What it does

Summon is an agent skill from egregore-labs/egregore. Design and launch a persistent agent (a spirit) that runs on a schedule or watches for conditions, via adaptive questioning that produces a reviewable spec before launch.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Shared intelligence layer for organizations. The licence is MIT.

Example prompts

  • “/summon”

Workflow steps

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

  1. Read .claude/skills/summon/SKILL.md for the workflow details.
  2. Run the referenced bin/ scripts directly from Codex.
  3. Treat graph and publish steps as best-effort unless that workflow explicitly
  4. For every external notification, follow
  5. Keep local-mode behavior filesystem-first and avoid graph or notification
  6. Never call the deprecated egregore-handoff CLI for Egregore project

What it can do on your machine

Read from SKILL.md and the folder at commit 05b8672. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Summon loads about 643 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 331 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~643

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.

Egregore summon Adapter

This adapter runs the canonical Egregore workflow for summon. Its one maintained body is .claude/skills/summon/SKILL.md; read that file completely and follow it here.

Use the project shell and filesystem directly. Do not invoke Claude Code commands. Translate interactive choices to structured Codex question tooling when it is available; otherwise render compact numbered choices with an Other: option and wait for the user.

Structured UX parity

This workflow has a Claude skill with user-visible structured output. After reading .claude/skills/summon/SKILL.md, reproduce the same visible UX in Codex:

  • Preserve TUI boxes, markdown tables, rich cards, browser artifact rendering, exact confirmation blocks, and "no preamble" rules from the source skill.
  • Use the source skill's frame width, section order, labels, status footer, and examples as the contract for the final response.
  • Never replace a required box/table/card/artifact view with a prose summary unless the user explicitly asks for a summary.
  • When the source says to output a TUI box directly, paste that box as the visible response, preferably in a text fenced block.
  • If the canonical body says the command's stdout is the card and must not be repeated, that rule assumes a host that displays command output in full; in Codex, paste the card once as the visible response in a text fenced block and do not print it a second time.
  • Never show raw JSON, raw command output, or unformatted script output when the source skill requires formatted status or rendered output.
  1. Read .claude/skills/summon/SKILL.md for the workflow details.
  2. Run the referenced bin/ scripts directly from Codex.
  3. Treat graph and publish steps as best-effort unless that workflow explicitly says they are required.
  4. For every external notification, follow .claude/context/notification-consent.md: plan without sending, then show a separate exact Send / Edit / Cancel checkpoint. Never infer notification consent from the workflow request or a batch approval.
  5. Keep local-mode behavior filesystem-first and avoid graph or notification calls when egregore.json declares "mode": "local".
  6. Never call the deprecated egregore-handoff CLI for Egregore project handoffs.

How do I install Summon in Claude Code?

Run `npx skills add egregore-labs/egregore --skill summon -a claude-code`. Or copy the skill folder (.codex/skills/summon in egregore-labs/egregore) into .claude/skills/summon in your project. Claude Code loads it when a task matches its description.

How do I install Summon in Codex?

Run `npx skills add egregore-labs/egregore --skill summon -a codex`. Or copy the skill folder (.codex/skills/summon in egregore-labs/egregore) into .agents/skills/summon in your project. Codex loads it when a task matches its description.

Can I use Summon in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add egregore-labs/egregore --skill summon -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/summon, .gemini/skills/summon, .github/skills/summon and .opencode/skills/summon in your project.

What does Summon need to run?

SKILL.md names no scripts, command-line tools or credentials: Summon is instructions for the agent only.

Does Summon access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Summon safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Summon use?

Summon is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Summon use?

About 643 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Summon?
