feature

feature is a skill for Claude Code from arbazkhan971/godmode. It costs 55 tokens per session (1,728 once invoked), scanned A, original, MIT.

Guidance for designing feature flags, which are switches that control whether code is enabled. It covers gradual rollouts, A/B tests, and kill switches using systems such as LaunchDarkly, Unleash, or Flagsmith.

In plain words
What is it for?
Use it to choose a flag strategy, inspect existing flags, plan staged releases or experiments, and identify flags that may no longer be needed.
Why use it?
It helps separate releasing code from turning it on, reducing the risk of deploying a change to everyone at once.

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 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.

Feature — Feature Flags & Progressive Delivery

Activate When

  • User invokes /godmode:feature
  • User says "feature flag", "gradual rollout"
  • User says "kill switch", "A/B test"
  • Deploying needs safer rollout or deploy/release decoupling

Workflow

Step 1: Flag Strategy Assessment

# Detect existing flag infrastructure
grep -r "launchdarkly\|unleash\|flagsmith\|split\|statsig" \
  package.json pyproject.toml 2>/dev/null

# Find existing flag usage
grep -rn "featureFlag\|isEnabled\|isFeatureEnabled" \
  src/ --include="*.ts" --include="*.py" 2>/dev/null | wc -l

# Check for stale flags (not evaluated in 30+ days)
grep -rn "featureFlag\|isEnabled" src/ \
  --include="*.ts" 2>/dev/null | head -20
FLAG STRATEGY:
  Current: None | Homegrown | LaunchDarkly | Unleash
  Flag needs: Release | Experiment | Ops | Permission
  Environments: Dev | Staging | Prod | Mobile

IF < 5 flags: Homegrown or Flagsmith OSS
IF 5-50 flags: Unleash or Flagsmith
IF 50+ flags with experiments: LaunchDarkly
IF strict data residency: self-hosted

Step 2: Flag Types

| Type       | Lifecycle   | Default | Duration  |
|------------|-------------|---------|-----------|
| Release    | Short-lived | OFF     | < 2 weeks |
| Experiment | Short-lived | CONTROL | < 4 weeks |
| Ops/Kill   | Permanent   | ON      | Forever   |
| Permission | Permanent   | OFF     | Forever   |

RELEASE RAMP:
  CREATE → INTERNAL → CANARY 1% → 5% → 25%
    → 50% → 100% → CLEANUP (within 2 weeks)

EXPERIMENT RAMP:
  CREATE → CONFIGURE → RUN → SIGNIFICANCE
    → PICK WINNER → CLEANUP (within 1 week)

Step 3: Targeting & Gradual Rollout

RULE PRIORITY (top to bottom):
  1. Individual overrides
  2. Employee targeting
  3. Beta segment
  4. Percentage rollout
  5. Default OFF

ROLLOUT STAGES:
  Internal (0.1%) 1d → Canary (1%) 1-2d
    → Early (5%) 2-3d → Expanding (25%) 3-5d
    → Majority (50%) 3-5d → Full (100%)

GATE CRITERIA (advance only if all pass):
  Error rate < baseline + 0.1%
  P95 latency < baseline + 10%
  Conversion > baseline - 2%
  Support tickets < baseline + 5%

STICKY BUCKETING:
  hash(flagKey:userId) % 10000 / 100
  Same user always sees same variant
  Increasing % adds users, never flips existing

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.

feature is a skill published in the GitHub repository arbazkhan971/godmode (26 stars, last pushed 8d ago), licensed MIT. It adds 55 tokens to every session and 1,728 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
