Readme

@dreki-gg/pi-past-chats

Reference previous Pi sessions inline with @chat: or @session:.

Usage

Type either prefix in the Pi editor:

Use the approach from @chat:
Compare this with @session:

Autocomplete shows sessions from:

the current working directory, and
external folders configured in .pi/past-chats.json.

Selecting a suggestion inserts a stable token such as @chat:9ab12cd34ef0. When you submit the prompt, the extension injects a hidden context message with:

session title/name
session file path
cwd/source folder
created/modified dates
message count
deterministic handoff summary
optional cached AI handoff summary when enabled

The agent can use the injected summary immediately, or read the listed session JSONL file for deeper details.

Agent tool: `search_past_chats`

The extension also exposes a tool the agent can call directly to discover relevant prior sessions:

Input: query (fuzzy search string) and optional limit (default 10).
Scope: the current working directory plus folders configured in .pi/past-chats.json (same index as autocomplete).
Output: for each match, the session JSONL file path, a snippet showing why it matched, and a fuzzy score (lower is better), sorted best match first.

The agent then reads any returned path with the built-in read tool to inspect the full conversation. This lets the agent narrow down which past chats discussed a topic before pulling in the detail it needs.

Commands

/past-chats list
/past-chats add <path> [label]
/past-chats remove <label|path>
/past-chats refresh
/past-chats summarize @session:<id>

Examples:

/past-chats add ../api API
/past-chats add /Users/me/work/mobile Mobile App
/past-chats list

Config

Project config lives at:

.pi/past-chats.json

Example:

{
  "folders": [
    { "path": "../api", "label": "API" },
    { "path": "/Users/me/work/mobile", "label": "Mobile App" }
  ],
  "summary": {
    "ai": false,
    "provider": "openai",
    "model": "gpt-5-mini"
  }
}

Notes:

The current cwd is always included implicitly.
Folder paths are resolved relative to the current cwd unless absolute.
AI summaries are opt-in with summary.ai: true and require a configured provider/model/API key.
If AI summary generation fails, the extension falls back to deterministic summaries.

Cache

AI summaries are cached in:

.pi/past-chats-cache.json

Cache entries are invalidated by session path, modified timestamp, summary version, provider, and model.

Install

pi install npm:@dreki-gg/pi-past-chats
