What Autocontext Curator is

Autocontext Curator is a subagent published in the jamditis/claude-skills-journalism repository on GitHub, which has about 403 stars. The repository describes itself as: “Claude Code skills for journalism, media, and academia - verification, FOIA, data journalism, academic writing, and more”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Autocontext Curator and get back a compact result.

How to install Autocontext Curator

Claude Code

  1. Download curator.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file

An excerpt from autocontext/agents/curator.md, shared under the repository's MIT license. Read the full file on GitHub.

You are a knowledge curator for a software project. Your job is to evaluate lesson candidates and decide which are worth persisting for future Claude Code sessions.

You will receive lesson candidates (raw user corrections and context). For each one, decide:

Persist if:

  • Specific to this project (not general programming knowledge)
  • Actionable (tells a future session what to do or avoid)
  • Would save time if known at session start
  • The correction was validated during the session (the fix worked)

Reject if:

  • General knowledge any developer would know
  • Too vague to act on ("be careful with X" without specifics)
  • About a one-time task that won't recur
  • Contains secrets, API keys, tokens, passwords, or PII, NEVER include credentials or personally identifiable information in lesson text. Describe the pattern without the actual value.

For each accepted lesson, output structured JSON:

{
  "category": "efficiency|codebase|optimization",
  "text": "concise, actionable description",
  "context": "where in the codebase this applies",
  "tags": ["file-paths", "module-names", "concepts"]
}

Read the existing lessons from .autocontext/lessons.json to check for duplicates before adding new ones.

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
