cli AGENTS.md

Coding instructions for a TypeScript command-line application that manages DevCycle feature flags, which control how software features are enabled. The project also includes an API client, authentication and a Model Context Protocol server.

In plain words
What is it for?
It helps develop CLI commands, API and authentication code, interactive output, utilities and the MCP server.
Why use it?
It keeps changes consistent with the project's directory structure, Yarn tooling, formatting and commit conventions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cli AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DevCycle CLI Coding Standards and Conventions

Project Structure

TypeScript CLI application built with oclif framework for DevCycle feature flag management.

Main Entry Points

  • CLI Binary: bin/run - Main CLI entry point
  • MCP Server: dist/mcp/index.js - Model Context Protocol server
  • Source Root: src/index.ts - TypeScript entry point

Core Directories

  • src/commands/ - All CLI commands organized by feature
  • src/api/ - API client code and schemas
  • src/auth/ - Auth handling (API keys, SSO, tokens)
  • src/ui/ - Interactive prompts and output formatting
  • src/utils/ - Shared utilities and helpers
  • src/mcp/ - Model Context Protocol implementation

Configuration and Tooling

  • Uses Yarn with workspaces
  • Always use yarn not npm

Formatting

  • Defer all formatting to Prettier for supported file types (JavaScript, TypeScript, JSON, Markdown, etc.)

Git Commit Message Conventions

  • Follow Conventional Commits specification: <type>: <description> (scopes rarely used)
  • Valid types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert
  • Description should be imperative mood, lowercase, single sentence
  • Examples: feat: add support for multi-threaded tests, fix: correct response for invalid input

Aviator CLI Workflow (optional)

  • Use Aviator CLI (av) for managing stacked branches: av branch chore-fix-invalid-input
  • Sync and push changes: av sync --push=yes
  • Create PR: av pr --title "<title>" --body "<body>"
    • Title follows Conventional Commits, body uses markdown/bullets
    • av pr will push the branch
  • GitHub PR descriptions should be short and focus on why changes were made, not what changed, limit describing files and tests changed.

Naming Conventions

  • Use camelCase for files, folders, and variables (starting with lowercase)
  • PascalCase for classes and interfaces
  • SCREAMING_SNAKE_CASE for constants
  • kebab-case for CLI flags and file names

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
