macro: Skill for Claude Code

.agents/skills/feature-flags/SKILL.md

feature-flags is a skill for Claude Code, Codex from macro-inc/macro. It costs 81 tokens per session (1,407 once invoked), scanned A, original, AGPL-3.0.

A feature-flag helper for defining, reading, and removing switches that control whether parts of an application are enabled. A feature flag is a setting that lets code be turned on or off without removing it.

In plain words
What is it for?
Use it to gate web-app features or Rust backend behavior with code checks or environment settings.
Why use it?
It helps roll out changes gradually, disable a feature quickly, or test behavior for selected users or environments.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is macro-inc/macro's own configuration. It tells Claude Code and Codex how to work on macro itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything macro configures →

About the project

Macro is a shared workspace that brings email, chat, documents, tasks, AI agents, calls, and customer relationship management into one connected system. It is for teams that want work information and cross-references in a single searchable environment. The catalogue entries provide skills, instructions, MCP integrations, commands, settings, and an agent for working with Macro.

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

feature-flags 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 10d 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.

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.
