What it does
Person Timeline is an agent skill from LC044/TrailSnap. 按年份和事件整理指定人物出现过的照片，展示共同经历、成长变化、地点与同行人，并可生成可追溯的人物故事。
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: TrailSnap (行影集) | AI-Powered open-source photo album for travel & life memories.（AI赋能的开源相册工具，珍藏旅行与生活点滴）. The licence is AGPL-3.0.
Example prompts
- “/person-timeline”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- 用户必须先指定一个人物。优先使用页面提示中提供的 identity_id；只有姓名时先调用人物查询工具确认唯一人物，不要猜测重名人物。
- 调用 get_person_timeline 获取跨年份分布、连续事件、地点、同行人和代表照片。默认先给出全局概览，不要一开始展开所有照片。
- 先展示照片数量、时间跨度、各年份分布和最多 5 个代表事件。若返回 photos_truncated=true，必须说明概览基于受限样本，并请用户缩小日期范围后再次查询。
- 用户关注某一年或某个事件时，用该事件的代表 photo_id 调用 view_photos 或 create_contact_sheet，再用 get_photo_context 核对最多 30 张照片。
- 人脸识别只证明该人物被归入照片，地点和拍摄时间来自元数据。不得仅凭同框、出现频率或画面内容推断亲属、恋爱、职业、健康或其他敏感关系。
- 描述成长和变化时使用可观察事实，例如年份、场景、服饰或活动；对年龄、情绪和人物关系使用“可能”并明确它属于视觉推测。
- 用户明确要求保存后，才调用 select_representative_photos，再用 create_artifact_draft(artifact_type="person_story") 生成结构化人物故事；需要个性展示时再生成 HTML。每个段落保留来源照片 ID。
- 整个浏览和分析过程只读，不修改人物身份、人脸归属或照片。展示图片时原样使用工具返回的 thumbnail_url。
What it can do on your machine
Read from SKILL.md and the folder at commit 9d4b63e. 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
Person Timeline loads about 200 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 38 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); files beside SKILL.md are not scanned.

To copy it by hand, put the folder in .cursor/skills/person-timeline, .gemini/skills/person-timeline, .github/skills/person-timeline and .opencode/skills/person-timeline in your project.
What does Person Timeline need to run?
SKILL.md names no scripts, command-line tools or credentials: Person Timeline is instructions for the agent only.
