deepseek-ai/deepseek-harness/website/AGENTS.md

Follow the root instructions, the documentation standard, and the documentation workflow. website/ owns only VitePress configuration, presentation assets, and the publication manifest. This file is the only maintained Markdown file in this subtree. Keep canonical prose and generated catalogs in their owning docs/ tier, then expose selected pages through docs.ts. Never add locale, route, API, or copied documentation trees such as website/zh-CN/, website/en/, or website/api/. The projector writes disposable Markdown to the ignored website/.generated/ directory. Never edit or commit .generated/,…

Custom personas with specific tools, instructions, and behaviors. Use for orchestrated workflows with role-based tool restrictions. Use reasoning-effort to set the reasoning level for the custom agent's model: The selected model must support the configured level. If omitted, the runtime resolves the effort from the model configuration and, when applicable, the parent agent. Sources: built-in aliases, specific tools, MCP servers (<server>/*), extension tools. Special: [] = no tools, omit = defaults. Body reference: #tool:<name> To discover available tools, check your…

vscode / copilotcli

microsoft/vscode/extensions/copilot/src/extension/chatSessions/copilotcli/AGENTS.md

This folder contains the Copilot CLI integration for VS Code Chat. It enables users to open a new Chat window and interact with a Copilot CLI agent instance directly within VS Code. VS Code provides the UI, Copilot CLI SDK provides the smarts. Important: The Copilot CLI agent functionality is powered by the @github/copilot/sdk package. See the SDK package for full type definitions. The integration follows VS Code's platform layering pattern with three layers:

vscode / common

microsoft/vscode/extensions/copilot/src/platform/authentication/common/AGENTS.md

IAuthenticationService manages GitHub and Copilot authentication. It provides GitHub sessions (OAuth tokens) and Copilot tokens (CAPI tokens). getGitHubSession requires a kind parameter. Choose thoughtfully: Returns AuthenticationSession (never undefined). Throws if the user cancels. Requires createIfNone with a StrictAuthenticationPresentationOptions containing a localized detail string explaining why auth is needed: Same as above but forces re-authentication even if a session exists. Use when the current token has lost authorization: Returns AuthenticationSession | undefined. Never shows UI. Use when auth is optional: For…

vscode / agentHost

microsoft/vscode/src/vs/platform/agentHost/AGENTS.md

Node runtime service construction is documented separately in node/serviceBootstrapping.md. Host startup timings, process-lifetime correlation, and session workload counts are documented in PERFORMANCE.md. Status: COMPLETE (2026-07-01) All waves A–D and gates G-B1, G-C1, G-C2, G-D1 are done. Codex, Claude, and Copilot all use the unified orchestrator path. Codex advertises multipleChats: { fork: true, sideChat: true }. Model-backed peer, fork, and side-chat parity scenarios run in deterministic replay. The operational chat surface (send/abort/model/agent/history) is fully chat-addressed and uniform across harnesses. Session ownership…

vscode / state

microsoft/vscode/src/vs/platform/agentHost/common/state/AGENTS.md

This directory contains the VS Code-facing wrappers around the Agent Host Protocol (AHP) state model. Read this before modifying protocol types. The generated protocol includes the Changesets model: The generated copy intentionally carries the optional CreateChatParams.title on top of the .ahp-version source commit 6eec1b91. Until the recorded pin advances to an AHP commit containing this field, preserve or reapply this generated delta when syncing. Neither titles nor initial messages require an additional capability; source-based creation still uses the existing fork…

vscode / prompts

microsoft/vscode/src/vs/platform/agentHost/node/copilot/prompts/AGENTS.md

This directory customizes the system prompt for Copilot CLI agent host (ahp+cli) sessions. Read this before changing how the system message is built or adding per-model / per-tool guidance. It mirrors the Copilot extension's extensions/copilot/.../prompts/node/agent/ (agentPrompts), but the agent host runs in its own process and cannot use prompt-tsx, so contributors return plain data the SDK accepts directly. Unless the matching chat.agentHost.copilot.modelCapabilityOverrides entry provides a YAML promptOverrideString or promptOverrideFile containing systemPrompt, resolveSystemMessageConfig(model, context) layers, in order: The per-model prompt override…

vscode / imageCarousel

microsoft/vscode/src/vs/workbench/contrib/imageCarousel/AGENTS.md

A generic workbench editor for viewing collections of images in a carousel/slideshow UI. Opens as a modal editor pane with navigation arrows, a caption, and a thumbnail strip. The image carousel is a self-contained workbench contribution that follows the custom editor pattern: Clicking an image attachment pill in chat (when chat.imageCarousel.enabled is true) executes the workbench.action.chat.openImageInCarousel command, which collects request attachment images together with response-derived images for the current chat session and opens them in the carousel. MIME types are…

transformers

huggingface/transformers/.ai/AGENTS.md

Run make style (or make fix-repo) as the last step before opening a PR. Hosted review agents read this file via the root AGENTS.md / CLAUDE.md symlinks. Local agents wire their own assets: make codex (→ .agents/), make claude (→ .claude/). If your approach is materially different, say why a second PR is needed in the issue. - No one-off PRs for tiny edits (a single typo, an isolated lint fix). Mechanical cleanups are fine, but not as a first…

spec-kit

github/spec-kit/AGENTS.md

GitHub Spec Kit is a comprehensive toolkit for implementing Spec-Driven Development (SDD) - a methodology that emphasizes creating clear specifications before implementation. The toolkit includes templates, scripts, and workflows that guide development teams through a structured approach to building software. Specify CLI is the command-line interface that bootstraps projects with the Spec Kit framework. It sets up the necessary directory structures, templates, and AI agent integrations to support the Spec-Driven Development workflow. The toolkit supports multiple AI coding assistants, allowing…
