Comet native skill

Comet Native

Native saves complete requirements, progress, and acceptance results in the project. The Agent works only on the phase specified by Runtime. After each action, read the latest continuation and follow it until the task is complete, a user decision is needed, or an external dependency blocks progress.

Required rules

• Continue confirmed implementation, document repairs, evidence reuse, and recovery. Pause for new decisions, authorization, or external information. Use current continuation commands, templates, and packages; correct inputs within the same task.
• Treat .comet/config.yaml, the current change, comet-state.yaml, and formal artifacts on disk as authoritative; chat memory is supplementary. Among formal workflow files, the Agent edits only the brief, complete target Specs, association delta.yaml, and children.yaml. Runtime owns state, check results, reports, locks, and transactions.
• Advance through the public comet native CLI on PATH; do not ask the user to run commands manually. If the command is unavailable, report an incomplete installation and stop. Consult comet native <command> --help for arguments.
• Create changes with the CLI; use returned paths and follow denial commands or targets before retrying. Custom and non-Comet writes stay neutral.
• The Builder submits code as the candidate implementation. Each iteration requires a new read-only Verifier to assess every acceptance item independently. Assessing every item does not mean rerunning every command: reuse Runtime check records that still match the current candidate and add only missing or invalidated checks. Failed, blocked, unexecuted, and timed-out work cannot count as passed.
• Run confirmation commands only after the user explicitly confirms the complete Shape, accepts the final result, or selects the relevant delivery option. Reuse confirmed scope and user choices saved by Runtime. Authorization for Archive, merge, push, PR creation, and workspace cleanup is not interchangeable.
• This Skill and Runtime provide the Native workflow without an external Skill dependency. The Agent chooses implementation methods that preserve confirmed requirements and constraints.

Start or resume

1. If the name is known, run comet native select <change-name> --json. When an active change exists, enter the returned workspace.projectRoot; select returns the same discovery and state information as status, so a separate status call is not needed. Otherwise run comet native status --json. Let Runtime locate the workspace; ask the user only when multiple workspaces match equally well.
2. If there is no matching active change, select isolation and create it using workspace selection, then enter preparation.projectRoot. If preparation fails, preserve any branches and directories already created and address the reported cause.
3. After entering the workspace and obtaining phase, retrieve context once using memory integration. Expand details only when needed, record actual use outcomes, handle Project Memory and Personal Memory separately at task completion, and call comet task --complete as specified there.

Never save task summaries, progress, command output, or test results as Personal Memory; complete the learning check.

Project experience and personal preferences are stored separately: before task completion, write project-validated and reusable experience to Project Memory with comet knowledge remember; only user preferences and stable collaboration habits go to Personal Memory. See memory integration for the commands and completion conditions.

Read only what the action needs

Read the section for the current action. Follow links within it only when their stated conditions apply; do not load the entire command reference or all references at once.

• Shape: read and follow clarification, using Sequential or Batch steps according to project configuration. For large requests, follow its Supervisor decomposition and confirmation link before final confirmation.
• Before editing the brief, Specs, or children.yaml, or checking an acceptance report, read formal artifacts. A file, attachment, link, or local path supplied as a requirements source requires source-document full coverage. Material used only for debugging, evidence gathering, review, or implementation reference does not trigger this automatically.
• Before first filling a Runtime template or returning a result through returnAction, read filling command inputs.
• Before submitting a Builder candidate, read Builder handoff. Before launching, adding checks for, or waiting on a Verifier, read Verify protocol.
• When state contains childSummary, read Supervisor coordination before dispatching, receiving results, or integrating. Handle only children listed in readyChildren and Supervisor coordination actions.
• If fields are unclear, input is rejected, a Verifier is unavailable, execution fails, or external information is missing, read command inputs and exceptions. For normal actions, use Runtime's returned commands and templates directly.
• When waiting for external input, follow external input and monitoring; continue independent work. For interruption, a device change, repeated lack of progress, concurrency conflicts, failed migration, or damaged state, read fault recovery.

Shape

Investigate facts that can be established without the user. Ask only about decisions that change user-visible outcomes and cannot be inferred reliably. For simple requests, list unresolved questions and dependencies; maintain a decision tree only when several decisions affect one another. Before asking under native.clarification_mode, save this round's unresolved questions in the brief. Immediately copy confirmed conclusions into the relevant brief sections and complete target Specs. Keep unanswered parts [blocking].

Complete when requirements sources are fully processed within the coverage boundary and classified by purpose, all outcome-affecting decisions and assumptions are resolved, no [blocking] remains, the user explicitly confirms the outcome, scope, key decisions, all acceptance items, and non-goals, and Runtime has entered Build.

New or reconfirmed briefs need outcome, scope, non-goals, and acceptance examples. Add constraints, decisions, open questions, or special verification requirements when applicable. Runtime also checks formal paths and a complete target Spec or concrete no-product-behavior-change reason. Repair reported artifacts and rerun continuation. Existing later-phase changes retain progress until Shape.

