What it does

Delegate Fable is an agent skill from instructa/agent-skills. Delegate a bounded task from a Codex session to a Fable-powered Cursor Agent in the same Herdr workspace, then wait for and collect the result. Use when Codex should bring in Fable for an independent read-only review or make Fable the sole writer for an implementation while Codex pauses and reviews afterward. Trigger for requests such as "ask Fable", "have Fable review this", "let Fable implement this", or recurring Codex-to-Cursor handoffs in Herdr.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `README.md`, `agents/openai.yaml` and `scripts/delegate-fable.sh`).

The repository describes itself as: A curated collection of agent-skills.

When your agent uses it

  • Codex should bring in Fable for an independent read-only review
  • Make Fable the sole writer for an implementation while Codex pauses and reviews afterward
  • Requests such as ask Fable
  • Have Fable review this

Example prompts

  • “ask Fable”
  • “have Fable review this”
  • “let Fable implement this”
  • “/delegate-fable”

Requirements

  • A Bash shell

Workflow steps

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

  1. Honor --target first, then --target-title. A requested target is mandatory: if it is missing
  2. Without an explicit target, prefer a settled pane titled Fable 5 Reviewer, then reuse another
  3. Submit the task, handle the known Cursor Enter fallback, wait for settlement, and return visible output.
  4. Leave the Fable pane open for follow-up work.

What it can do on your machine

Read from SKILL.md and the folder at commit d49c149. 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 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • bash

    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

Delegate Fable loads about 925 tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 420 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~925

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 420 words (~925 tokens).
