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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
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 | $0.00088 | $0.00758 |
| Opus 5.5 | $0.00035 | $0.00303 |
| Sonnet 5.5 | $0.00018 | $0.00152 |
| Haiku 4.5 | $0.00009 | $0.00076 |
Grade A, and why
create-canvas 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
投研画布（备选交付）
何时使用
用户明确点名要一份可预览的画布 / 一页式机构风图文报告（对比表、多章节 TSX 排版）。
默认投研交付是网页（@skill:create-web / create_web）。未点名画布时，投研技能应优先 create_web，不要主动改用本技能。
与网页 / 围栏的区别
| 形态 | 何时用 |
|---|---|
create_web（默认） |
投研 HTML 报告页、离线交互页 |
create_canvas（本技能） |
用户点名画布 / 一页式机构报告 |
| 正文 chart 围栏 | 日常定量小插图，无需 artifacts |
「画个柱状图」→ 优先围栏；「出一份画布报告」→ 本技能。
步骤
- 确认交付形态：用户已点名画布/一页式机构报告；否则转
create_web。 - 取数：用已有行情/基本面/资讯等工具；缺失写明，禁止编造。
- 创建画布：
create_canvas写入 TSXsource。仅允许import … from 'react'与import { … } from '@opptrix/canvas'；用Surface/Stack/H1–H3/Text/Stat/Table/Chart/Callout/Quote等 curated 组件。 - 版式：机构调研报告风格——H1 → 导语 → H2 分章；定量优先
Chart；须有说明文字。 - 更新：已有画布先
read_canvas，再update_canvas。 - 输出边界：事实与推断分开；不给出买卖建议。
禁止
- 外网 CDN、任意第三方 npm/脚本（含直接
import echarts） - 荐股、编造数据
- 用
workspace_write代替create_canvas - 把未点名画布的投研流程默认做成画布（应优先
create_web）
与网页技能分工

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.

create-canvas is a skill published in the GitHub repository Travisun/Opptrix (275 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 88 tokens to every session and 758 once invoked, about $0.0004 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 2026-08-30.
