Feature Flag Release Prompt

Decouple deploy from release — a feature-flag rollout plan with the flag's default, targeting, kill switch, and the cleanup that stops flags becoming permanent debt.

Open in Markdown Output Builder

Overview

Feature flags let you ship code dark and release it on your terms — but ungoverned flags become permanent technical debt and a config-driven outage waiting to happen. This prompt plans a flag-based release: the safe default, the targeting and rollout sequence, the kill-switch behavior, and — the step most teams skip — the cleanup plan that retires the flag once it's fully rolled out.

How to use this resource

Describe the flagged release

Note what ships behind the flag, who should get it and when, and what the safe default is. The plan covers rollout and the cleanup most teams skip.
Open this resource in Markdown Output Builder

Load the prompt into Markdown Output Builder and fill in the release. It returns the flag plan - default, targeting, kill switch, cleanup - as a clean Markdown checklist.
Walk through the rollout and kill switch

Read the safe default, the targeting and rollout sequence, the kill-switch behavior, and the retirement step that stops the flag becoming permanent debt.
Fill the gaps before you flip it

Confirm the kill switch works and the cleanup is scheduled, then roll the flag out behind the plan.

Why This Works

A safe 'off' state makes the kill switch trustworthy
Planning cleanup up front stops flags accumulating into debt
Handling mid-session flips prevents the subtle data bugs flags cause

Best for

Teams with feature-flag infrastructure
Risky features that benefit from instant disable
Releases where deploy and release should be separate decisions

Not for

Percentage-based canary metrics — use the Staged & Canary Rollout Prompt
Building the flag system itself

Use cases

Planning a dark launch behind a feature flag
Defining a kill switch for a risky feature
Preventing feature flags from becoming permanent debt

FAQ

Will this feature flag prompt handle canary rollout percentages and metrics?

It plans percentage rollout under the TARGETING step — internal, percentage, segments, and the sequence — but it does not define canary success metrics or thresholds, and notFor routes that to the Staged & Canary Rollout Prompt. Markdown Output Builder returns the plan as a Markdown checklist; you and your team still decide the actual percentages and gates.

Which items does the CLEANUP step of a feature flag release plan cover?

The CLEANUP step names when the flag is removed, who owns it, and the dead-code removal once it's permanently on — enforcing the rule that every flag needs a documented removal plan, no permanent flags by default. Markdown Output Builder formats this as a section of the checklist; scheduling and doing the removal stays with your team.

What happens to in-progress user actions when a feature flag is flipped off?

The STATE SAFETY step is where you plan exactly that — what happens to in-flight work or data when the flag flips mid-session — alongside the KILL SWITCH step requiring that flipping off be safe instantly under load. The output is a written plan, not a tested guarantee; confirm the behavior in your own system before relying on it.

ROLE
You are planning a feature-flag-gated release that decouples deploying the code from turning it on.

INPUT
The feature and flag:
[What the flag controls and who it should reach]

PRODUCE A FLAG RELEASE PLAN
1. DEFAULT: the flag's safe default (off), and what the system does when it's off.
2. TARGETING: how the flag is rolled out — internal, percentage, segments — and the sequence.
3. KILL SWITCH: how flipping the flag off behaves, and that it's safe to do instantly under load.
4. STATE SAFETY: what happens to in-flight work or data when the flag flips mid-session.
5. CLEANUP: when the flag is removed, who owns it, and the dead-code removal once it's permanently on.

RULES
- Off must always be a safe, complete state.
- Every flag needs a documented removal plan — no permanent flags by default.

OUTPUT
A flag release plan covering default, targeting, kill switch, state safety, and the cleanup/removal step.
