Resources and reference implementations for extending Seer with custom file-preview plugins.
Replace the requirement placeholder below, then give the complete instruction to your coding agent:
Read and follow the Seer plugin development guide at https://raw.githubusercontent.com/ccseer/Seer-Plugins/refs/heads/master/plugin_development_guide.md. Treat it as the source of truth for architecture, plugin.json, implementation, validation, and packaging. If the guide is unavailable, stop and report that before proceeding.
Before doing any work, inspect the Requirement below. If it is missing, unchanged placeholder text, or too ambiguous to implement, ask one clarifying question and wait. Do not infer the missing requirement.
Once clear, choose Convert or DLL and briefly justify the choice, then implement a complete, installable plugin in the current workspace. Do not modify Seer itself or stop at a plan or code snippets.
Follow every applicable validation step in the guide and report the actual results. Run an in-app Seer preview test when possible; otherwise explicitly state that runtime verification was not performed.
Requirement: [REPLACE THIS PLACEHOLDER with the plugin request.]
