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 | $0.00028 | $0.00222 |
| Opus 5 | $0.00014 | $0.00111 |
| Sonnet 5 | $0.00006 | $0.00044 |
| Haiku 4.5 | $0.00003 | $0.00022 |
Grade A, and why
forge-isolate 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 4d 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
Forge Isolate
Activates: after intent doc approved.
Steps
- Confirm design draft exists in
docs-ai/designs/drafts/{slug}.md - Create branch:
forge/{slug}from updatedmain - Optional worktree (parallel work):
git worktree add ../ratary-{slug} -b forge/{slug}
cd ../ratary-{slug} && npm install
- Run baseline:
npm test— record pass count; stop if red on main-equivalent baseline - Report: branch path, worktree path (if any), test count
Rules
- Never implement on
maindirectly for multi-step forge work - If baseline fails unrelated to your task, diagnose first (
forge-diagnose)
Cleanup hint
Worktree removal happens in forge-land.
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.

forge-isolate is a skill published in the GitHub repository ontorata/ratary (1 stars, last pushed 25d ago), licensed MIT. It adds 28 tokens to every session and 222 once invoked, about $0.0001 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.
