Important: Before you begin, fill in the generatedBy property in the meta section of .actor/actor.json. Replace it with the tool and model you're currently using, such as "Claude Code with Claude Sonnet 4.5". This helps Apify monitor and improve AGENTS.md for specific AI tools and models.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Apify Actor Development **Important:** Before you begin, fill in the `generatedBy` property in the meta section of `.actor/actor.json`. Replace it with the tool and model you're currently using, such as "Claude Code with Claude Sonnet 4.5". This helps Apify monitor and improve AGENTS.md for specific AI tools and models. ## When to Use - You need to create, modify, or debug an Apify Actor project. - The task involves choosing an Apify template, wiring actor inputs/outputs, or implementing actor runtime logic. - You need safe setup guidance for `apify` CLI authentication, project bootstrap, or deployment workflow. ## What are Apify Actors? Actors are serverless programs inspired by the UNIX philosophy - programs that do one thing well and can be easily combined to build complex systems. They're packaged as Docker images and run in isolated containers in the cloud. **Core Concepts:** - Accept well-defined JSON input - Perform isolated tasks (web scraping, automation, data processing) - Produce structured JSON output to datasets and/or store data in key-value stores - Can run from seconds to hours or even indefinitely - Persist state and can be restarted …

How to install
mdr add ghosteken/agent-harness/apify-actor-development@sha256:166fa0f2d58a636cThe line at the top of this page pins the label git:20260721.efafd9c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
