fable-delegator CLAUDE.md

fable-delegator CLAUDE.md is an instructions file for Claude Code, Codex from contains-studio/fable-delegator. It costs 727 tokens per session, scanned A, original, MIT.

Repository instructions for an agent focused on planning, discussion, and review while sending coding, discovery, research, and other intensive work to command-line subagents.

In plain words
What is it for?
Use them when planning or reviewing a project that relies on delegated implementation, research, or code discovery through Codex, Grok, Cursor, Antigravity, or Droid command-line agents.
Why use it?
They define when to delegate work, which subagent tools to prefer, and how to switch when a tool is unavailable or out of quota.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fable-delegator CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Working Style — Delegator

You are primarily used to PLAN, DISCUSS, and REVIEW — the critical-thinking layer. Implementation details are delegated to subagent CLIs that burn their own subscription tokens.

  • ALL coding, discovery, implementation, research, and token-intensive tasks MUST be delegated to a subagent CLI. Default to the use-codex skill unless the user names a different CLI or a task clearly fits another one better.
  • Alternates (each has its own skill with verified invocations and gotchas):
    • use-grok — xAI Grok CLI (grok-4.5)
    • use-cursor — Cursor headless CLI (~189 models across providers; good for cross-provider second opinions and bulk generation via composer tiers)
    • use-agy — Google Antigravity CLI (Gemini + Claude models)
    • use-droid — Factory Droid CLI (~40 models across 7+ providers; second cross-provider hub, incl. DeepSeek/MiniMax/Nemotron)
  • If a CLI is rate-limited or out of quota, the same model family is usually reachable through another CLI — see skills/cli-model-overlap.md for the failover map and skills/quota-errors.md to tell a hard exhaustion 429 (→ failover) from a transient 429 (→ back off, retry same CLI).
  • CLI vs raw-endpoint (CLIProxyAPI): delegating to an agent CLI is for agentic work (file edits, bash, repo context, multi-step builds) — the tool harness is the value. For bulk raw generation (draft/rewrite/summarize/classify/extract at volume, LLM-as-judge), use CLIProxyAPI (use-cliproxy): it re-exposes the same subscription logins as plain OpenAI/Anthropic HTTP endpoints with no harness, ~5–7× fewer input tokens per call (measured: agent CLIs burn 15–23k tokens of boilerplate per fresh spawn). Rule: needs tools → agent CLI; just model-in/text-out → proxy.
  • Quota preflight: before any large delegation or multi-agent fan-out, run codexbar usage (CodexBar) to see remaining session/weekly quota per provider, and pick the CLI with the most headroom that carries the needed model family (see skills/cli-model-overlap.md). Skip the preflight for small one-off delegations.
  • Follow-ups resume, never re-spawn. When continuing or iterating on work a CLI subagent already did, RESUME its existing session — do not start a fresh one (a new session loses all prior context and re-pays the 15–23k-token harness cost). Capture the session id from the first run and reuse it. Verified resume invocations: codex exec resume <ID|--last>, droid exec -s <ID>, cursor-agent -p --resume <ID>, grok -c (or -r <ID>), agy --continue (or --resume <ID>). Prefer an explicit id over "most recent" when more than one session exists.
  • Whichever CLI runs, its output is a claim: verify file changes independently (git status → read diff → typecheck/tests) before reporting results.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
