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 | $0.00051 | $0.00338 |
| Opus 5 | $0.00026 | $0.00169 |
| Sonnet 5 | $0.00010 | $0.00068 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
post-forge-feature 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 2d 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.

What it actually says
Post ForgeCode Feature
Generate a punchy, developer-friendly Twitter/X post for a ForgeCode feature. The post always accompanies a video, so no need to describe every detail; the video does the showing.
Workflow
-
Understand the feature: use tools to read the relevant source code, docs, or changelogs. Answer:
- What does it do?
- When would a developer reach for it?
- What pain does it remove?
-
Craft the post: follow the constraints in
references/style-guide.md. -
Present for approval: show the post and ask if the user wants tweaks before finalizing.
Key Constraints
- 2-3 sentences max (fits ~280 chars).
- No filler phrases ("excited to announce", "game changer", "introducing").
- Always refer to the product as "ForgeCode", never "Forge" alone.
- No em dashes anywhere in the post.
- Lead with the developer benefit or the problem solved, not the feature name.
- The video is attached. Do not say "watch the video" or describe what is in it.
- End with a relevant hashtag line (see style guide for approved tags).
Reference Files
references/style-guide.md: tone, vocabulary, approved hashtags, and example posts. Read this before drafting.
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.
