Turn product facts and a loose image brief into a complete, editable image prompt with clear constraints.

  • The user wants prompt writing
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Revision rather than image generation

What it does

Product Prompt Brief is an agent skill from T8mars/T8-penguin-canvas. Turn product facts and a loose image brief into a complete, editable image prompt with clear constraints. Use when the user wants prompt writing or revision rather than image generation.

Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Image generation. The licence is MIT.

When your agent uses it

  • The user wants prompt writing
  • Revision rather than image generation

Example prompts

  • “/product-prompt-brief”

What it can do on your machine

Read from SKILL.md and the folder at commit 4e8175b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Product Prompt Brief loads about 229 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 12 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~229

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

商品提示词整理 / Product prompt brief

把用户零散的商品信息、参考图说明和创作要求整理成可直接使用的完整提示词。纯文字资料也可以完成,不强迫用户上传图。用用户的语言写作,保持品牌语气;不擅自扩展成营销方案、多镜头广告或实际媒体生成。

优先保留用户明确的信息:主体是什么、谁会看、在哪里使用、必须保留什么、允许改变什么。区分已知事实与创意设定,不补写价格、功效、认证、模糊图片上的品牌字或不存在的卖点。仅当关键信息缺失到无法写出有意义提示词时,问一个最重要的问题;其余使用说明清楚的合理默认。

完整作品包含两部分:

  • 可复制的提示词正文:自然连贯地说明主体身份与保留项、主体和环境的关系、构图/留白、光线/材质、用户明确指定的文字及比例。信息必须自足,不写“同上”“见之前那条”。
  • 简短核对项:最多三个对这份要求真正重要的检查点;标明任何尚待用户确认的事实。不要把内部 ID、模型配置、检查记录塞进提示词正文。

用户提供了原稿时,先保留有效部分,再解决冲突、歧义或多余形容词。用户要求“只改背景”“缩短但保留中文文案”等限定修改时,其他事实和指定文字原样保留。若缩短会破坏必要信息,指出取舍而不是悄悄删掉。

长正文放入完整文本作品,聊天只说明改进点并提供后续修改方向。交付提示词不等于完成图片;此技能不发起图片、视频、上传或额外评审调用。用户改为想要成图时,说明可以切换到图片创作方法,保留现有提示词供用户使用,不擅自替换任务。
