drin-feature-flag-workflow

drin-feature-flag-workflow is a skill for Claude Code from pedrol-cmd/brain-drin. It costs 23 tokens per session (211 once invoked), scanned A, original, MIT.

A system for using feature flags, which are on/off controls around parts of an application. They support gradual releases, experiments, emergency switches, and access for selected users.

In plain words
What is it for?
Use it to plan flag lifecycles, roll features out gradually, run A/B tests, create kill-switches, and remove old flags from the code.
Why use it?
Feature flags separate deploying code from releasing it to everyone. This makes it easier to test changes with limited users and disable problematic features.

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

drin-feature-flag-workflow 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 6d 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 it actually says

Feature Flag Workflow

Purpose

To decouple deployment from release, allowing for safer launches and real-world testing.

Patterns

  • Release Toggles: Gradual rollout to % of users.
  • Experiment Toggles: A/B testing variations.
  • Ops Toggles: Kill-switches for heavy or buggy features.
  • Permission Toggles: Enabling features for specific tiers or beta users.

Lifecycle

  1. Create: Define flag in code and manager (LaunchDarkly/GrowthBook).
  2. Implement: Wrapped code blocks with flag checks.
  3. Rollout: Increase % monitoring telemetry.
  4. Cleanup: Relentlessly remove flags once feature is permanent.

Rules

  • Name flags by intent, not implementation.
  • Don't leave flags in the code for > 3 months (Tech Debt).
Changes

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.
