A pi extension that adds a /context command for pinning files and glob patterns to chat sessions. Pinned file contents are injected into the LLM conversation automatically.

cp pin-context.ts ~/.pi/agent/extensions/pin-context.ts

mkdir -p .pi/extensions
cp pin-context.ts .pi/extensions/pin-context.ts

pi -e ./pin-context.ts

Extensions in auto-discovered locations (~/.pi/agent/extensions/ or .pi/extensions/) can be hot-reloaded with /reload.

/context add <glob>              - Pin files matching glob
/context add <glob> --paths      - Pin file paths only (no content)
/context add <glob> --persist    - Persist across sessions
/context remove <pattern>        - Remove a pinned pattern
/context clear                   - Clear all pinned context
/context show                    - Show pinned context (TUI overlay)

# Pin all markdown files (including those in dot-directories like .agents/)
/context add **/*.md

# Pin source files, paths only
/context add src/**/*.ts --paths

# Pin config and persist across sessions
/context add tsconfig.json --persist

• Glob patterns match files inside dot-directories (.agents/, .git/, etc.)
• Files over 500KB are skipped automatically
• Persistent pins survive session restarts (stored in .pi/pin-context.json)
• TUI overlay for browsing and managing pinned context (/context show)
• Tab completion for subcommands, patterns, and flags
