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 | $0.00183 | $0.06291 |
| Opus 5.5 | $0.00073 | $0.02516 |
| Sonnet 5.5 | $0.00037 | $0.01258 |
| Haiku 4.5 | $0.00018 | $0.00629 |
Grade A, and why
autostar 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 1mo 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 — 645 lines — stays where its author put it; the contents beside it link to each section on GitHub.
a* (autostar)
A generalised autonomous optimisation loop — soft RLVR for the masses. The user defines a goal; the system runs structured experiments, evaluates progress across independent tracks, reflects at strategic checkpoints, and learns from every attempt — including learning how to learn better the next time.
If you can measure it, you can improve it.
Experimental-first principle
a* is an experimental optimisation loop. Do not reach for external mathematical
optimisers or solvers (e.g. scipy.optimize, cvxpy, linear/quadratic
programming solvers, evolutionary algorithm libraries, Bayesian optimisation
frameworks, or any other off-the-shelf optimisation package) as a shortcut to
improving the artifact. The value of a* is in the structured
explore-evaluate-reflect cycle, not in delegating the search to a solver.
If at any point during onboarding, pre-run analysis, or execution you believe the problem is well-suited to a closed-form or mathematical optimisation approach, you must ask the user first before pursuing it. Present it as an alternative:
"This problem looks like it could be approached with a mathematical optimiser (e.g. [specific method]). Would you like me to try that instead of running the experimental loop, or would you prefer to proceed with a*?"
Do not silently install, import, or invoke an external optimiser. Do not reframe the a* loop as a wrapper around a solver. If the user explicitly opts for a mathematical approach, that is a different workflow — not an a* run.
Concepts
Before running, ensure you understand these terms precisely:
| Term | Meaning |
|---|---|
| Step | One execution with one parameter set. Atomic unit of work. |
| Play | A named bundle of parameters that move together (optional; disable with plays: false). |
| Lap | A set of steps sharing the same parameter family. Establishes statistical confidence in a direction. |
| Round | A set of laps. Ends with a mandatory reflection: worth pursuing? ask user? pivot? |
| Run | One user-initiated process. Lasts until budget is exhausted or goal is met. |
| Track | One independently verifiable sub-goal. Has its own verifier and ratchet. |
| Disposition | A learned prior on how to approach a (problem class, action intent) pair. Stored in long-term memory; conditions all significant actions. |

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.
- 1mo ago First seen · 645 lines · 183 tokens per session scan A 51513c013ef8
autostar is a skill published in the GitHub repository chrisvoncsefalvay/autostar (39 stars, last pushed 6mo ago), licensed MIT. It adds 183 tokens to every session and 6,291 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-08-30.
