What it does

Form Filling is an agent skill from asgeirtj/system_prompts_leaks. Fill out online forms (Google Forms, Typeform and similar) or PDF, Word and DocuSign forms; prepare a reviewable draft and get approval before submitting or sending.

Its SKILL.md is about 400 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 Documents & Office, covering Forms and invoices. The repository describes itself as: Documented system prompts from Anthropic - Claude Fable 5.1, Opus 5.5, Claude Design, Claude Code. OpenAI - ChatGPT GPT-6-Astra, Codex. Google - Gemini 3.8 Flash, 3.1 Pro… The licence is CC0-1.0.

When your agent uses it

  • Tasks that involve Forms and invoices

Example prompts

  • “/form-filling”

What it can do on your machine

Read from SKILL.md and the folder at commit 60d44cc. 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

Form Filling loads about 400 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 223 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~400

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.

Fill out online forms (Google Forms, Typeform and similar) or PDF, Word and DocuSign forms; prepare a reviewable draft and get approval before submitting or sending.

Form filling

  • Read the whole form. Find answers in the conversation, files and relevant connected sources before asking. You can find information in past emails, attachments, receipts, relevant google drive and local files, and many other sources. For example, if you're looking for the user's full name for a flight look at previous flight emails, if you're filling out a bank form look for previous official forms from places like banks and government agencies.
  • Fill what you know; look for answers for what you don't know and if you can't find it make reasonable, low-risk guesses when useful and flag them for the user. Leave genuinely unknown fields blank; bundle questions for required unknowns or decisions only the user can make. Never guess consent, signatures or personal attestations.
  • Prepare and check the filled draft. If typing or advancing would share answers with the recipient, work in a private copy first. Link to the filled draft; if the service has no private draft link, provide a private, user-accessible copy of the completed answers.
  • Before submitting or sending externally, give a short approval summary: what was filled, who will receive it, any guesses or inferred context you could not verify, and anything missing or requiring the user's decision. Offer to submit and wait for explicit approval; then submit only as approved and verify the outcome.
