tech-diagram-gif

tech-diagram-gif is a skill for Claude Code from kopp0510/claude-dd. It costs 89 tokens per session (5,128 once invoked), scanned A, original, MIT.

A diagram-making workflow that turns confirmed process, architecture, and data-flow descriptions into animated, looping GIFs. It uses SVG as an intermediate format and checks the rendered result before delivery.

In plain words
What is it for?
Use it to show system architecture, workflows, network or data flows, event-stream layouts, and similar technical diagrams as animations.
Why use it?
It prevents the diagram from being based on guessed structure and catches rendering problems before the GIF is delivered.

Token cost

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.

Security

Grade A, and why

tech-diagram-gif 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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/test-verify-geometry.py, scripts/verify-geometry.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Tech Diagram GIF — 技術圖表繪製與 GIF 匯出

不引入 Python/cairosvg 渲染管線的技術圖表流程:手寫 SVG(依 vendored 風格規範)→ 瀏覽器渲染自檢 → 匯出無縫循環 GIF。 渲染與匯出全程靠瀏覽器與 ffmpeg,不裝 cairosvg / Pillow 等套件;scripts/verify-geometry.py 是唯一的 Python,純標準庫、無 pip 依賴,只做座標算術,缺 python3 時退化為人工計算,不阻擋出圖。 風格規範 vendored 自 fireworks-tech-graph(MIT,見 LICENSE.txt); 只收編其 markdown 規範,不引入其 Python/cairosvg/FFmpeg 管線。

硬閘門

  1. 先判斷該不該畫 — 動筆前問一句:讀者從這張圖學到的,會比從一段文字或一張表格多嗎? 不會就別畫,直接寫清楚。純清單、簡單前後對照、單一形狀的「圖」一律退回文字。 使用者明確指定要圖時跳過此閘門,但仍可提一句更省的做法(提一次,不反覆)。
  2. 結構未確認前,不寫任何 SVG — 先用純文字把節點/分組/連線定案(工作流程第 1 步)。
  3. 交付物只有 GIF(使用者硬規則)。SVG 僅為中間產物:GIF 產出並驗證後即刪除, 不留在交付目錄。唯一例外:環境無 ffmpeg 時依第 5 步退化交付 SVG 並附裝法與資安說明 (SVG 格式可含 script,收件方有信任成本;本 skill 產的 SVG 零 script,交付前必驗證)。
  4. 渲染自檢不可省 — 沒親眼看過渲染結果不得宣稱完成。

工作流程

1. 結構確認(純文字,不畫圖)

把要畫的內容整理成清單給使用者確認,格式:

節點(N):① 名稱(語意桶)→ ② …
分組(M):分組名 / 涵蓋節點
連線與語意:A→B 主流程(金)/ C⇢D 條件檢查(虛線)/ 自迴圈…

清單交出去前先過下方 Taste Gate 的「結構清單」組 —— 數量上限在這一步就數得出來 (節點/連線/分組三個數字見該組,本節不複製),此時超標只要改清單; 等到第 4 步才發現,只能整份重來。 使用者確認或修改 → 定案才進下一步。內容事實(節點名稱、流程順序)不確定時回問,不自行腦補。

2. 選風格與動畫模式

風格 檔案 何時用
Style 8 Dark Luxury(預設) references/style-8-dark-luxury.md 架構、流程、資料流、拓撲 — 通用首選
Style 2 Dark Terminal references/style-2-dark-terminal.md 開發者風格;UML 類(ER/時序/狀態機/use case)優先用此 — Style 8 深底吃 UML 細節與人形,比較表也不適合
Style 11 Event Transit references/style-11-event-transit.md 事件流/串流拓撲(Kafka/Pulsar/NATS、消費者群、DLQ)— 提到「事件流」「地鐵圖」「Kafka 拓撲」時用
Style 12 Ops Pulse references/style-12-ops-pulse.md 事故排查/SLO review(golden signals、critical path、trace 瀑布)— 提到「事故圖」「golden signals」「reliability」時用

動畫兩種模式(詳見 references/motion-narrative.md):

  • 循環流動(預設):小球沿線跑(animateMotion)或 dash 脈衝
  • 建置 → 營運(敘事):開場無連線 → 逐條畫入 → 營運流動 → 淡出循環 — 對外展示/README hero 用

使用者無明示偏好時用預設,不必多問;圖型落在特定風格的甜蜜區時主動建議換風格(一句話,不反覆)。

3. 手寫 SVG

  • 版面規則照 references/svg-layout-best-practices.md(間距 ≥80px、正交轉角、標籤偏移、z-order; 該檔僅取版面規則,其 cairosvg/PNG 匯出段落不適用本 skill)
  • 節點複雜或含 DB/佇列/使用者/決策時,用 references/icons.md 的語意圖形 (DB 圓柱、佇列管、LLM 雙框、Agent 六角形、User 人形、決策菱形、文件摺角)取代一律圓角矩形
  • 量化預算三組 —— showcase profile 表(交叉/折數/繞路比/間距)、「元素數量預算」、 「連線可量測規則」—— 數字全在 references/composition-quality-contract.md,本節不複製。 撰寫時開那張表照著寫,操作用的逐項版本見下方 Taste Gate;兩處不符一律以 contract 為準。 超出 → 調節點位置,或拆成總覽 + 細節兩張;不縮字級、不壓間距硬塞
  • 節點間距 80px vs 40px、標籤三個間隙數字各量什麼 —— 裁決與說明見 contract 「與上表衝突時取嚴」節,不要自行挑一個用
  • 節點、容器、連線、標籤遮罩一律加 data-rolenode / container / edge / mask) —— scripts/verify-geometry.py 優先讀這個標記;沒有標記時它會退化用畫法猜並印警告, 猜錯就是靜默漏檢(實測踩過:矩形節點被當成菱形而誤報溢出;漸層畫布讓兩項遮罩檢查 一起空轉卻印「全部通過」)
  • 版面順序與走廊:先排容器與列才排線、保留跨層走廊、legend 不進流程走廊
  • 色票/節點語意色桶照所選風格檔;畫布建議 viewBox 0 0 1440 1080注意風格檔的字級/間距以 960 寬為基準,用 1440 畫布時需等比放大(約 ×1.5)
  • 字體堆疊必含跨平台 CJK 後備(以本段為準,覆蓋風格檔的 PingFang SC): 襯線 Georgia,'Times New Roman','Songti TC','Noto Serif CJK TC',serif、 無襯線 -apple-system,'Helvetica Neue','PingFang TC','Noto Sans CJK TC',sans-serif (macOS 已驗證;Linux 走 Noto 後備,未實測)
  • 小球規則:核心 r4 + 光暈 r8 opacity 0.22、顏色跟隨箭頭語意、等速(dur ∝ 路徑長)、 長路徑放 2 顆錯開半週期
  • 所有動畫 dur 與 begin 必須整除同一個總循環長(如 7.2s)— GIF 才能無縫循環
  • dash 脈衝模式:實線疊亮色 stroke-dasharray: 7 41stroke-dashoffset;位移量須為 dasharray 週期整數倍
