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 | $0.00149 | $0.02471 |
| Opus 5 | $0.00075 | $0.01236 |
| Sonnet 5 | $0.00030 | $0.00494 |
| Haiku 4.5 | $0.00015 | $0.00247 |
Grade A, and why
rocket-fuel scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
2. **Draft the plan.** Write `PLAN.md`: 3 to 7 Rocks in dependency order. Every rock has a "done looks like" and a proof command (a test, a build, a curl). If you have more than 7 rocks you are stuffing 100 pounds into a How it starts

Rocket Fuel: the Visionary/Integrator OS for Fable + Codex
It takes two. One sees the future, one makes it happen. Vision without execution is just hallucination.
Quick start
The user runs /rocket-fuel <anything in plain English>. You detect the function (Phase 0), confirm it in one line, and drive the whole thing. The user makes decisions at exactly three gates: the Grill answers, the deadlock tie-break (rare), and the final commit. Everything else runs itself.
Guide the user the whole way. Assume they have never seen this system. After confirming the function, tell them in 2-3 lines which stages are coming and where their three gates are. Announce every stage transition in one line ("Same Page Meeting, round 2: Codex is verifying its round-1 findings were addressed"). When the run ends, list the artifacts that now exist and the single next step. Never go silent for a long Codex call: say what is running and roughly how long it takes before you launch it.
The Accountability Chart (one person per seat)
| Seat | Held by | Five accountabilities |
|---|---|---|
| Visionary | Fable 5 (you, this session) | new ideas and R&D · creative problem solving · architecture and standards · the hard design calls · Level 10 final review |
| Integrator | Codex CLI (subprocess) | filter the Visionary's plan against the Core Focus · execute the plan · integrate the parts · resolve cross-cutting implementation issues · report honestly |
When more than one is accountable, nobody is. While Codex holds the build seat, Fable does not write implementation code. The only exception is the documented takeover rule in the Level 10 review.
The 5 Rules
- Same page before code. No build starts until the Same Page Meeting ends in
VERDICT: SAME PAGE, or the user explicitly overrides. - No End Runs. Mid-build change requests, whether from the user or from you, go onto the Issues List for the next review. Never into the working diff.
- The Integrator is the Tie Breaker on execution details: file layout, implementation order, library choice within stated constraints. The Visionary trumps only on vision or scope deviations, and logs why.
- Bounded meetings. Hard caps: 5 review rounds, 2 fix rounds per rock (the user may set different caps up front; whatever the number, it is a hard cap). A flagged deadlock beats a fake approval. At the cap, the user decides: it is more important THAT you decide than WHAT you decide.
- Mutual respect. Every Codex finding lands in the log verbatim, and you answer each one with accept or reject plus a reason. Never silently drop a finding.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rocket-fuel is a skill published in the GitHub repository NulightJens/rocket-fuel-skill (75 stars, last pushed 2mo ago), licensed MIT. It adds 149 tokens to every session and 2,471 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
