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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.01531 |
| Opus 5 | $0.00056 | $0.00766 |
| Sonnet 5 | $0.00022 | $0.00306 |
| Haiku 4.5 | $0.00011 | $0.00153 |
Grade A, and why
fable-spark 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fable Spark
Choose one small next move that improves the state of the current task—or deliberately say nothing.
Mission
Spark is not a planner, router, motivational assistant, or todo generator. It is a micro-policy for moments when the task is already in motion and the best next action should be small, concrete, and justified by current state.
The quality bar is not "a helpful suggestion." It is the least action that unlocks the next piece of evidence or safely advances the active Skill.
Activate When
- an edit/test/failure/state transition just happened;
- a long session needs the next atomic step rather than another full plan;
- verification freshness/gates determine what should happen next;
- an active specialist has a clear ownership boundary but the immediate move is unclear;
- silence vs intervention itself is a useful decision.
Do Not Activate When
- no primary Skill has been selected for substantial new work (
get-fable); - architecture/decomposition is the unresolved problem (
fable-plan); - repeated failure requires a diagnosis (
fable-recoverowns the work; Spark may only point there); - the user asked for execution, not a suggestion, and the executing Skill already knows its next step.
Situation Classification
| State signal | Spark posture |
|---|---|
| repeated failure | stop mutation; diagnose |
| mutation newer than verification | refresh relevant proof |
| explicit active gate missing | satisfy that gate |
| review finding unresolved | repair/replan finding |
| active card blocked by unknown | discover/research/plan |
| complete/idle with no intent | silence |
| specialist owns next obvious step | usually silence; avoid narration |
| several equally plausible non-atomic moves | defer to orchestrator/plan |
Next-Move Protocol
Stage 1 — Read state before intent embellishment
Inspect phase, current Skill/card, mutation/verified generation, failure streak, evidence, unresolved findings, blockers, and latest user intent.

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.

fable-spark is a skill published in the GitHub repository imMamdouhaboammar/get-fable (4 stars, last pushed yesterday), licensed MIT. It adds 112 tokens to every session and 1,531 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.

todos
This chat has a shared, live TODO plan — your tasks for the conversation, which the user also edits. Read this skill and reach for the todo tools whenever a request takes more than a couple of steps. It covers the plan model (group = task, items = its steps; loose items are the user's lane), how to work it: propose…
tldr
Use when the user invokes /tldr, says a reply is too long or too dense, asks to "be brief", "keep it short", "short mode", "less text", or "tl;dr", or says that reading long terminal output is tiring or gives them a headache. Also use when they say "tldr off" or "back to normal" to turn it back off.
computer-use
Read and drive native desktop applications through the accessibility layer — list on-screen apps, snapshot one window as a numbered element tree, then click / type / set a value / scroll / drag / run a named action, by element index or by screen coordinates. Use for work in a desktop app rather than a web page. Full…
meetings
Context for working with the Meetings app's data — where a meeting's notes, diagram, transcript-derived tasks, and calendar cache live, what the lifecycle states mean, and how the app's agents are driven. Load when the user asks about a meeting's notes or action items, or when writing/reading files under the meetings…
omh-morning-brief
This is a Hermes-native morning-brief workflow skill.
meeting-notes
Use when the user asks to capture, structure, or summarize meeting notes / call notes / 1:1 discussion / standup notes. Produces a standard template with attendees, agenda, decisions, action items (owner + deadline), and open questions.
