Agent Context Editor

Cross-agent context inspection and view-state controls for coding agents.

The project currently ships two adapters:

Adapter	Package / app	Stable scope
Pi extension	pi-context-editor@0.4.0-alpha.1	/ctx in Pi TUI and Pi Desktop; shared unit editor with visual-only state
DeepSeek Harness	context-editor-deepseek-harness@0.1.1	Context Editor tab with independent reasoning/answer units
Pi Context Desktop	jermaine123123/pi-app context-editor-v0.1.4	Windows x64 community desktop build

中文说明：README.zh-CN.md

What it does

The DeepSeek Harness adapter reads the durable Session event log and projects user, AI and tool records into a separate Context Editor view. Reasoning and answer blocks in one AI turn are independent editable units: you can search, select, hide, restore and persist either unit without hiding the other. Hide, restore, reset and undo events are stored in a context_editor sidecar.

The original Harness Session log and model input are not rewritten. Hiding is a view operation in this release and does not reduce model token usage. The Pi TUI uses the same Record/Unit Core as the other adapters. Pi TUI view events and preferences are stored in an atomic <sessionFile>.context-editor.json sidecar; Desktop/RPC may keep writing host-native CustomEntry events. Neither path replaces Tool Output or registers a context hook, so the model receives the same messages before and after a visual edit.

This is an independent community project. It is not affiliated with, endorsed by or sponsored by DeepSeek, Pi, or their maintainers.

Install

Pi extension

Download pi-context-editor-0.4.0-alpha.1.tgz from the release assets, then install it with the Pi package manager:

pi install ./pi-context-editor-0.4.0-alpha.1.tgz

For Pi Desktop registration, run adapters/pi-extension/scripts/install-desktop.ps1 with PowerShell. The script auto-discovers Pi and accepts -PiPath and -DesktopExePath when an installation is non-standard. Fully restart Pi Desktop before entering /ctx.

DeepSeek Harness

Download context-editor-deepseek-harness-0.1.1.tgz and install it into a Harness profile using the official CLI:

dsh plugin --profile <profile> add ./context-editor-deepseek-harness-0.1.1.tgz

The adapter targets Harness Developer Preview commit 47f943859bef60e4160492346772ded9b24f765a0 and CLI @deepseek-ai/dsh@0.1.0-rc.6. See COMPATIBILITY.md for the tested host boundary.

Language behavior

The Context Editor follows the host language automatically. Chinese locales (zh-*) use the Chinese UI; all other system/browser locales use English. Pi Context Desktop follows its existing app language setting when one is available, and otherwise uses the system locale. Pi TUI, Pi's native /ctx dialogs and the DeepSeek Harness view resolve the locale when they open. This only translates editor controls and status messages; session content is never translated.

pi-app/ is intentionally excluded from this repository. It remains a separate Git repository and fork so its upstream history, Electron sources and large build outputs do not become a dependency of the adapters.

Development

Requirements: Node.js 22.19+ (Node 24 is used by the recorded acceptance run) and npm.

npm ci
npm run verify

npm run verify regenerates the Pi adapter's vendored Core and bundled dist/index.js, type-checks the Pi adapter and Core, runs all unit and adapter fixtures, rebuilds the DeepSeek Core/client artifacts, and checks both npm tarballs for unexpected files. Generated Core copies and bundles must not be edited directly.

Known limits and roadmap

The alpha release deliberately does not rewrite the active conversation, remove items from model context, compress tokens, replace Tool Output, or add more hosts. Hiding is strictly a Context Editor view operation; it is not a model context control. Next steps are a real context-exclusion contract, additional host adapters, signed desktop distributions and a broader fixture suite.

Please report reproducible host compatibility issues with the relevant host version, adapter version and sanitized logs. Do not attach session logs that contain prompts, secrets or personal data.
