feat(v2): ak onboard writes the config a repository needs in one call

[thewrz]

This was written agentically; verify its assertions:

Why

Joining a repository to ak today means hand-writing .agent/config.env (that is what ak plan's refusal asks for), or running the legacy onboard-repo skill: a 10 KB activation-gated procedure with nine steps and ~2,000 lines of helpers, most of its prose about what not to do, all of it read into the root's context before a single key is written. The v2 spec names onboard as "ak onboard, then commit the config it writes" and nothing shipped it yet.

What

One ak onboard [--project N --owner O] command plus a 21-line onboard skill, in the v2 shape.

• Writes only what the repository already says. Slug and base branch from git, the linked project board and its Status options from one GraphQL read, and setup/test commands from marker files: the lockfile chooses the package manager, a Makefile test: target wins, and a directory with its own toolchain becomes an AGENT_CMD_<DIR> suite with AGENT_RUNDIR_<DIR>, which ak verify already runs per area. A directory's install joins AGENT_CMD_SETUP only when a suite runs there.
• Keeps what is there. Existing keys are never overwritten, so a re-run is byte-identical and a legacy config gains only the keys it lacks. An untracked .agent/ is excluded through info/exclude, like .ak/.
• Prints at most 20 lines, ends with the proof. Each key written, a board= line, and next=ak setup && ak verify --full (or verify alone). Two linked boards print board=choose with the exact command that picks one; no board, no toolchain, and a failed board read are notes with their fix, not refusals.
• The skill is five "go" steps, no gates, no hooks, no activation: run ak onboard, settle board=choose or commands=none with one more call, run the next= command, report.

Turns and tokens removed: the ~30 KB the legacy path reads into the root (skill, two reference files, helper --help output) drops to the 1 KB SKILL.md; nine steps with a user hand-off per declared command become three calls.

Testing

• tests/v2/test-onboard.sh: 41 assertions covering a Node repo with one linked board, idempotent re-run, bad flag, two boards then --project, missing canonical column, no board and no toolchain, failed board read, a monorepo (Makefile whole check, uv/pnpm/go suites, composed setup, a non-suite package.json ignored), and the git exclude
• tests/v2/run.sh exit 0 (budget, ShellCheck 0.11.0 at style level, all 16 suites)
• tests/run-tests.sh --gates-only ALL GREEN
• Live smoke on a throwaway clone of this repository: one GraphQL read found board 10 with Backlog,Ready,In progress,In review,Done; the legacy config kept 5 keys and gained none it should not
• CI green on every push (gates, four suite shards, CodeQL)
• Two blind Codex adversarial reviews via ak review: gpt-5.6-sol xhigh (8 findings: 5 fixed, 3 declined with reasons) and gpt-6-astra xhigh (5 findings, all fixed, including a live-verified GraphQL fragment the stub could not catch); the receipt comment carries the ledger
• Field run: /onboard on a fresh field clone, then ak plan picks up the written board

Summary by CodeRabbit

• New Features
  • Added ak onboard to help set up repository configuration by detecting the base branch, project board, and available setup and test commands.
  • Existing configuration values are preserved. Onboarding reports missing information and issues that need attention, then provides a next step.
• Documentation
  • Added guidance for running onboarding, resolving incomplete setup details, and verifying the suggested command.

📝 Walkthrough

Walkthrough

ak onboard now derives repository details, discovers linked or specified GitHub Projects boards, and detects setup and test commands from tracked toolchain markers. It appends missing configuration values, reports notes and a verification command, and includes an operator workflow and integration tests.

Changes

Repository onboarding

Layer / File(s)	Summary
Command entry and configuration v2/bin/ak, v2/lib/onboard.sh, v2/skills/onboard/SKILL.md, tests/v2/test-onboard.sh	The root usage lists onboard. The command validates its arguments, collects repository details, preserves existing configuration keys, handles .agent/ exclusion and symlink cases, and reports results. The skill describes how to resolve its prompts and run verification.
Project board discovery and selection v2/lib/onboard.sh, tests/v2/test-onboard.sh	The command queries linked or specified projects, selects a board when possible, and reports lookup outcomes and missing Status options. Tests cover existing declarations, selection, and API failures.
Toolchain and suite detection v2/lib/onboard.sh, tests/v2/test-onboard.sh	The command detects setup and test commands from marker files and discovers per-directory suites. Tests cover command precedence, monorepo suites, and existing configuration.

Onboarding rejects the supported --project N form. Operators can supply --owner O as a workaround, but the command should accept the documented form before merging.

Full details: Linked Issues check

Explanation

Issue #997 requests output of at most 20 lines and each key written. v2/lib/onboard.sh limits displayed keys to 12 or 14, then replaces remaining keys with a (+N more...) line. It also prints an uncapped list of board choices and suite-skip notes, so output can exceed 20 lines. The skill's commands=none step asks the operator to find and append AGENT_CMD_TEST manually; it does not provide the one-more-call resolution stated in the issue. The command, configuration discovery, preservation behavior, and five-step skill otherwise address the requested onboarding work.

• Reviewer: gpt-6-astra (review=done)
• CI: green (checks=8 failing=)
• Findings:
  • P1 | Appending corrupts configs without a trailing newline | fixed 36a24b9
  • P1 | Normalized suite-name collisions emit duplicate keys | fixed 36a24b9
  • P1 | Root setup suppresses required suite installs | fixed 36a24b9
  • P2 | Supported suite markers are omitted from discovery | declined: a bare requirements.txt or a tests/run-tests.sh below the root marks a scripts directory as often as a project; the root keeps both markers, and a suite the operator wants is one AGENT_CMD_ line
  • P2 | Linked-project discovery silently truncates after 20 boards | declined: a repository linked to more than 20 open boards is not a case onboard needs to detect; --project N --owner O names a board explicitly either way
  • P2 | Multi-board selection assumes every board has the first board's owner | fixed 36a24b9
  • P2 | Status existence checks are incorrectly case-insensitive | declined: ak board and ak plan both match Status options with ascii_downcase, so a lower-case column is one they can move to
  • P2 | Added ignore rule hides nested agent directories too | fixed 36a24b9
  • P1 | Explicit board selection always fails (RepositoryOwner has no projectV2) | fixed 608e97f
  • P2 | Existing suite commands acquire an incompatible working directory | fixed 608e97f
  • P2 | Partial board configuration can target the wrong project | fixed 608e97f
  • P2 | Failed branch discovery permanently records a guessed base | fixed 608e97f
  • P2 | Appending the exclusion can corrupt the previous rule | fixed 608e97f
