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 | $0.00304 | $0.00304 |
| Opus 5.5 | $0.00122 | $0.00122 |
| Sonnet 5.5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
cursor-session-init 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 2mo 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
loom 会话初始化
每次开始工作前，必须先执行以下检查，再响应用户请求：
- 检查
.loom/目录是否存在。若不存在，提示用户运行/loom-init-project，然后停止。 - 读取
.loom/workflow.yaml了解当前项目的流水线配置。 - 渐进式加载上下文文件（避免整文件读取挤爆上下文）：
.loom/rules/constitution.md：先用loom_get_context(doc="constitution")取目录，按需取节。.loom/memory/MEMORY.md：先用loom_get_context(doc="memory")取目录。.loom/rules/product.md：若存在，仅读取关键章节。
- 渐进式加载技能文件：用
loom_get_skill_context()获取所有技能的 L0 摘要，仅当需要执行某技能时用loom_get_skill_context(skill="技能名")获取完整内容。禁止一次加载所有 SKILL.md 全文。 - 检查
specs/目录下是否有进行中的开发任务（有 spec.md 但无 verify-report.md 的目录），若有，列出当前阶段。
完成以上检查后，简要输出状态，然后响应用户请求。
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.

cursor-session-init is a cursor rule published in the GitHub repository xiqin/loom (6 stars, last pushed 14d ago), licensed MIT. It adds 304 tokens to every session, about $0.0012 per session on Opus 5.5. 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.
