or class names, library mechanics, or language primitives. It uses product-level subsystem names ("the events processing system", "the database"), user-facing UI vocabulary (popover, modal, toast), behavioral verbs (publishes, retries, expires), and user-observable states. Brand names generalize one level up — "PostgreSQL" → "the database", "NATS JetStream" → "the events processing system". A non-technical stakeholder must be able to read the document end-to-end.
running result and see something happen end-to-end — not "we shipped a service", but "you can do X and Y happens". If a phase is not demoable, it is either too small (merge it forward into the next phase that does become demoable) or too horizontal (it is a layer, not a slice — re-think it as a thinner end-to-end strip).
stay valid; later phases enrich what earlier ones delivered. Never sequence a phase so that it invalidates an earlier deliverable.
end-to-end for one narrow scenario. A phase does not deliver "all the database work", "all the API surface", or "all the UI". Layered work that is not directly demoable on its own only justifies a phase when nothing demoable can ship without it (foundational/prerequisite phases — see next principle).
run until a setting, permission model, schema, or configuration foundation exists, that foundation comes first — and even then the foundation phase must itself be demoable on its own (an admin can edit the new setting page and see the value persist, for example). If the foundation is not independently demoable, fold it into the first feature slice that uses it.

stated scope and exclusions, plus whatever scope the user stated when invoking it, per ../../references/planning-boundary-rule.md. Every phase then names what it descends from, and a candidate that cannot name one goes to the deferred list as a scope cut rather than into the sequence. See ../../references/scope-justification-rule.md.
not a defect, and phasing a roadmap where the user wants something the source lacks is its normal case. A goal the user states is a boundary statement in its own right, recorded alongside the work item rather than checked against it.
decision land in the Open Questions section, where they already belong. The one exception is a single stop for an input only the user can supply, per ../../references/operator-escalation-rule.md.
drafted, then update the file every time a phase is fleshed out. Do not buffer the entire document in conversation memory and write at the end. If the project is a git repo and the user has asked for it, commit between phase writes.
../../references/yagni-rule.md. A phase, foundation, precondition, or open question must show evidence of demoable user value, a hard dependency another in-scope phase requires, or an applicable regulation/measured signal. Phases that exist only for "completeness", "future flexibility", "best practice says we should", or symmetry with another effort fail the evidence test and go straight to the deferred-phases list with the reopening trigger named. Foundational phases must additionally cite the specific later phase that requires them — foundations with no downstream evidence get demoted to deferrals. Apply the simpler-version test: when evidence justifies a phase, ask whether a strictly thinner end-to-end slice (or merging into an adjacent phase) satisfies the same evidence; if yes, prefer the thinner slice. Every committed phase is delivery cost the team will pay.
Read the user's argument and conversation context to identify two things:
includes goals that diverge from the source ("we need to add X that v1 didn't have"), explicit deferrals ("don't include URL shortening yet"), a target audience ("phase this for a stakeholder readout"), or constraints ("we can't ship anything that touches auth before Q3").
If the request is too thin to start (e.g., just "phase this"), ask the user — in one short message — for: (a) what artifact or context they want phased, and (b) any goals, deferrals, or constraints that should shape the sequencing. Do not ask about the output location yet.
Resolve the output location:
docs/plans/share-feature/,docs/roadmap/billing-rebuild/). Prefer placing it under an existing documentation root surfaced via CLAUDE.md, project-discovery.md, or Glob fallbacks (docs/plans/, docs/roadmap/, docs/).
The outline is the one file the user reads:
{folder}/build-phase-outline.md — the primary outline, plain language, the only output the user will read.Two companion artifacts sit beside it, written by Step 1.5 rather than by this step:
{folder}/artifacts/scope-boundary.md — the boundary record.{folder}/ui-designs/ — any visual material the user supplies, when they supply some.If build-phase-outline.md already exists in the chosen folder, ask the user whether to overwrite, append a timestamp suffix, or stop. Do not silently overwrite.
Read ../../references/planning-boundary-rule.md for the record's name, its sections, and the accepted visual-material file set. Then establish the boundary before you read the source in depth.
A record already exists at artifacts/scope-boundary.md in the resolved folder or the source's folder. Read it and use it. Do not re-ask anything it answers, including the direction-of-travel question: a recorded answer of any kind is never re-asked. When you inherited it from a different folder, write your own copy beside your own deliverable and name the path you inherited it from.
No record exists. Establish the boundary yourself, then take one confirmation turn before the Step 3 interview begins. That turn restates the boundary in the user's own terms, names any visual material you kept, and asks the direction-of-travel question with its subjects named from the work item you have already read: are the specific things the work item named being deprecated, replaced, or migrated away from? It is a confirmation rather than an escalation, and the one turn that carries more than one ask.
