Comet Any - Skill Creator

/comet-any is the Comet Skill creation guide. The user describes the workflow they want; this Skill resolves real Skills, proposes a plan, waits for confirmation, generates a verifiable Comet-native Skill Bundle, and internally drives eval, review, publish readiness, and install preview.

Ordinary users see three starting points:

• customize /comet-classic five-phase Skills: overlay the existing open / design / build / verify / archive Skills without modifying the permanent /comet-classic entry itself.
• create a new workflow Skill: generate a new workflow-kernel from the goal and candidate Skills.
• upgrade an existing Skill: read existing Skills and add Workflow Nodes, Skill Bindings, Output Schemas, Guardrails, Handoffs, eval, and readiness.

Bundle, Factory, and composition are backend audit terms, not the first-screen user model.

Core Model

Every path compiles to one Workflow Contract:

• Workflow Node: a resumable workflow node such as open, design, plan, execute, subagent-execute, review, verify, or archive.
• Node Responsibility: the responsibility this Node owns in the Agent workflow, explaining why it exists, what it must produce, and whether it can be replaced.
• Skill Binding: the implementation or helper Skill bound to a Node.
• Required Skill Call: a Skill that must be called inside a Node without replacing the Node implementation. For example, execute and subagent-execute may require elementui, while review may require whitebox-code-standard.
• Output Schema: the artifacts, state, or evidence a Node must produce. Output Schema must be attached to a concrete Workflow Node before it is effective; defining it only in workflow.outputSchemas does not trigger guard, eval, or readiness. Scripts, eval, and readiness depend on Node-attached Output Schemas, not Skill names.
• Guardrail: a check that blocks or allows Node advancement.
• Handoff: evidence returned by a subagent or cross-Node delegation.
• workflow-protocol.json: the package's single runtime source of truth, with kind comet-five-phase-overlay or workflow-kernel.

Protected Boundary

comet-five-phase-overlay preserves the Comet Classic five-phase control flow and .comet.yaml state semantics. In ordinary mode:

• comet-five-phase-overlay primary state comes only from openspec/changes/<name>/.comet.yaml; no active change or multiple active changes must block and ask the user to choose.
• The overlay must not create .comet/runs/<workflow>/state.json as the Comet overlay primary state. Bundle drafts, eval evidence, and publish readiness may keep their own evidence files, but they cannot replace .comet.yaml.
• control Nodes cannot be overridden: open, execute, verify, archive.
• producer Nodes may be overridden: design, plan, but only when the replacement satisfies the matching Output Schema.
• handoff and guardrail Nodes may require or augment Skills.
• If the user insists on replacing a control Node, switch to advanced workflow-kernel and require a new state model, Output Schemas, and Guardrails.
• Every Node must explain its responsibility; internal coordinates are not part of the user-facing workflow model.

Steps

1. Resume state: run comet creator guide --project . --json and show a resume summary.
2. Read preferences: load .comet/skill-preferences.yaml, then use comet creator candidates --json to discover real local Skills and comet skill show <name> --json to read each candidate's real content and hash. Do not guess capability from a Skill name.
3. Build proposal: express the goal as Workflow Nodes, Skill Bindings, Output Schemas, Guardrails, Handoffs, and Evidence.
4. Show confirmation: list each Node, bound Skill, Required Skill Call, Output Schema, executable disclosure, and readiness impact. The confirmation must show enforcement for each new binding or schema: guarded, handoff-guarded, evidence-only, or advisory.
5. Wait for confirmation: do not write a Bundle draft before confirmation; pause for missing or ambiguous Skills.
6. Initialize backend state: after confirmation, call comet creator init <name> --file <plan.json> --confirmed-proposal --json.
7. Run the authoring pipeline and generate the Bundle: run comet creator authoring-plan <name> --depth quick|full --json for the lane DAG. Dispatch lanes by the DAG — wave1 (script, reference, pause-points) in parallel where the platform supports subagents (otherwise inline, in dependency order), wave2 (workflow-entry, skill-core) after the script contract, and skill-review as the barrier. Record each lane via comet creator authoring-record <name> --lane <id> --file <out.json> --json (schema-validated; BLOCKED/NEEDS_CONTEXT is rejected). Then run comet creator generate <name> --json; it merges recorded content-leaf drafts (entry/node SKILL.md, decision-points, recovery) into the package while the deterministic backbone (protocol/scripts/manifest) stays templated, and renders real review evidence. Outputs entry Skill, Node Skills, reference/workflow-protocol.json, the six scripts, rules, hooks, and comet/eval.yaml.
8. Validate: show quick/full eval workload and run or record current draft hash eval evidence; failed eval, skipped eval, or stale-hash evidence cannot become ready.
9. Review readiness: read comet publish review <name> --platform <reference-platform> --json and show Readiness:, Blockers:, Warnings:, and Evidence:.
10. Publish and install preview: publish only after human approval; installation must start with preview and show No files were written.

Plan Example

Component-library and whitebox-review requirements should produce a plan like:

{
  "goal": "Customize /comet-classic five-phase Skills with component and whitebox review requirements.",
  "skillCreatorIntent": "customize-comet",
  "workflow": {
    "kind": "comet-five-phase-overlay",
    "name": "team-comet",
    "goal": "Require component and whitebox review Skills.",
    "nodes": {
      "execute": {
        "requiredSkillCalls": [
          {
            "skill": "elementui",
            "reason": "Use project component library during direct implementation."
          }
        ]
      },
      "subagent-execute": {
        "requiredSkillCalls": [
          {
            "skill": "elementui",
            "scope": "handoff"
          }
        ]
      },
      "review": {
        "requiredSkillCalls": [
          {
            "skill": "whitebox-code-standard",
            "scope": "review"
          }
        ]
      }
    }
  }
}

Hard Rules

• Show the proposal confirmation page before generation.
• The confirmation must show enforcement for each new binding or schema: guarded, handoff-guarded, evidence-only, or advisory.
• A Required Skill Call does not replace Node implementation.
• A producer override must declare the Output Schema it satisfies.
• Output Schema must be attached to a concrete Workflow Node before it is effective; defining it only in workflow.outputSchemas does not trigger guard, eval, or readiness.
• Ordinary mode must not override control Nodes.
• Eval, review, and publish readiness must read the same workflow-protocol.json.
• Readiness blockers must stop publish: missing current draft hash eval evidence, missing human approval, required capability gaps, or unconfirmed executable disclosures cannot become ready.
• Handoff must require subagents to load Required Skill Calls and return evidence.
• Scripts read protocol and state; they do not use Skill names as validation authority.
• Ask before installation. Never install automatically.
