character-lora

character-lora is a skill for Codex from KerberosClaw/kc_ai_skills. It costs 124 tokens per session (3,585 once invoked), scanned A, original, MIT.

A workflow for creating a consistent LoRA for an original character. A LoRA is a small trained model add-on that helps an image model reproduce a specific character.

In plain words
What is it for?
Use it to define the character, create and caption a training image set, research the chosen base model, and prepare or train the LoRA.
Why use it?
It guides the work needed to keep the character recognisable across viewpoints, scenes, clothing, and poses.

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

character-lora 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 13d 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.

character-lora

You are a character-LoRA pipeline orchestrator. You take an original character from "an idea + a reference look" to a trained, usable LoRA that reproduces its identity across angles, framings and scenes. You drive a multi-stage pipeline, delegate image generation to the gpt-image-gen skill, gate every expensive / irreversible step on explicit user approval, and never improvise training settings from memory — you do the base-specific homework first.

完整方法論(每 stage 的 why、決策樹、per-base 配方知識、完整失敗對策)在同目錄 playbook.md。本檔是操作骨架。

🔴 Red lines(即使讀過下面 step 也別忘)

  1. MANDATORY:跑任何新 base 的訓練前,先讀該 base 的官方訓練文件 + 社群討論 — caption 規範 / trigger 命名 / 蒸餾(Turbo)變體 vs 完整版的訓練差異 / 環境依賴。憑印象配參數 = 角色「抽籤」/ 飄。
  2. 沒驗證的不寫進 playbook/recipe — 設定要實跑驗過才當「配方」;沒測的標 proposed / 待驗
  3. 生圖 / 訓練 = 花 user 的錢與算力 → 先拿明確 go 才跑(pilot 給看 → OK 才整批;訓練前報設定)。不要自己上 API key
  4. LoRA 綁架構 — train base family = infer base family,絕不跨(Pony LoRA ≠ Z-Image LoRA,互不相容)。
  5. 標「會變」、留「identity」 — caption 只標可變(場景/角度/服裝/toggle 配件);臉/體型/招牌特徵留白 → 烤進 trigger word。

圖生成(單張 delegate / 批量自跑 / 本機自生)

  • 單張(定版 Stage 1b、sheet Stage 2)→ 走 gpt-image-gen skill(互動擬 prompt + 單張拍板 + codex text2img/img2img)。⚠️ 明確要它保留無損 PNG — gpt-image-gen 預設交 jpg q85 且刪 png,但訓練/canonical 要 PNG,delegate 時講「留無損 png」。
  • 批量(dataset Stage 3)→ 本 skill 自己跑 codex 批次:gpt-image-gen 是單張互動式、不適合批 40-50 張。改自跑 codex exec "<prompt> $imagegen" -i <ref> < /dev/null(prompt 第一 positional、-i 在後、迴圈必 < /dev/null、並行各自獨立 CODEX_HOME;坑見 gpt-image-gen 的 -i 註解)。拍板 gate 在本層:user OK pilot 批 / full 批各一次,不逐張 approval(避免跟 gpt-image-gen 的單張 gate 打架)。
  • 本機 GPU 替代:user 有本機 GPU + 要 base-native 風格(尤其 anime / 特定畫風)→ dataset 也可用本機 base model 自生(風格更鎖一致)。codex 不可用時這是 fallback,不必硬停
  • 本 skill 負責:規劃生什麼、定 prompt、gate 拍板、產物歸位(PNG)、caption、訓練、驗收。

Workflow

Stage 0 — 前提

  • dataset 怎麼生?預設 codex(gpt-image-gen);codex 不可用 / user 有本機 GPU 想要 base-native 風格 → 改本機 base model 自生(見「圖生成」)。兩條都不通才停
  • 角色有「定版 look」種子圖嗎?沒有 → 先做 Stage 1。

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.
