Flipt Feature Flag Management

Use this skill to manage Flipt feature flags for controlled feature rollouts.

Running Commands

Use the included script:

node .claude/skills/flipt/flipt.mjs <command> [options]

Commands

Command	Description
list	List all flags
get <key>	Get details for a specific flag
create / enable / disable / delete	Refuse with exit 2 and print the GitOps steps — see below
add-variant / remove-variant / set-rollout	Same

Reads work over the API; writes are deliberately refused. This Flipt is v2, GitOps-backed by a private state repo, so a merged change becomes visible within about a poll interval.

Never write through the API. Flag state is reviewed material — change flags by opening a PR against the state repo, never by calling the API. This skill refuses writes for that reason.

Treat FLIPT_API_TOKEN as a live secret: read it from env, never inline it, and don't copy it into anything new.

Flags live at /api/v2/environments/{env}/namespaces/{ns}/resources/flipt.core.Flag. The environment (civitai-app) and namespace (default) are discovered at runtime — the environment marked default: true, then its default namespace — so a second environment can't silently redirect reads. Override with FLIPT_ENVIRONMENT / FLIPT_NAMESPACE if ever needed.

Responses carry a revision equal to the flipt-state commit SHA, which is the quickest way to confirm a flag change has actually synced:

node .claude/skills/flipt/flipt.mjs list --json | head -3   # revision == your commit

Options

Flag	Description
--description <text>, -d	Description for new flag
--enabled	Create flag as enabled (default: disabled)
--variant	Create as variant flag (default: boolean)
--variants <keys>	Comma-separated variant keys (first is default)
--default <key>	Set default variant key
--rollout <pct>	Rollout percentage (default: 100)
--segment <key>	Segment key for rules (default: all-users)
--json	Output results as JSON
--quiet, -q	Minimal output
--force, -f	Skip confirmation prompts

Examples

# List all flags
node .claude/skills/flipt/flipt.mjs list

# Get a specific flag
node .claude/skills/flipt/flipt.mjs get gift-card-vendor-waifu-way

# Creating / toggling a flag goes through GitOps — see below.
# These commands exit 2 and print the steps:
node .claude/skills/flipt/flipt.mjs disable my-feature

# JSON output for scripting
node .claude/skills/flipt/flipt.mjs list --json

GitOps Integration

Flipt uses GitOps - flags are stored in the civitai/flipt-state repository. Changes made via the API are temporary and will be overwritten on the next Git sync (every 30 seconds).

For permanent changes, edit the repository directly:

# Clone the state repo
gh repo clone civitai/flipt-state /tmp/flipt-state

# Edit civitai-app/default/features.yaml
# Add your flag under the `flags:` section

# Commit and push
cd /tmp/flipt-state
git add -A && git commit -m "Add new feature flag" && git push

Flag Format in YAML

flags:
  - key: my-feature-flag
    name: my-feature-flag
    type: BOOLEAN_FLAG_TYPE
    description: Description of what this flag controls
    enabled: false
    # Optional: rollout rules
    rollouts:
      - threshold:
          percentage: 50
          value: true
      - segment:
          keys:
            - moderators
          operator: OR_SEGMENT_OPERATOR
          value: true

Safety Notes

1. Do not write through the API: it pushes an unreviewed commit to flipt-state main
2. Test before enabling: Use segments for gradual rollout
3. Coordinate with team: Others may be editing the same flags

Environment Setup

Copy .env.example to .env and configure:

cp .claude/skills/flipt/.env.example .claude/skills/flipt/.env

The skill needs FLIPT_URL and FLIPT_API_TOKEN to connect to Flipt.
