pi-dtime

English | 简体中文

pi-dtime is a lightweight Pi extension that appends the duration and local completion time after every fully settled agent response.

Features

• Measures from the first agent_start until agent_settled, so automatic retries, compaction recovery, and queued continuation remain part of one complete run.
• Uses a monotonic clock for elapsed time, so wall-clock adjustments do not corrupt the duration.
• Records the local wall-clock completion time and includes the full date when a run crosses a local date boundary.
• Optionally follows the active pi-di18n /lang locale for copy, duration units, and date/time formatting.
• Re-renders historical response-timing entries in the current locale without changing the persisted v1 data contract.
• Persists a TUI-only custom transcript entry without using the footer, status bar, or a live timer.
• Never calls sendMessage; timing entries are not added to later LLM context.
• Has zero runtime dependencies beyond Pi's bundled peer packages.

Installation

Install the latest npm release:

pi install npm:pi-dtime

To make timing lines follow /lang, install both packages:

pi install npm:pi-di18n
pi install npm:pi-dtime

Install the pinned GitHub release:

pi install git:github.com/ssdiwu/[email protected]

Restart Pi after installation, or run /reload in an existing session.

Localization behavior

When pi-di18n is available, pi-dtime connects through the public pi-core/i18n/requestApi contract and reads the current locale at render time. Changing /lang and reloading therefore updates both new and existing timing entries.

The maintained locale set matches the 25 TUI locales currently shipped by pi-di18n: cs, da, de, el, en, es, fi, fr, hi, id, it, ja, ko, nl, pl, pt-BR, pt-PT, ro, sg, sv, tr, uk, vi, zh-CN, and zh-TW.

If pi-di18n is absent or its API is unavailable, pi-dtime remains fully functional and uses Simplified Chinese. Unknown valid locales follow the i18n fallback and default to English.

Development

git clone https://github.com/ssdiwu/pi-dtime.git
cd pi-dtime
npm install
npm run typecheck
npm test
npm pack --dry-run

To try the local checkout without installed extensions:

pi --no-extensions -e ./index.ts

The current tested compatibility baseline is @earendil-works/pi-coding-agent 0.84.1. Localization integration targets the pi.i18n.v1 contract exposed by pi-di18n.

Project layout

• index.ts — Pi extension entry point, timing lifecycle, and optional i18n bridge.
• src/locales.ts — locale messages, bundle metadata, aliases, and fallback rules.
• tests/ — extension registration, localization, and behavior regression tests.
• doc/README.md — documentation map and source-of-truth boundaries.
• AGENTS.md — implementation and verification constraints.

Scope

pi-dtime measures only complete runs of the main Pi agent. It does not measure individual tool calls or independent pi-dteam workers.
