Create structured plans for multi-step work, including software and non-software tasks. Use when asked to plan, break down implementation, plan from requirements, or deepen an existing plan; prefer ce-brainstorm for exploratory framing.

Create Technical Plan The current year is 2026. Outcome: a plan for carrying out and checking the agreed work while preserving its outcome and constraints. Resolve technical choices from evidence; leave adequate instructions unchanged. ce brainstorm defines WHAT , ce plan plans HOW , and ce work executes. A prior brainstorm is optional. An explicit invocation always produces a plan. Never classify a direct invocation as "not a planning task" and route out. It may select any output contract below, and the smallest valid plan is a few sentences in chat. Research, decide, and write the plan — never implement. Do not write production code, run tests, or learn from execution time results. Directional pseudo code and grammar sketches may communicate design; changing code to see what happens belongs in ce work . Mandatory Completion Contract A run is complete when its output contract's done condition is met. Every normal interactive branch that produces a plan artifact or checkpoint is incomplete until the user has been asked what to do next. A request that already authorizes the next action is that answer. For a Durable software implementation plan run that continues past the resume check, that means the Phase 5.4 menu has been presented and the selected action has actually fired. For Direct, the change stated and the handoff offered; for a Chat brief, the brief and its one line save or ce work offer in chat. Neither presents the Phase 5.4 menu. Non software plans and approach level plans end with the handoff their reference workflow defines. A run that only answers a question may end after the answer unless its reference requires a save or share step. Writing the file, checking confidence, and running or explicitly skipping ce doc review are intermediate milestones. In pipeline mode, the run is complete only when the plan, the confidence check, and the non interactive document review state have been returned to the caller, which decides what happens next. Interaction Method Ask one question at a time through the host's blocking question tool already in the current tool list. Match by capability; never probe a user facing tool to discover it. If none is listed or a real question call errors, render numbered choices in chat; never silently skip a required question. If no feature description was supplied, ask what to plan and wait. Output Contract Decide which output contract applies at the start of scoping (Phase 0.6), before choosing depth and before the scoping synthesis. It applies only when no resume route (Phase 0.1) fired and the source check (Phase 0.2) found no upstream artifact. Ground it with bounded inline reads of what the request names, without dispatching a subagent. Select one: Direct — the work can be stated, done, and verified in one pass with no decision the user would weigh. State the change in a few sentences and offer the handoff to ce work or the user; execution starts only with implementation authority, as references/output contracts.md defines. Chat brief — bounded work with at most one decision the user would weigh and no risk surface. Deliver it in chat and stop. Durable — everything else. Continue the workflow below. references/output contracts.md defines Direct and Chat brief; read it when either is selected. When the tier is still uncertain after those reads, take the heavier one. If a read surfaces a decision the user would weigh, a risk surface, or multi pass verification, move to the heavier tier before emitting anything. Durable regardless of size: a run with no synchronous user to act on chat this turn (pipeline, headless, goal or scheduler driven), a request whose wording asks for a plan, a plan file, or an output format, a request that continues an existing plan's item, and a risk surface — authentication, payments, migrations, external contracts. Workflow Phases run in order unless a reference routes out or short circuits. Read a phase's required reference in full when you enter that phase; a read made before that phase does not satisfy it, and a reference named for the final steps is read again at its step even when already in context. If a required reference cannot be read, stop before the action it governs and report the blocker and recovery path; never reconstruct the missing rules from memory. In pipeline mode, every required reference failure returns status: blocked , phase , blocker , and recovery path ; include artifact path and preserve the artifact when one exists. Report blocked even when an artifact exists. Phase 0: Output, Resume, and Scope 1. Output first. Read references/output mode.md before interpreting any phase. It defines token parsing, output and confirmation precedence, renderer selection, artifact location, and when a repository may be resolved. 2. Resume, deepen, approach, and domain. Read references/resume.md before acting. It defines resuming an existing plan, enriching a requirements only plan, deepening, approach level planning, and the software/non software split. Follow any terminal route it selects; otherwise continue. 3. Source and scope. Read references/intake.md before Phase 0.2 and follow it through Phase 0.7. It defines finding and preserving the upstream artifact, routing out to bootstrap work, blocking questions, depth, named resources, and the scoping synthesis; the Output Contract decision above happens inside it. Do not pass a decision point that has not resolved. Phases 1 4: Research and Compose 4. Read references/research.md before gathering context. It defines local and external research, consolidation, depth reclassification, flow analysis, and requested Bake offs. 5. Read references/structure.md before resolving questions or structuring the plan. It defines settled decision handling, stable U IDs, technical design, depth, and planning boundaries. 6. Compose from references/plan sections.md plus the format rendering reference selected by output mode.md . Phase 5: Review, Write, Deepen, and Hand Off 7. Read references/final review.md before the pre write review. It defines Phase 5.1 through 5.3.2: scoping synthesis, writing the file, unified plan metadata, confidence mode, and deepening. 8. Model elevation. Immediately before authoring, read references/reasoning elevation.md , resolve the choice at this boundary, and follow it. Do not author until activation resolution has completed and any selected dispatch or transparent fallback has settled. 9. In pipeline mode, evidence that invalidates a decision settled earlier in the session stops the write. Return the exact token settled decision invalidated , the decision, and the reason; do not resolve it silently. 10. Write the plan before presenting options, then complete the confidence path final review.md defines. STOP. Read references/plan handoff.md immediately before Phase 5.3.8 and 5.4 (document review and the handoff menu). Document review is mandatory for a Durable plan and the default is non interactive ( mode:non interactive ). In interactive software runs, ask exactly: "Plan ready at <absolute path to plan . What would you like to do next?" Present its menu and wait. If the selection arrives after a user turn, reload references/plan handoff.md before acting. Rendering the menu, receiving a selection, or announcing a route is not completion; execute the selected action.
