What it does

Summarize Document is an agent skill from sgharlow/claude-code-recipes. Summarize a long document into an executive summary, key points, and role-specific implications. Use when the user says "summarize this document", "give me the key points", "do I need to read this?", or drops a long PDF, report, or contract and asks what matters in it.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/summarize.md`).

It sits in Writing & Content, covering Summarization. The repository describes itself as: 100 field-tested Claude Code recipes for knowledge workers — prompts, steps, and 6 installable graded skills.

When your agent uses it

  • The user says summarize this document
  • Give me the key points
  • Do I need to read this?
  • Drops a long PDF

Example prompts

  • “summarize this document”
  • “give me the key points”
  • “do I need to read this?”
  • “/summarize-document”

Workflow steps

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

  1. Confirm the target file and the reader's context — role, why they are reading it, and
  2. Read the full document. For very long documents, read in passes: structure first
  3. Produce, in order
  4. Verify: re-scan the document for any section not represented in the key points; either

What it can do on your machine

Read from SKILL.md and the folder at commit 9157c9a. 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

Summarize Document loads about 539 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 267 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~539

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 267 words (~539 tokens).

“Read a long document and return a decision-ready digest tuned to the reader's role. The summary must be faithful: every claim in it traces to the document, with section or page references where the format allows.”
