Blueprint

Constraints

• Apply @rules/git/general.mdc — branch, commit, and PR conventions below come from it.
• Apply @rules/compound-engineering/general.mdc — the plan is durable memory the next agent reuses, not throwaway prose.
• Apply @rules/compound-engineering/general.mdc Assign the most relevant existing label when creating a tracker issue for any tracker issue this plan creates or hands off to @skills/create-issues-from-text/SKILL.md to create.
• Apply @rules/laravel/architecture.mdc when the project uses pekral/arch-app-services, so each step lands in the correct layer.
• Plan only. Do not implement, commit, or push any step.
• Output Markdown only. English only.
• Every step must be one pull request: independently reviewable and mergeable on its own.
• Break the objective into 3-12 steps. Fewer means it likely fits one PR; more means the objective is too broad and should be split first.
• Each step must be executable cold by @skills/resolve-issue/SKILL.md or a fresh agent with no prior context.
• Do not invent dependencies on tooling that may be absent. Degrade gracefully when GitHub CLI (gh) is missing.

Use when

• An objective clearly exceeds one pull request (a migration, a multi-layer feature, a cross-cutting refactor).
• Work will span multiple sessions or multiple agents and needs a sequenced, resumable plan.
• You need to know which parts can run in parallel and which must be sequential before starting.

Do not use for single-PR tasks (use @skills/analyze-problem/SKILL.md or @skills/resolve-issue/SKILL.md), for splitting an objective into tracker issues without a dependency graph (use @skills/create-issues-from-text/SKILL.md), or when the user wants one high-leverage suggestion (@skills/smartest-project-addition/SKILL.md / @skills/product-capability/SKILL.md).

Execution

Run the five phases in order. Do not register a plan that has not passed Review.

1. Research — Establish ground truth before planning.

• Read the actual code, layers, and conventions the objective will touch. Per @rules/compound-engineering/general.mdc, find the existing part of the system the work extends before inventing a new abstraction.
• Walk git log / git blame over the affected area to learn how it evolved and what was already tried or reverted.
• Detect the git baseline: confirm the repo, the default branch (master), and whether gh is available (gh auth status). Record the result; it drives the PR template in Output.
• For an unfamiliar pattern, library, or security-sensitive surface, consult current authoritative references and cite them.

1. Design — Decompose the objective into 3-12 one-PR steps.

• Each step is the smallest change that delivers reviewable value and can merge alone.
• Sequence steps so each builds on a merged predecessor; never assume an unmerged step's code.
• Map dependency edges: for every step, list which steps must merge before it. Steps with no shared files and no dependency edge between them may run in parallel.
• Name the layer each step lands in (Action, Service, Repository, etc.) when @rules/laravel/architecture.mdc applies.

1. Draft — Write the per-step plan (structure in Output).

• Give every step a self-contained context brief: enough background, file paths, and conventions for a fresh agent to execute it without reading the other steps.
• Write concrete, observable exit criteria per step (tests, behavior, verification commands).
• Add the parallelism summary: the dependency graph and which steps may run concurrently.

1. Review — Adversarially check the draft against the anti-patterns below before registering. Fix every hit; re-run until clean.

• A "step" that spans multiple PRs, or is too small to justify its own PR.
• A step whose context brief is not self-contained (assumes prior conversation or another step's unmerged work).
• Missing, unobservable, or untestable exit criteria.
• Hidden ordering: two steps marked parallel that touch the same files or share an unstated dependency.
• A new abstraction where an existing part of the system already fit (@rules/compound-engineering/general.mdc).
• Branch / commit / PR wording that violates @rules/git/general.mdc (wrong type, base branch, period, attribution).
• A plan that assumes gh exists when Research found it absent.

1. Register — Persist the approved plan as Markdown in the repo (e.g. docs/plans/<objective-slug>/): one README.md index plus one file per step, or a single plan file when small. State the path so the next agent picks it up.

Output

Register a plan index plus one entry per step.

Plan index (README.md): objective in one or two sentences; ordered step list; the parallelism summary; git baseline (default branch master, gh present yes/no).

Per step:

• Title — type(scope): short description, lowercase type/scope, no trailing period (@rules/git/general.mdc).
• Branch — feature branch off master (e.g. feat/<short-slug>).
• Context brief — self-contained background, file paths, and conventions; readable cold, with no reference to other steps' unmerged work.
• Tasks — concrete, ordered actions implementing this one PR.
• Dependencies — the step IDs that must merge first; none if it can start immediately.
• Exit criteria — observable, verifiable conditions that prove the step is done: tests to pass, behavior to confirm, and the exact verification commands to run.
• PR — title in English; body as Markdown linking the issue (Closes #N) when one exists. Open with gh when available; otherwise output the title and body for the human to open manually and say so.

Parallelism summary — the dependency graph (e.g. 1 -> 2 -> 4, 3 parallel to 2) and an explicit list of step sets that may run concurrently because they share no files and no dependency edge.

Done when

• The plan has 3-12 steps, each one mergeable pull request.
• Every step has a self-contained cold-start context brief, explicit dependencies, and observable exit criteria.
• The parallelism summary states what can run concurrently and what must be sequential, with no hidden shared-file conflicts.
• The Review pass found no remaining anti-patterns.
• Branch, commit, and PR templates follow @rules/git/general.mdc and degrade gracefully when gh is absent.
• The plan is registered as Markdown in the repo and its path is reported.
