What it does

Datasheets is an agent skill from biosshot/easyeda-copilot. Download component datasheet PDFs, locate useful pages, and read verified pinouts, electrical limits, thermal data and application notes using the agent's PDF tools. Use for schematic creation or review, unfamiliar components, substitutions, and component-specific layout requirements.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/reading.md`).

It sits in Documents & Office, covering PDF. It works with EasyEDA, Model Context Protocol and Vue.js. The repository describes itself as: AI-powered assistant for EasyEDA — generate schematics from natural language, browse LCSC components, design PCBs with custom DRC configurations, and get interactive circuit… The licence is MIT.

When your agent uses it

  • Schematic creation
  • Unfamiliar components
  • Component-specific layout requirements

Example prompts

  • “/datasheets”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 18b97c2. 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/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node

    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

Datasheets loads about 1.2k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 617 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

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
Download component datasheet PDFs, locate useful pages, and read verified pinouts, electrical limits, thermal data and application notes using the agent's PDF tools. Use for schematic creation or review, unfamiliar components, substitutions, and component-specific layout requirements.

DataSheets

Standalone Node.js >=20.19 scripts; no Python, npm packages, EDA connection or LLM API required. Resolve scripts relative to this SKILL.md. PDF reading and engineering interpretation belong to the calling agent. Optional text navigation uses an existing Poppler pdftotext; missing Poppler never invalidates a successful download.

Workflow

  1. Identify the question, exact component and package. Reuse a local PDF when already available. Obtain a URL from the caller's component search (for EasyEDA, component_search returns datasheet), supplied URL, or manufacturer documentation. Do not repeat a component search whose result is already available.
  2. Run node scripts/download.mjs "URL" --out ./datasheets/MPN.pdf. It follows HTTP redirects and supported explicit PDF links/refreshes in wrapper pages, rejects obvious non-PDF/incomplete responses, and returns the absolute path, source/final URLs, SHA-256 and optional page suggestions. It does not prove the file belongs to the requested part. Existing different files are never overwritten. No recursive catalogue search or replacement-part selection is performed.
  3. Use the outline if available. contents_page identifies a page containing a textual table of contents; suggested_page is a keyword heuristic. pdfPage is 1-based; numbers printed inside contents lines are document labels and may have an offset. Check them against actual pages. No outline is normal for a short datasheet. A failed or unavailable helper means use the environment's PDF reader, not that the PDF is unusable.
  4. Read the relevant PDF pages with the environment's native PDF, browser or rendering tools. Inspect diagrams, pin tables, multi-column tables and curves visually when extracted text loses their associations. Search more widely if a required fact is missing; suggested pages are not exhaustive. The scripts do not render images or run OCR. A scanned PDF may still be readable visually.
  5. Confirm the manufacturer, family member and package before using pin numbers. Distinguish absolute maximum ratings, recommended operation and typical performance; retain test conditions. A full ordering suffix may be documented separately. Do not infer a package from a family cover alone. Unknown is not zero or false, and a typical application is not a universal requirement.
  6. During schematic creation/review, automatically preserve the useful facts actually read in MPN.notes.md beside the PDF, following reading and notes. Record pinout, electrical limits, thermal data and caveats only as relevant to the task, with PDF pages and source hash. A one-off answer need not produce a full component extraction. Reuse matching notes, inspect their scope, and recheck claims when the PDF or package changes. Notes are written by the agent, not inferred by the downloader.
  7. Compare facts with actual schematic connections or layout only when those are available. Report the conclusion, PDF/page evidence and unresolved questions. Successful download or text extraction is not electrical validation. Do not describe unread sections as checked.

Commands

sh
node scripts/download.mjs "https://example.com/datasheet.pdf" --out ./datasheets/part.pdf
node scripts/pdf-outline.mjs ./datasheets/part.pdf
node scripts/pdf-outline.mjs ./datasheets/part.pdf --find "absolute maximum"

Both commands output JSON. download exits 0 for a saved PDF even when its nested outline.status is unavailable, no_text or failed; exits 1 for a download/usage error. pdf-outline exits 2 when text navigation is unavailable/failed/empty, 1 for an input error. Output is bounded; inspect truncated before assuming all matches were returned. The helper scans text within 15 seconds/8 MiB; it does not install tools or maintain a cache. Read a local PDF directly on repeat tasks to avoid another download.

For a non-PATH Poppler installation, pass --pdftotext /absolute/path/to/pdftotext (or .exe), or set DATASHEETS_PDFTOTEXT. If absent, use your existing PDF tools; installation is optional. Downloads use a 30-second network timeout (configurable with --timeout, up to 120), at most 8 requests, and a 50 MiB response limit. The default output is ./datasheets/<URL-hash>.pdf; prefer a readable explicit filename. HTML containing several PDF candidates requires the agent to choose the correct link. Authentication challenges and script-only viewers may require the environment browser; no JavaScript from downloaded pages is executed.
