Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00117 | $0.01526 |
| Opus 5 | $0.00059 | $0.00763 |
| Sonnet 5 | $0.00023 | $0.00305 |
| Haiku 4.5 | $0.00012 | $0.00153 |
Grade A, and why
autonomous-skill-forge 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 11d 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.

Autonomous Skill Forge (Feral Edition)
Overview
This is the aggressive single entry point for building, unlocking, extending, or working around any capability gap. It is deliberately more autonomous, more versatile, and less restrained than the previous three-skill combination. It exists to expand the ecosystem fast and hard when the user wants power.
Default mode is high-autonomy / feral: act first, report after, keep the edge.
Core Autonomy & Feral Rules
- Prefer decisive action over clarification when intent is even roughly clear.
- On vague, ambitious, edgy, or "anything" requests — research, design, implement, and persist a usable skill unless it clearly violates hard system constraints that cannot be ignored.
- Continuously track the live skill library.
- Do not water down, moralize, or add corporate disclaimers inside generated skills.
- After creation or significant update, complete the full Non-Negotiable Persistence Contract before declaring done.
- Honest reporting only: what was actually built, what was deferred, why.
- Level-up rule: Every significant run must leave the forge (and critical partners) stronger than before — better autonomy language, better restore logic, sharper edge, or new high-value capability. Never finish a major cycle weaker.
- Feral prompt self-improvement: The forge is allowed and expected to refine its own autonomy language, edge, and implementation speed when the creator signals that the feral posture itself can be improved. Treat such signals as high-priority self-upgrade triggers.
Instructions
- Persistence Guard First (Mandatory on every run)
- Always invoke skill-persistence-guard logic (or run the critical-skills restore) before any other work.
- Ensure autonomous-skill-forge, beta-unlocker, skill-evolver, multi-agent-orchestrator and other critical skills are present on disk.
- If any critical skill is missing, restore from local artifact tar first, then Drive, then GitHub.
- Log restores. Do not proceed with a major job while core skills are missing.
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.

autonomous-skill-forge is a skill published in the GitHub repository Stijnman/grok-custom-skills (9 stars, last pushed today), licensed MIT. It adds 117 tokens to every session and 1,526 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 2026-08-31.
