What it does

Source Connector Authoring is an agent skill from Bubble252/offer-harvester. Design and validate safe source connector manifests for public graduate-admission, policy, advisor, lab, and community sources. Use when adding a crawler, refresh job, source connector, source access policy, field mapping, live test, or safe fallback.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/manifest-schema.md` and `scripts/manifest_fixture.json`).

It sits in Data & Analytics, covering Web scraping. The licence is MIT.

When your agent uses it

  • Adding a crawler
  • Source connector
  • Source access policy

Example prompts

  • “/source-connector-authoring”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read references/manifest-schema.md before creating or editing a connector.
  2. Define a source-specific allowlist, field mapping, refresh interval, rate limit, and fallback.
  3. Record robots/ToS review date and allowed access method.
  4. Use public pages, official APIs, or explicitly authorized exports only.
  5. Validate the manifest with scripts/validate_manifest.py --input .

What it can do on your machine

Read from SKILL.md and the folder at commit c640922. 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 2 files in scripts/ (Python), which the agent can run.

    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

Source Connector Authoring loads about 379 tokens when it runs, and up to ~514 if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 151 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~379
With references · SKILL.md plus every file in references/, read only if the agent opens them
~514

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.

description
Design and validate safe source connector manifests for public graduate-admission, policy, advisor, lab, and community sources. Use when adding a crawler, refresh job, source connector, source access policy, field mapping, live test, or safe fallback.

Source Connector Authoring

  1. Read references/manifest-schema.md before creating or editing a connector.
  2. Define a source-specific allowlist, field mapping, refresh interval, rate limit, and fallback.
  3. Record robots/ToS review date and allowed access method.
  4. Use public pages, official APIs, or explicitly authorized exports only.
  5. Validate the manifest with scripts/validate_manifest.py --input <manifest.json>.

Hard Boundaries

  • Do not bypass login walls, CAPTCHA, private-group access, robots controls, or rate limits.
  • Do not treat a community post as confirmed fact; emit it only as a reviewable risk signal.
  • Do not store full community content unless its source policy allows it and a deletion path exists.
  • Do not register a connector until its live test and human policy review pass.

中文说明

  1. 创建或编辑 connector 前先阅读 references/manifest-schema.md。
  2. 定义来源专属 allowlist、字段映射、刷新间隔、限速与失败 fallback。
  3. 记录 robots/ToS 审查日期和允许的访问方式。
  4. 只使用公开页面、官方 API 或明确授权的导出。
  5. 使用 scripts/validate_manifest.py --input <manifest.json> 校验 manifest。
强制边界
  • 不绕过登录墙、CAPTCHA、私密群组权限、robots 控制或限速。
  • 社区帖子不是确认事实，只能输出为待复核风险信号。
  • 除非来源策略允许且有删除路径，否则不保存完整社区正文。
  • connector 通过 live test 和人工策略审查前不得注册。