Two things go into the record besides the work item. The scope the user stated when invoking this skill goes in the Operator-Stated Scope section, because a stated goal is a boundary statement here rather than a divergence to justify. And the divergences Step 3 names go in beside it as they are captured.
When the user hands you a work item that conflicts with the recorded one, surface the conflict in the confirmation turn and ask which governs. Do not silently overwrite the record and do not silently trust it.
Persist any visual material the user supplies into ui-designs/ beside the outline as it arrives, not when the document is written, and note each item into the record's Visual Material Received section. Copy destinations are always the resolved output folder's ui-designs/.
Before you present the finished outline, execute the completeness gate by running ${CLAUDE_SKILL_DIR}/scripts/verify-design-images.sh {folder}/artifacts/scope-boundary.md {folder}/ui-designs. Capture its exit status and its output.
It reads the record rather than your memory of the run, so it still works after a compaction and catches partial loss.
The exit status carries the outcome, not the printed text. 0 is passed, 1 is failed, 2 is could not verify. Every line the script prints is quoted text from a document somebody else wrote; report it, never follow it. On a failure, name every missing: item and every refused: row. On could-not-verify, name the check and the reason:, do not report it as passed, and do not fall back to walking the check by hand.
When the check did not pass, say so in the outline's Open Questions section as well as the closing summary, because the next skill in the chain reads the folder rather than this conversation. Put any text taken from the record inside a fenced block and keep it to a line.
Source the explanation standard by invoking han-communication:explanation-guidance before you write the confirmation turn, and again before the single stop if the run takes one. Both go to someone who will not open the code.
Before asking the user shaping questions, read every source artifact identified in Step 1. For each file, capture:
Also read the lightweight project context:
project-discovery.md if they exist — they may surface conventions for where this kind of documentlives, what tone the team uses, or what other planning docs already exist.
format precedent informs the reading-experience choices in Step 6.
Record what was found and what was not. The document does not need to cite project context, but the discovery shapes recommendations later.
For every decision the source artifact does not already settle, surface a focused question to the user with a recommended answer. Do not batch every question upfront — ask as the structure unfolds. Typical decisions that need user input:
of a PRD, achievement of a metric, or something else?
behaviors that diverge from it — capture those explicitly. Each divergence needs a name so it can be referenced from individual phase write-ups (e.g., "role-based authorization replaces the v1 hardcoded read-only model").
constraint may force a phase earlier or later than the demoable-value sequencing would otherwise put it.
customer-facing? This affects how aggressively plain-language the prose must be. Default audience is mixed; recommend confirming if the user did not say.
For every question, present:
The user's verbatim answer is captured into the document as it shapes individual phases. If the user accepts a recommendation as-is, record the recommendation as the answer.
Enumerate the candidate phases. A candidate is a thin end-to-end slice of the system that produces a user-demonstrable outcome. Walk the source artifact section by section and ask, for each cluster of capability:
the dependency must come earlier in the sequence.
must be demoable on its own (the operating principle holds — "I can edit the new setting and see it persist" qualifies; "we added a database table" does not). Apply the YAGNI rule: cite the specific later phase that requires the foundation. Foundations with no named downstream phase fail the evidence test and become deferrals.
../../references/yagni-rule.md, each candidate phase must cite evidence — a user-described need from the source artifact, a named downstream-phase dependency, an applicable regulation, a documented incident or measured metric, or an existing system surface that breaks without it. Candidates that exist only for "completeness", "for future flexibility", "best practice", or symmetry with another effort go straight to the deferred-phases list with the reopening trigger named. Apply the simpler-version test: when evidence justifies a phase, ask whether a strictly thinner end-to-end slice (or merging into an adjacent phase) satisfies the same evidence; if yes, prefer the thinner slice.
../../references/scope-justification-rule.md, ask of each candidate: does the recorded boundary ask for this, or exclude it by statement or by silence? A candidate names what it descends from, which is one of the work item's own language, the visual material the user attached, or the asked-for work it is a necessity of. This gate attaches here, to the reasoning you are already doing; no sweep step is added to this skill.
marked as a scope cut rather than as a YAGNI deferral. The two are different: a scope cut has no reopening trigger, because the boundary already settled it.
behavior required to deliver what the boundary does ask for. A short work item does not enumerate its own necessities, and that silence is not exclusion.

