Knowledge comics (知识漫画): educational, biography, tutorial.

Skill metadata

Reference: full SKILL.md

The following is the complete skill definition that Mibyan loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.

Knowledge Comic Creator

Adapted from baoyu-comic for Mibyan’s tool ecosystem. Create original knowledge comics with flexible art style × tone combinations.

When to Use

Trigger this skill when the user asks to create a knowledge/educational comic, biography comic, tutorial comic, or uses terms like “知识漫画”, “教育漫画”, or “Logicomix-style”. The user provides content (text, file path, URL, or topic) and optionally specifies art style, tone, layout, aspect ratio, or language.

Reference Images

Mibyan’ image_generate tool is prompt-only — it accepts a text prompt and an aspect ratio, and returns an image URL. It does NOT accept reference images. When the user supplies a reference image, use it to extract traits in text that get embedded in every page prompt: Intake: Accept file paths when the user provides them (or pastes images in conversation).
  • File path(s) → copy to refs/NN-ref-{slug}.{ext} alongside the comic output for provenance
  • Pasted image with no path → ask the user for the path via clarify, or extract style traits verbally as a text fallback
  • No reference → skip this section
Usage modes (per reference): Record in each page’s prompt frontmatter when refs exist:
Character consistency is driven by text descriptions in characters/characters.md (written in Step 3) that get embedded inline in every page prompt (Step 5). The optional PNG character sheet generated in Step 7.1 is a human-facing review artifact, not an input to image_generate.

Art, Tone & Preset Catalogue

  • Art styles (6): ligne-claire, manga, realistic, ink-brush, chalk, minimalist. Full definitions at references/art-styles/<style>.md.
  • Tones (7): neutral, warm, dramatic, romantic, energetic, vintage, action. Full definitions at references/tones/<tone>.md.
  • Presets (5) with special rules beyond plain art+tone: Full rules at references/presets/<preset>.md — load the file when a preset is picked.
  • Compatibility matrix and content-signal → preset table live in references/auto-selection.md. Read it before recommending combinations in Step 2.

File Structure

Output directory: comic/{topic-slug}/
  • Slug: 2-4 words kebab-case from topic (e.g., alan-turing-bio)
  • Conflict: append timestamp (e.g., turing-story-20260118-143052)
Contents:

Language Handling

Detection Priority:
  1. User-specified language (explicit option)
  2. User’s conversation language
  3. Source content language
Rule: Use user’s input language for ALL interactions:
  • Storyboard outlines and scene descriptions
  • Image generation prompts
  • User selection options and confirmations
  • Progress updates, questions, errors, summaries
Technical terms remain in English.

Step Summary

User Questions

Use the clarify tool to confirm options. Put independent questions in one questions array (up to 5); ask separately any question whose options depend on an earlier answer. See references/workflow.md for the full Step 2 question set. Timeout handling (CRITICAL): clarify can return "outcome": "timed_out" with responses marked "status": "unanswered" — this is NOT user consent to default everything.
  • Treat it as a default for the unanswered questions only. Each question is an independent consent point.
  • Surface the default to the user visibly in your next message so they have a chance to correct it: e.g. "Style: defaulted to ohmsha preset (clarify timed out). Say the word to switch." — an unreported default is indistinguishable from never having asked.
  • Do NOT collapse Step 2 into a single “use all defaults” pass after one timeout. If the user is genuinely absent, they will be equally absent for all five questions — but they can correct visible defaults when they return, and cannot correct invisible ones.

Step 7: Image Generation

Use Mibyan’ built-in image_generate tool for all image rendering. Its schema accepts only prompt and aspect_ratio (landscape | portrait | square); it returns a URL, not a local file. Every generated page or character sheet must therefore be downloaded to the output directory. Prompt file requirement (hard): write each image’s full, final prompt to a standalone file under prompts/ (naming: NN-{type}-[slug].md) BEFORE calling image_generate. The prompt file is the reproducibility record. Aspect ratio mapping — the storyboard’s aspect_ratio field maps to image_generate’s format as follows: Download step — after every image_generate call:
  1. Read the URL from the tool result
  2. Fetch the image bytes using an absolute output path, e.g. curl -fsSL "<url>" -o /abs/path/to/comic/<slug>/NN-page-<slug>.png
  3. Verify the file exists and is non-empty at that exact path before proceeding to the next page
Never rely on shell CWD persistence for -o paths. The terminal tool’s persistent-shell CWD can change between batches (session expiry, TERMINAL_LIFETIME_SECONDS, a failed cd that leaves you in the wrong directory). curl -o relative/path.png is a silent footgun: if CWD has drifted, the file lands somewhere else with no error. Always pass a fully-qualified absolute path to -o, or pass workdir=<abs path> to the terminal tool. Incident Apr 2026: pages 06-09 of a 10-page comic landed at the repo root instead of comic/<slug>/ because batch 3 inherited a stale CWD from batch 2 and curl -o 06-page-skills.png wrote to the wrong directory. The agent then spent several turns claiming the files existed where they didn’t. 7.1 Character sheet — generate it (to characters/characters.png, aspect landscape) when the comic is multi-page with recurring characters. Skip for simple presets (e.g., four-panel minimalist) or single-page comics. The prompt file at characters/characters.md must exist before invoking image_generate. The rendered PNG is a human-facing review artifact (so the user can visually verify character design) and a reference for later regenerations or manual prompt edits — it does not drive Step 7.2. Page prompts are already written in Step 5 from the text descriptions in characters/characters.md; image_generate cannot accept images as visual input. 7.2 Pages — each page’s prompt MUST already be at prompts/NN-{cover|page}-[slug].md before invoking image_generate. Because image_generate is prompt-only, character consistency is enforced by embedding character descriptions (sourced from characters/characters.md) inline in every page prompt during Step 5. The embedding is done uniformly whether or not a PNG sheet is produced in 7.1; the PNG is only a review/regeneration aid. Backup rule: existing prompts/…md and …png files → rename with -backup-YYYYMMDD-HHMMSS suffix before regenerating.

Page Modification

IMPORTANT: When updating pages, ALWAYS update the prompt file (prompts/NN-{cover|page}-[slug].md) FIRST before regenerating. This ensures changes are documented and reproducible.

Pitfalls

  • Image generation: 10-30 seconds per page; auto-retry once on failure
  • Always download the URL returned by image_generate to a local PNG — downstream tooling (and the user’s review) expects files in the output directory, not ephemeral URLs
  • Use absolute paths for curl -o — never rely on persistent-shell CWD across batches. Silent footgun: files land in the wrong directory and subsequent ls on the intended path shows nothing. See Step 7 “Download step”.
  • Use stylized alternatives for sensitive public figures
  • Step 2 confirmation required - do not skip
  • Steps 4/6 conditional - only if user requested in Step 2
  • Step 7.1 character sheet - recommended for multi-page comics, optional for simple presets. The PNG is a review/regeneration aid; page prompts (written in Step 5) use the text descriptions in characters/characters.md, not the PNG. image_generate does not accept images as visual input
  • Strip secrets — scan source content for API keys, tokens, or credentials before writing any output file
