What it does

Comet is an agent skill from rpamis/comet. Comet workflow entry. Use when the user invokes /comet or asks to use Comet without choosing Native or Classic; load Native or Classic from project configuration.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 26 other files, including scripts (for example `agents/openai.yaml`, `rules/comet-phase-guard.en.md` and `rules/comet-phase-guard.md`).

The repository describes itself as: Comet: agent skill harness for turning ideas into evaluated workflows. The licence is MIT.

When your agent uses it

  • The user invokes /comet
  • Asks to use Comet without choosing Native
  • Classic from project configuration

Example prompts

  • “/comet”

Requirements

  • Node.js

Workflow steps

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

  1. Run the Comet CLI installed on PATH in the current project
  2. Parse the JSON. Only accept schema: comet.workflow-resolution.v1 and one of the two skill values below.
  3. Immediately use the Skill tool to load the entry named by skill. Load exactly one entry

What it can do on your machine

Read from SKILL.md and the folder at commit 0fd42a0. 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

    Ships 7 files in scripts/ (JavaScript, from the files we listed), which the agent can run.

    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 loads about 686 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 359 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~686

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); the scripts in this folder are not scanned.

Comet workflow entry. Use when the user invokes /comet or asks to use Comet without choosing Native or Classic; load Native or Classic from project configuration.

Comet Entry

/comet selects Native or Classic from project configuration, then passes the request to that workflow's Skill.

Once this Skill is loaded, immediately follow the steps below. The user has already chosen Comet: continue their request without reconsidering whether to use it or merely explaining why you would not proceed.

  1. Run the Comet CLI installed on PATH in the current project:

    text
    comet workflow resolve . --activate --json

    If the project has no .comet/config.yaml, this command saves the global defaults in the project and creates the configured artifact directories. Later changes to global defaults do not overwrite this project's saved configuration.

    On command not found, executable not found, or ENOENT, stop and report an incomplete Comet CLI installation. Do not search for Skill files, scan platform configuration directories, or invoke an internal bundle directly.

    If the CLI starts but exits nonzero, cannot parse the configuration, or returns invalid JSON or fields, preserve the original error and stop. Do not choose another entry yourself.

  2. Parse the JSON. Only accept schema: comet.workflow-resolution.v1 and one of the two skill values below.

  3. Immediately use the Skill tool to load the entry named by skill. Load exactly one entry:

    • /comet-native → Execute immediately: Use the Skill tool to load the comet-native skill. Do not skip this step.
    • /comet-classic → Execute immediately: Use the Skill tool to load the comet-classic skill. Do not skip this step.

    Pass the user's original request unchanged to that Skill.

After workflow selection, the selected Skill locates the change's workspace and current phase, then loads task context, personal memory, and project knowledge; use comet memory context when needed.

Load context as needed. First use comet task ... --json to obtain a Context Manifest containing only summaries, reasons for recommending each item, and stable IDs. Add --expand-context "<id>" when the step needs the full text, source, or verification method.

After using an item and establishing its outcome, report the actual result with its returned application ID: --application "<application-id>" --outcome used-successfully|ignored|overridden|corrected|contributed-to-failure. Do not report successful use of an item that was not used.

Do not switch workflows based on task size, file count, active changes, or model judgment. Native and Classic manage their own changes, state, and artifacts.