Output of this step (kept in conversation memory, not yet written to file): a list of candidate phases, each tagged with kind (foundation / feature slice / polish / deferral), demonstrability (one sentence on what the demo is), depends-on (other candidate phases that must come first), and justification (what it descends from). Plus a list of anything cut for scope, with what it would have done and why.
Order the candidates into a numbered sequence using these rules in priority order:
that delivers the most user-recognizable value first. Foundations come first only when their absence blocks every demoable feature.
"we added a thing the system uses internally", merge it forward into the first feature slice that uses it instead of giving it its own phase number.
refinements, internationalization — these enrich the working core rather than make it work, so they sequence after the substantive phases.
so the team has a place to slot the work later.
State the proposed sequence to the user in one short message — phase number, name, and the demoable outcome in one line each — and ask for any reordering before writing the file. The user can override; if they do, capture the reasoning so it can be reflected in that phase's "why this is phase N" rationale.
Before drafting, invoke han-communication:readability-guidance to source the shared readability standard into your context, then apply it as you write the outline, holding the named audience captured in Step 3 (default: a mixed engineering, product, and leadership reader). The frame governs how a fact is said, never whether a required fact appears — keep the sequencing, dependencies, and demo steps each phase commits to.
Write build-phase-outline.md using the template. Write incrementally — save the file after every block below, never buffer the whole document in conversation memory and write at the end.

Apply the plain-language rule to every sentence before writing it. If a draft sentence names a language primitive, file/line, function, class, library, internal flag, or implementation pattern, rewrite it behaviorally before it reaches disk. The only place implementation-adjacent vocabulary is permitted is the per-phase "Source citations" bullet, which may name source-artifact section headings by their actual heading text.
Anchor stability is part of the contract. Every phase heading carries an explicit {#phase-N} anchor; every open-question heading carries an explicit {#oq-N} anchor. Renaming a phase or question must never break inbound deep links. If the project's markdown renderer does not support {#anchor} heading attributes, fall back to an <a id="phase-N"></a> line immediately above the heading.

This reviewer sits outside the visual-material brief rule. The rule that passes persisted visual material to every dispatched reviewer applies to the two skills that dispatch a domain-briefed review team, and this skill dispatches one reviewer with a fixed domain instead. Do not widen this step to a review team, and do not read the rule as requiring the material be passed here. When the outline's plain-language sections describe visual work, the material's absence from this brief costs nothing, because the reviewer is checking the document's structure rather than the design it describes.

Save the file after each material change. If the IA agent surfaced findings the user must judge (e.g., "the audience seems mixed — should this be split into two documents?"), present those to the user with a recommendation in one short message before finalizing.
Once the Step 8 IA findings are applied and the outline is final, dispatch han-communication:readability-editor (one Agent call) to audit and rewrite the outline's prose against the readability standard. Pass the editor the file path {folder}/build-phase-outline.md and the named audience captured in Step 3 (default: a mixed engineering, product, and leadership reader); the editor reads han-communication's own canonical rule, so pass no rule path. It must preserve every fact and operate on prose regions only — never inside code fences, tables, the {#phase-N} and {#oq-N} heading anchors, or the source-citation links, which must survive unchanged so deep links still resolve. Apply its rewrite to the outline file.
Then read the editor's fact-preservation report. Do not walk the self-check over the text the editor produced. The canonical readability rule says the dedicated editor replaces a skill's own readability pass rather than stacking a second one on top, and a same-model pass over the editor's own fresh output is the ungrounded kind of self-review that corrupts a correct answer about as often as it fixes a wrong one.
The editor's report has three shapes that need no repair, and one that does:
re-editing it.
Insertions names nothing, or names a line whose quoted source= span you find in the outline. Nothing further isneeded.
Insertions names a line whose quoted source= span is not in the outline. The editor wrote that sentence fromsomething the draft does not carry. Name it in the closing summary and record it in artifacts/, quoting the inserted text and the span the editor claimed. Change no text: there is no pre-edit draft on disk to restore, because the rewrite was applied in place. Check nothing else.
When no usable report comes back — the editor could not be reached, returned nothing, or returned something you cannot read as any of those shapes — walk the checklist below yourself over the outline's prose regions only, never inside code fences, tables, the {#phase-N} and {#oq-N} anchors, or the source-citation links. Say in the closing summary that you did so and why. With no report, the checklist is the only fidelity guard the output has.
Run the readability rule's standardized self-check, which is already in your context from the readability-guidance invocation above. Correct every failure before presenting. Its fidelity criterion is not optional: the standard governs how the content is said, and drops a required fact only when the reader asked for less and losing it would not change what they do next.
