What it does

Tdn Lookup is an agent skill from thalysjuvenal/advpl-specialist. Use as the escalation strategy when local ADVPL/TLPP reference material lacks an answer -- a tiered approach (local cache first, then TDN Confluence REST API via WebFetch, then Playwright against the API, then WebSearch, then visual site search) for looking up native functions, entry points, unknown errors, or business processes on TDN (tdn.totvs.com). Also triggers on Portuguese phrasing like "buscar documentacao no TDN", "nao encontrei na referencia local", "pesquisar funcao no TDN", "documentacao oficial…

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Backend & APIs, covering Search implementation, REST APIs and Browser testing. It works with Playwright and Confluence. The repository describes itself as: Plugin para Claude Code especializado em ADVPL e TLPP para desenvolvimento TOTVS Protheus. The licence is MIT.

When your agent uses it

  • Portuguese phrasing like buscar documentacao no TDN
  • Nao encontrei na referencia local
  • Pesquisar funcao no TDN
  • Documentacao oficial TOTVS

Example prompts

  • “buscar documentacao no TDN”
  • “nao encontrei na referencia local”
  • “pesquisar funcao no TDN”
  • “/tdn-lookup”

What it can do on your machine

Read from SKILL.md and the folder at commit d80599b. 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

Tdn Lookup loads about 508 tokens when it runs. Until then it costs about 142 tokens; SKILL.md has 200 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~142
When it runs · the whole SKILL.md, loaded when a task matches
~508

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.

TDN Lookup — Online Search Strategy

This skill defines the standardized fallback strategy for finding official TOTVS documentation on TDN (tdn.totvs.com, a public Confluence Data Center 7.19 site with an unauthenticated REST API) whenever local reference material is insufficient. It specifies a five-tier escalation: Tier 1 always checks the relevant local cache file first (native functions, SX dictionary, common errors, entry points, business modules); Tier 2 queries the Confluence REST search API directly via WebFetch with a CQL query; Tier 3 falls back to Playwright hitting the same API when WebFetch is blocked; Tier 4 uses WebSearch plus Playwright navigation when CQL search yields nothing; Tier 5 is a last-resort manual/visual search on the TDN site itself.

Activate this skill whenever a native function, entry point, error code, or business process is not found (or only partially found) in the local reference files, or whenever the user explicitly asks for official TOTVS documentation. It does not itself contain domain knowledge -- it only orchestrates the search process; the actual native function, entry point, and error catalogs live in protheus-reference, advpl-code-generation, advpl-debugging, and protheus-business.
