthrough is removed in 0.10.0. The old envPassthrough array config key no longer works; awman config get envPassthrough returns a removal notice. Express env forwarding as env() overlay entries in the overlays array (config file, AWMAN_OVERLAYS, or --overlay flag) instead. See references/config.md for the migration table.

API Mode

awman api start runs a REST server on port 9876 (configurable via --port). It serves HTTPS with a self-signed certificate by default — pass --dangerously-skip-tls for plain HTTP in trusted local setups. It accepts bearer-token auth. Sessions are restricted to directories in api.workDirs (global config) or passed via --workdirs.

FIFO queue per session. Submitting a second command while one is in flight enqueues it — submission never blocks and returns immediately with a command_id. Poll GET /v1/commands/:id or stream /v1/commands/:id/logs/stream (Server-Sent Events) to track progress. A POST /v1/sessions with a workdir outside the allowlist returns HTTP 403.

Prefer awman remote over raw curl when driving the server from the CLI — it carries auth and the session header per the operator-tooling-first convention.

See references/api.md for the full endpoint table and curl examples.

Workflow Authoring

Workflows are TOML (.toml) or YAML (.yml/.yaml) files authored via awman new workflow [--interview] and executed via awman exec workflow <path>. Markdown (.md) workflows are no longer supported as of 0.9.1.

Step fields are lowercase only: name and prompt are required; depends_on, agent, model, and overlays are optional. Template variables available in prompts: {{work_item_number}} (zero-padded 4-digit), {{work_item}} (bare number), {{work_item_content}} (full file or fetched issue), {{work_item_section:[Name]}} (named section).

New in 0.10.0, workflows support setup and teardown phases with typed steps (clone_repo, checkout_create_branch, run_shell, commit_changes, push_branch, create_pull_request, …), including poll_ci (block until the branch's GitHub Actions run completes; interval_secs/max_retries) and per-step on_failure blocks that launch a remediation agent and retry the step up to max_attempts times.

See references/workflows.md for grammar in both formats and worked examples.

Known Sharp Edges (Pre-1.0)

• Not a tmux wrapper. awman ships its own TUI. The name is misleading.
• Markdown workflows dropped in 0.9.1. Only TOML and YAML are accepted; other extensions are rejected.
• API server is HTTPS by default. Local curl needs --dangerously-skip-tls (server side) or trusting the self-signed cert.
• Commands queue, not reject. A busy session enqueues new commands in FIFO order rather than returning 403; a closing session returns HTTP 409.
• runtime is global-only. No per-repo runtime selection.
• docker-sbx-experimental skips all overlays. dir(), skills, and context mounts are not honored; networking is proxy-only; sandboxes persist between sessions and lose port mappings on stop.
• --issue and --work-item are mutually exclusive. Bare --issue <N> requires a GitHub origin remote — use owner/repo#N or a URL otherwise.
• Context overlays default to rw. Use context(SCOPE:ro) to stop agents from modifying accumulated knowledge.
• envPassthrough is removed. The old config key returns a removal notice. Use env() overlay entries in the overlays array instead.
• gemini is deprecated. Use antigravity as the replacement (awman config set agent antigravity).
• --dynamic force-enables --yolo, --worktree, and context(workflow). There is no supervised dynamic mode.
• Unset maxConcurrentAgents means unlimited parallelism. 1 disables it; 0 is rejected.
• ~/.awman/logs/ grows unbounded. awman clean does not remove failure logs.
• Setup-step on_failure gets no automatic output capture. Only teardown steps hand the failure output to the remediation agent.
• Frequent release cadence. Re-run awman --version when output looks unexpected. Pin in mise to control when you upgrade.
• Lowercase keys only in workflow files. Uppercase variants are parse errors.

Anti-Fabrication

Run awman --version and awman config show before asserting that any documented behavior matches the installed binary. awman is pre-1.0 and minor bumps carry breaking changes. Every command form in this skill traces to upstream docs sourced from https://github.com/prettysmartdev/awman (accessed 2026-07-13). Mark any behavior not confirmed by that source as "requires verification against awman v0.11.0 source." Apply /core:anti-fabrication rules to all outputs produced with this skill active.
