Autonomous Dev Team Dispatcher

Scan GitHub issues and dispatch dev/review tasks. One cron tick is one invocation of dispatcher-tick.sh (single-project) or dispatcher-multi-tick.sh (multi-project). The full state machine, per-step semantics, and invariants live at docs/pipeline/ in the source repo — that's the spec; this file is the agent's invocation contract.

Prerequisites

• gh and jq on PATH.
• For the local backend: $PROJECT_DIR set, pointing at the project root. Per-project autonomous.conf (see scripts/autonomous.conf.example).
• For multi-project / remote backends: dispatcher.conf declaring PROJECTS=() (see scripts/dispatcher.conf.example).
• autonomous-dev.sh and autonomous-review.sh need the execute bit (mode 100755) — restored upstream and self-healed by dispatcher-tick.sh on every tick (#97).

Security note: This dispatcher processes GitHub issue content as input. In public repositories, issue content is untrusted — anyone can create issues. Ensure the autonomous label can only be applied by trusted maintainers (use GitHub branch rulesets or organizational policies). The dispatcher only reads labels/comments and spawns local processes via the helper script — it does NOT modify source code or push to branches.

What to do

When the cron fires (default: every 5 min), run one of:

Single-project deployment (one repo per dispatcher):

bash "$PROJECT_DIR/scripts/dispatcher-tick.sh"

Multi-project deployment (one cron, many repos — closes #62):

DISPATCHER_CONF="$HOME/.autonomous/dispatcher.conf" \
  bash "$PROJECT_DIR/scripts/dispatcher-multi-tick.sh"

The multi-tick wrapper iterates PROJECTS=() from dispatcher.conf and runs one dispatcher-tick.sh per project. Per-project failures are logged to stderr but do not stall other projects. See scripts/dispatcher.conf.example for the schema.

Each PROJECTS[] entry is one of two shapes:

• Local project (file path): a path to a per-project autonomous.conf on this dispatcher box. The dispatcher and the project source live on the same machine. The wrapper sources the conf via the AUTONOMOUS_CONF priority-1 path (PR-4 / [INV-14]).
• Remote project (inline metadata block): used when the project source lives on a remote dev box reached via AWS SSM. The dispatcher box does NOT have the project's autonomous.conf — everything the dispatcher needs to scan issues + dispatch is declared inline in dispatcher.conf. EXECUTION_BACKEND=remote-aws-ssm and SSM_INSTANCE_ID route the actual dispatch-local.sh invocation to the remote box via aws ssm send-command. (#62)

Either form runs the same 5-step tick:

1. Concurrency gate — abort if count(in-progress + reviewing) >= MAX_CONCURRENT.
2. scan-new — find autonomous-only issues, check dependencies, dispatch dev-new.
3. scan-pending-review — find pending-review issues, dispatch review.
4. scan-pending-dev — find pending-dev issues, retry-counter check, dispatch dev-resume (or mark stalled if exhausted).
5. stale detection — for in-progress / reviewing issues, probe wrapper PID, branch on alive/dead and on PR/CI/idle gates.

The logic is in scripts/dispatcher-tick.sh and the helpers in scripts/lib-dispatch.sh. For the spec each step is implementing, see docs/pipeline/dispatcher-flow.md in the source repo.

GitHub Authentication — App token, not user token

All gh calls inside the dispatcher use a GitHub App token, not the default user token. The wrappers (autonomous-dev.sh, autonomous-review.sh) handle their own auth via lib-auth.sh; the dispatcher tick handles its own.

When GH_AUTH_MODE=app, dispatcher-tick.sh automatically calls gh-app-token.sh::get_gh_app_token after upfront validation and exports GH_TOKEN before any gh call (#91). Required vars in the project's autonomous.conf or the inline metadata block:

GH_AUTH_MODE=app
DISPATCHER_APP_ID=<numeric app id>
DISPATCHER_APP_PEM=<absolute path to PEM>

If any of those are missing, or if token generation fails, the tick exits 1 with a FATAL message — there is no silent fallback to user auth.

The token is valid for 1 hour and scoped to the target repo only. dispatcher-tick.sh typically completes in well under a minute, so a single token covers the whole tick. When GH_AUTH_MODE=token (default) or unset, the dispatcher uses whatever GH_TOKEN / gh auth login token the caller provides.

Dispatch Helpers

dispatcher-tick.sh calls a dispatch() helper for each task type, which routes to the configured execution backend. Do NOT spawn agent processes any other way. Each backend handles nohup, input validation, log-file mode 0600, and stale-wrapper kill (INV-09).

Backends today:

EXECUTION_BACKEND	Driver	When to use
local (default, also when unset)	scripts/dispatch-local.sh	Wrapper runs on the same box as the dispatcher.
remote-aws-ssm	scripts/dispatch-remote-aws-ssm.sh	Wrapper runs on a remote dev EC2 reached via AWS Systems Manager. The dispatcher sends aws ssm send-command to invoke dispatch-local.sh on the remote box.

Per-task command shapes (passed through both backends identically):

Type	Command
New dev task	dispatch dev-new ISSUE_NUM
Review task	dispatch review ISSUE_NUM
Resume dev task	dispatch dev-resume ISSUE_NUM SESSION_ID

What the dispatcher MUST NOT do

The dispatcher is a label-and-spawn coordinator, not a code-changer:

• MUST NOT commit or push to the target repository.
• MUST NOT modify source files in $PROJECT_DIR.
• MUST ONLY read issue labels/comments via the GitHub API, update labels via the GitHub API, and dispatch wrapper processes via the configured backend (dispatch-local.sh or dispatch-remote-aws-ssm.sh).

Any code changes happen via the wrapper-spawned dev / review agents.

Environment Variables

Loaded from scripts/autonomous.conf (sourced by dispatcher-tick.sh before lib-dispatch.sh):

• REPO: GitHub repo in owner/repo format (e.g., myorg/myproject)
• REPO_OWNER, REPO_NAME: split form of REPO (used for App token scoping)
• PROJECT_ID: project identifier for log/PID files (default: project)
• PROJECT_DIR: absolute path to the project root on the local machine
• MAX_CONCURRENT: max parallel tasks (default: 5)
• MAX_RETRIES: max dev retry attempts before marking issue as stalled (default: 3)
• DISPATCHER_APP_ID: GitHub App ID for the dispatcher bot
• DISPATCHER_APP_PEM: path to the GitHub App private key PEM file

Label Definitions

Label	Color	Description
autonomous	#0E8A16	Issue should be processed by autonomous pipeline
in-progress	#FBCA04	Agent is actively developing
pending-review	#1D76DB	Development complete, awaiting review
reviewing	#5319E7	Agent is actively reviewing
pending-dev	#E99695	Review failed, needs more development
approved	#0E8A16	Review passed. PR merged (or awaiting manual merge if no-auto-close present)
no-auto-close	#d4c5f9	Used with autonomous — skip auto-merge after review passes, requires manual approval
stalled	#B60205	Issue exceeded max retry attempts; requires manual investigation

Model Strategy

Task	Model	Rationale
Development (autonomous-dev.sh)	Opus (default)	Complex coding, architecture decisions
Review (autonomous-review.sh)	Sonnet (--model sonnet)	Checklist verification, avoids Opus quota contention
