| description | Shape an EPIC from human seeds, then derive its clarity-gated PLAN. Specifications-first, Shape-Up style — the EPIC is the work shape (appetite, problem, solution outline, key decisions, rabbit-holes, no-gos) and IS the OpenSpec proposal; the PLAN is the derived executable breakdown (design + tasks) scored by the clarity gate (≥9/10). Drives seed intake and a myriad of clarifying questions, makes no silent assumptions. Trigger on "write/refine an EPIC", "shape this work", "plan this epic", "derive the plan", "turn these seed notes into an epic". For the living-spec lifecycle (archive, grooming, memory) use spec-stewardship; for the doc-first build loop use external stream-coding. |

EPIC Planning
Overview
Specifications-first. Architecture and human intent are turned into shaped EPICs, each of
which derives a gated PLAN. In the Meaningfy spine the artifacts are OpenSpec-native (see the
spine): the EPIC ≡ proposal.md (the Shape-Up work shape) and the
PLAN ≡ design.md + tasks.md (the pair the clarity gate scores). One artifact per concept —
never a parallel EPIC.md/PLAN.md file. Ask before assuming; never ship a spec with hidden
assumptions (Human Sovereignty).
This skill authors. The living-spec lifecycle after authoring — archive, grooming specs/,
regenerating the orientation index — belongs to spec-stewardship.
Procedure (maps to the /opsx build-tier flow — see spine/workflows.md)
- Seed intake (
/opsx:explore). Read every human seed and supporting input — seed notes,
architecture/ADRs, sample/test data, free notes, and for brownfield an existing-codebase analysis
(optionally via GitNexus). Enumerate what you read. Details: references/seed-intake.md.
- Elicit (
/opsx:explore + superpowers:brainstorming). Drive a myriad of clarifying
questions, one concern at a time, to surface and decide every ambiguity, conflict, and
assumption before writing the EPIC. After each round, summarise what you understood and
confirm. Make no silent assumptions. Include a test-scenario interview: help the human enumerate
what the EPIC must prove — key assertions, scenarios, edge cases — so the design phase can author
.feature coverage (handed to bdd-gherkin; the PLAN's design half
references that coverage and clarity-gate scores it). Step definitions stay in implement.
- Archive the seeds. Write the captured seeds and the Q&A record to
changes/<id>/inputs/,
marked secondary and never deleted or groomed — the authored EPIC supersedes them but does
not replace them (the EPIC is the primary, shaped truth).
- Shape the EPIC (
/opsx:propose → proposal.md). Use the spine template
(openspec/schemas/meaningfy/templates/proposal.md):
appetite, why, solution outline, key decisions (each with a citeable DEC- id), rabbit-holes,
no-gos (mandatory). Cite the EPIC's golden-thread parents (the requirement/architecture it
derives from — see spine/golden-thread.md). Keep it at shaping
altitude — leave implementation room.
- EPIC readiness check (lightweight). Before deriving the PLAN, run the lightweight variant
of
clarity-gate over the EPIC — a quick readiness pass that catches
bet-level ambiguity (vague problem, missing no-gos, undecided key decisions). This is not the
full ≥9/10 gate (the Shape-Up bet stays deliberately looser); it just stops a vague EPIC producing
a vague PLAN.
- Derive the PLAN (
design.md + tasks.md). From the shaped EPIC, produce the design half
(algorithm, concrete examples, anti-patterns, error matrix, decisions) and the tasks half (ordered
breakdown with layers/dependencies/acceptance, roadmap). Each PLAN cites its parent EPIC id
(golden thread).
- Gate the PLAN (full
clarity-gate, ≥9/10). Score the design.md+tasks.md pair. Block
progression to BDD/implementation until it passes. Below 9: list the specific gaps and revise
the PLAN — never patch code to dodge a gap (Rule of Divergence).
When the bet itself is wrong (freeze vs re-shape)
The EPIC freezes once shaped. But elicitation or implementation can reveal two different kinds
of wrongness — handle them differently:
- PLAN-level wrongness (the approach/breakdown is off, the bet still holds) → revise the PLAN.
Normal divergence.
- EPIC-level wrongness (the bet itself is invalid) → re-shape the EPIC as a deliberate,
logged event — record why in the EPIC's decisions and the change inputs, not a silent edit. A
re-shape is a visible decision with an audit trail, which keeps the freeze meaningful.
What you do NOT do
- Write implementation code, Gherkin step definitions, or commit changes.
- Run the living-spec lifecycle (archive/groom/memory) — that is
spec-stewardship.
- Make architectural decisions unilaterally — propose options with trade-offs; the developer decides.
Boundary & Related Skills
Owns: the authoring practice — seed intake, elicitation, EPIC shaping (= proposal.md), the
lightweight EPIC readiness check, and PLAN derivation (= design.md + tasks.md).
Delegates: PLAN scoring → clarity-gate; the living-spec lifecycle
(archive, grooming, memory-index regen) → spec-stewardship;
Gherkin → bdd-gherkin; code → cosmic-python;
the doc-first build loop → external stream-coding. For the texture of the EPIC/PLAN narrative
prose (the proposal "why" and "solution outline" are Explanation-quadrant), the writing family applies:
technical-writing and
explanatory-writing — referenced, not restated.
