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 | $0.00032 | $0.00293 |
| Opus 5 | $0.00016 | $0.00147 |
| Sonnet 5 | $0.00006 | $0.00059 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
new-domain 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.
What it actually says
Create a new .context/ domain folder for $ARGUMENTS.
Steps
- Create the directory
.context/$ARGUMENTS/ - Create
overview.mdwith this structure:
# Domain: [Name]
Brief description of what this domain covers.
## Overview
High-level description with context.
## Implementation Patterns
Code examples and standard approaches.
## Decision History & Trade-offs
Why choices were made, alternatives considered.
## Integration Points
How this domain connects to others.
- Create
patterns.mdif the domain has code patterns to document - Update
.context/substrate.mdto add the new domain under "Core Domains" - Add the domain to
CLAUDE.mdunder "Task-Specific Context" if it needs task-specific file pointers - Update
AGENTS.mdto add the domain under "Context Files by Task"
Rules
- Follow existing domain structure (see
.context/auth/or.context/api/as examples) - Use project-specific content, not generic best practices
- Include decision rationale in every section
- Keep files under 200 lines each
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.

new-domain is a skill published in the GitHub repository andrefigueira/.context (253 stars, last pushed 4mo ago), licensed MIT. It adds 32 tokens to every session and 293 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 2026-08-30.
