At a glance

A skill your agent uses when choosing between cheap probes, worker runs, expensive ruler runs, or long keepalive waits.

  • Choosing between cheap probes
  • SKILL.md covers Mechanism, Ruler, Cache and Ledger
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Expensive ruler runs

What it does

Run Economics is an agent skill from 100yenadmin/fable-token-saving-skills-orchestrator. Use when choosing between cheap probes, worker runs, expensive ruler runs, or long keepalive waits.

Its SKILL.md is about 230 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: 🧚 Fable-first Claude orchestration kit for token-saving lane routing, dense turns, and cache-preserving wait discipline. The licence is MIT.

When your agent uses it

  • Choosing between cheap probes
  • Expensive ruler runs
  • Long keepalive waits

Example prompts

  • “/run-economics”

What it can do on your machine

Read from SKILL.md and the folder at commit cf1d9a3. 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

Run Economics loads about 226 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 113 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~226

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.

Run Economics

Match the instrument to the question.

Mechanism

Use cheap probes when the question is "does this mechanism fire?"

Examples:

  • hook blocks stale wait
  • cue reaches worker
  • small parser case passes
  • one narrow acceptance test catches the bug

Ruler

Use premium runs when the question is "does this meet the bar?"

Examples:

  • release readiness
  • final quality score
  • customer-facing proof
  • hard architectural judgment

Cache

For short waits, preserve the prompt cache with a sleep-tick if no inline work remains. For long waits, let the cache die once. Do not ping through multi-hour idle windows by default.

Ledger

For scored or judged runs, record provider, model or lane, scenario, method, score, and proof boundary.