Build ↔ Verify Loop

After the Builder submits a candidate, Runtime runs required checks and a new read-only Verifier assesses it. On failure, return to Build, repair, and resubmit. Once every item passes, wait for the user to accept the result.

iteration counts implementation submissions; attempt counts Verifier launches for the same candidate. Runtime updates all counters. When consecutive failures or lack of progress reach configured limits, follow the latest instructions to wait for a user decision or address the blocker.

Build

Before the first implementation, read the current brief, complete target Specs, and every acceptance item. Edit project code and tests within confirmed scope. During repair, prioritize the Verifier's failed or blocked items and failed checks, then recheck other confirmed behavior before submission. previous_unresolved_ids identifies the repair focus; the next formal verification still covers every acceptance item.

Build, Verify, and Archive recheck formal bindings. New Shapes bind Markdown content: blank lines and soft wraps preserve confirmation; content, structure, code, link, or acceptance changes require reconfirmation. After an edit, Hooks check actual content before the next implementation write; Runtime also checks before advancement. Existing Shapes retain their binding. Invalid documents or reports return repair actions and preserve work. Ordinary documents preserve candidates by default; use native.document_writes: revert for strict behavior. See formal artifacts for paths.

User Hook output can use hook.allow_paths in .comet/config.yaml; see User Hook writes.

Classify requirement changes before taking an action allowed by the current continuation:

• Missing implementation of confirmed functionality: use --revise-implementation from Verify, retain confirmed scope, and return to Build.
• Changed user-visible behavior or acceptance criteria: use --revise-requirements from Verify or Archive-ready, update formal artifacts, and reconfirm Shape.
• Unrelated requirements: use another change.

Apply the same rules when the user explicitly adds to the current scope.

One confirmed Supervisor Shape authorizes all children within that scope. Dispatch and integrate as Runtime directs, then automatically perform final verification of every Supervisor acceptance item. Follow Supervisor coordination for coordinator, Builder, and Verifier responsibilities. A child is complete only after Runtime accepts its verification and confirms integration.

Complete when the implementation and relevant checks are ready for verification, Runtime accepts the Builder handoff, and the phase is Verify.

Verify

Launch a new read-only Verifier immediately under the Verify protocol with the unchanged task package. Report it as running only after the platform accepts startup and the Verifier reports verifier-started; handle launch failures immediately. Use inline acceptance text or page through every scopeId. The Verifier assesses all acceptance items independently, reuses Runtime checks matching implementation, workspace, and inputs, and adds missing or invalidated evidence. Read files and logs on demand.

After a wait-tool timeout, keep waiting for the same Verifier. If its receipt is missing and it is unresponsive, check launch success. Report errors only for confirmed failure, execution timeout, task loss, or completion without a usable result. Follow current state after Runtime accepts results. Run --accept-result only after explicit user acceptance, including automated-check-only results. For isolated workspaces, accept results and choose delivery in one reply with --finish; ask separately if no finish was chosen.

Complete when Runtime accepts each verdict and supplies the next action. Continue repairs on Build, or address the specified waiting or blocking condition. Ending a phase does not mean the task is finished.

Archive

When continuation permits Archive, read Archive completion, reuse the accepted result, and follow continuation. After an explicit finish choice, execute its complete --confirmed --finish command; Runtime preflights and rechecks the transaction. If dry-run is returned, preview and run its unique confirmed command after ready: true. Address the returned blockers.

Commit only this change's implementation and formal artifacts; preserve unrelated edits. Inspect workspaceFinishResult, preserving the workspace and following recoveryArgs if blocked. Fix commit messages and local blockers under existing authorization and continue; ask only for new authorization or external information.

Complete when state is done, authorized workspace finishing is completed or kept, and task completion has been recorded through memory integration. Continue handling any other result.

Continuation

• continue: execute the complete commandArgs in the returned working directory and fill inputs from inputOptions templates.
• await-user: relay userCommunication.message and suggestedReply, then wait for the listed decisions. Execute the matching commandAlternatives, retaining --expected-state-version and --expected-action. Read the latest state if stale; do not construct an unguarded command.
• blocked: address listed blockers or recovery actions; pause only dependent work.
• done: finish after checking the Archive completion criteria.

After a successful response containing agent, reuse the shared workflow guard's lightweight ownership result and continue with the response's phase, state version, workspace.cwd, and continuation. Read details only when fields are missing, the command is rejected for version or ownership, or the action needs additional artifact text. Query status again only for a new session or compression recovery without response state, a repository/branch/change switch, or clear external changes. Do not redispatch an existing Verifier or child task because a wait tool timed out.

Add --details only when the current action needs acceptance text, handoff summaries, or history. Follow nextPageArgs through every page covering scopeIds. Run show only when artifact bodies are needed. For CLI text, read summary, the single NEXT:, and any relay message first. Use --json for programmatic parsing and --verbose only to diagnose local execution.
