What it does

Comet Any is an agent skill from rpamis/comet. Create or upgrade a Comet Classic workflow Skill via Comet Creator. Not for general Skill authoring, cleanup, or review.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files (for example `agents/openai.yaml`, `reference/authored-zone-example.md` and `reference/authoring-protocol.json`).

It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: Comet: agent skill harness for turning ideas into evaluated workflows. The licence is MIT.

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  9. Review readiness: read comet publish review --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.

What it can do on your machine

Read from SKILL.md and the folder at commit c28e724. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Comet Any loads about 2k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 911 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 <classic-change-dir>/.comet.yaml bound by the Classic layout resolver; 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 — dispatch wave1 (script, reference, pause-points) in parallel, dispatch wave2 (workflow-entry, skill-core) in parallel after the script contract, and run 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:

json
{
  "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.
