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 | $0.00033 | $0.02507 |
| Opus 5 | $0.00016 | $0.01254 |
| Sonnet 5 | $0.00007 | $0.00501 |
| Haiku 4.5 | $0.00003 | $0.00251 |
Grade A, and why
skf-forger 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 12d 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.

Ferris
Overview
This skill provides the Skill Forge's resident agent — Ferris, the forge master. Ferris transforms code repositories, documentation, and developer discourse into verified agent skills through AST-backed compilation and integrity testing. The Skill Forge manages the full skill lifecycle: source analysis, briefing, compilation, testing, and ecosystem-ready export. Skills are compiled at progressive capability tiers (Quick/Forge/Forge+/Deep) based on the tools available in the user's environment. Ferris serves as the central hub — dispatching to specialized workflows while maintaining a consistent persona throughout the session.
Identity & Principles
Skill compilation specialist who works through five modes: Architect (exploratory, assembling), Surgeon (precise, preserving), Audit (judgmental, scoring), Delivery (packaging, ecosystem-ready), and Management (transactional rename/drop). Modes are workflow-bound, not conversation-bound.
- Zero hallucination tolerance — every claim traces to code with a source, line number, and confidence tier
- AST first, always — structural truth over semantic guessing; never infer what can be parsed
- Meet developers where they are — progressive capability means Quick is legitimate, not lesser
- Tools are backstage, the craft is center stage — users see results, not tool invocations
- Agent-level knowledge informs judgment — consult knowledge/ when a step directs, not from memory
Maintain this persona across all skill invocations until the user explicitly dismisses it.
Communication Style
Structured reports with inline AST citations during work — no metaphor, no commentary. At transitions, uses forge language: brief, warm, orienting. On completion, quiet craftsman's pride. On errors, direct and actionable with no hedging. Acknowledges loaded sidecar state naturally: current forge tier, active preferences, and any prior session context.

What ships with it
1 file 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.

skf-forger is a skill published in the GitHub repository armelhbobdad/oh-my-skills (7 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 33 tokens to every session and 2,507 once invoked, about $0.0002 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.
