What it does
The SKILL.md is written in Chinese. A bundled Python script scans the workspace, Git history, local main and origin/main for the newest release-notes Markdown without switching branches or fetching anything, and the agent reads the notes, their source and any @GitHubID mentions from the result. It picks the main features and key fixes only from what the notes say, leaves the features or fixes list empty when a release has none, and keeps every claim traceable to the original text.
Contributors with a clear credit in the notes are checked against GitHub's public user API and their real avatars are downloaded; if an ID cannot be verified, the run stops and reports it instead of inventing or redrawing an avatar. A second script step renders the poster from a `poster-spec.json` file into a PNG with accurate Chinese text, with no image-generation model drawing the body. The agent also writes `wechat-copy.txt`: the version number, one sentence on the main change and one sentence of thanks. Nothing is sent to a group automatically, and creating or publishing the GitHub Release is out of scope.
Generated files go under the git-ignored `artifacts/` folder. Scanning needs only the Python standard library, while rendering needs Pillow and a system font that covers Chinese.
When your agent uses it
- Announcing a new version to a WeChat group with a poster and a short message
- Crediting release contributors with verified GitHub IDs and real avatars
- Regenerating the poster for an earlier version of the release notes
Example prompts
- “Use release-announcement to make the WeChat poster and short message for the latest version.”
- “Generate the release poster for version 0.6.6 and keep it separate from the newest one.”
- “Check the contributor IDs in the latest release notes and put their avatars on the poster.”
Requirements
- Python for the scan and render scripts
- Pillow and a Chinese-capable system font for rendering
- Network access to GitHub's public user API for avatars

What it can do on your machine
Read from SKILL.md and the folder at commit 1c78154. 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
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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
Release Announcement Poster loads about 516 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 124 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.

Release announcement
在本仓库调用 $release-announcement 时，交付一张可发微信群的 PNG 长图和一段很短的群文案。默认使用 版式与文案要求；用户另有要求时以用户要求为准。
调用方式：Codex 使用 $release-announcement；Claude Code Haha 的终端输入 /release-announcement。这两个工具都从项目的 .agents/skills/ 读取同一份技能。
工作流
- 在仓库根目录运行
python3 .agents/skills/release-announcement/scripts/release_poster.py scan --repo . --out artifacts/release-posters/latest-scan.json。它按语义版本比较工作区、当前 Git 历史、本地main和已有的origin/main，不切换分支、不抓取远程。读取 JSON 中的中文发布说明、来源和@GitHubID提及；credit_candidate仅表示有明确署名格式，仍需核对上下文。如果来源不是工作区文件，明确告知用户。 复测旧版本时加--version 0.6.6并使用独立输出路径，避免覆盖最新版本的 scan 结果。 - 仅依据该版本的中文 release note 提炼主要功能和关键修复；纯修复版的
features留空，纯功能版的fixes留空，绝不为了填版式虚构内容。有重要模型或供应商更新时可加一个简短区块。每条信息必须能追溯到原文，压缩表述时保留条件和边界。安装提醒只写原文确有的信息。不要把英文译文重复计数。 - 对
credit_candidate: true的账号逐个核对发布说明里的贡献项；普通@ID提及（例如 PR reviewer）不算代码署名。render会通过 GitHub 公共用户 API 校验 ID 并下载真实头像；无法核验时停止并报告，不能臆造头像、错配姓名，不能让图像生成模型重绘头像。正式生成不能使用avatar_path跳过核验。 - 按 数据格式 写
poster-spec.json，版本必须与 scan 结果一致。运行python3 .agents/skills/release-announcement/scripts/release_poster.py render --scan artifacts/release-posters/latest-scan.json --spec <poster-spec.json> --out <poster.png>。建议输出到artifacts/release-posters/v<version>/，保留已有文件，文件名加版本或修订号。此脚本固定使用紧凑版式绘制准确中文和头像；不要用 imagegen 绘制正文。 - 写一段适合微信群的短文案，保存为同目录的
wechat-copy.txt：版本号 + 1 句主要变化 + 1 句感谢，具体细节交给图片。有本次明确署名的贡献者时感谢代码贡献；没有时只感谢反馈与支持，不暗示本版有特定群友提交。文案不要宣称未核实的下载地址或公开发布状态，也不要自动向群发送。若需要下载入口，先检查对应 GitHub Release 是否存在。 - 打开成图检查标题、文字换行、头像和 ID 对应、正文是否从顶部很快开始。最后提供 PNG、短文案、所用 release note 来源和任何未核实项。生成物放在被 Git 忽略的
artifacts/，不要提交生成图、头像缓存或中间 JSON。
图像与环境
默认长图不需要生成式插画：顶部仅有约 230px 的版本标题，直接进入实际有内容的功能或修复区。这样版式与中文文字最稳定。用户明确想增加插画时，可用 imagegen 只生成无字装饰素材，再用脚本绘制全部文字与真实头像；不能让装饰占去首屏。
scan 只用 Python 标准库；render 需要 Pillow 和可用的中文系统字体。缺依赖时先查看项目已有运行环境，不为一次制图修改生产依赖。GitHub 头像获取是公开只读请求；失败时给出具体账号和原因。
