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. EXECUTIONBACKEND=remote-aws-ssm and SSMINSTANCE_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](scripts/dispatcher-tick.sh) and the helpers in [scripts/lib-dispatch.sh](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 GHAUTHMODE=app, dispatcher-tick.sh automatically calls gh-app-token.sh::getghapptoken after upfront validation and exports GHTOKEN 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 GHAUTHMODE=token (default) or unset, the dispatcher uses whatever token the caller provides through the code-host's standard channel — on GitHub, GHTOKEN or a gh auth login session; on GitLab (CODEHOST=gitlab), GITLABTOKEN or a glab auth login session. The chp/itp_ provider seams route through whichever is present.

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:

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

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)
• REPOOWNER, REPONAME: 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)
• DISPATCHERAPPID: GitHub App ID for the dispatcher bot
• DISPATCHERAPPPEM: path to the GitHub App private key PEM file
