Feature Flag Strategy
Overview
Use this skill to manage feature flags as controlled release instruments, not permanent complexity.
Scope Boundaries
- Use this skill when the task matches the trigger condition described in
description. - Do not use this skill when the primary task falls outside this skill's domain.
Shared References
- Lifecycle decision rules:
references/flag-lifecycle-decision-rules.md
- Targeting and blast-radius guidance:
references/flag-targeting-risk-guidance.md
Templates And Assets
- Flag catalog template:
assets/feature-flag-catalog-template.csv
- Rollout plan template:
assets/flag-rollout-plan-template.md
- Retirement checklist:
assets/flag-retirement-checklist.md
Inputs To Gather
- Rollout objective, user segments, and release risk tolerance.
- Blast-radius constraints and required kill-switch latency.
- Operational/compliance constraints and on-call readiness.
- Flag platform capabilities, dependency behavior, and telemetry coverage.
Deliverables
- Flag definition with owner, type, kill-switch, and expiry.
- Rollout plan with progression gates and rollback policy.
- Lifecycle decision record including retirement criteria.
- Verification evidence for targeting and disable behavior.
Workflow
- Decide whether a flag is warranted using
references/flag-lifecycle-decision-rules.md. - Register flags in
assets/feature-flag-catalog-template.csvwith ownership and expiry. - Define rollout and rollback using
assets/flag-rollout-plan-template.md. - Validate targeting safety using
references/flag-targeting-risk-guidance.md. - Retire flags using
assets/flag-retirement-checklist.mdonce control is no longer needed.
Quality Standard
- Every flag has owner, kill-switch, and retirement date.
- Rollout and rollback criteria are measurable and pre-defined.
- Targeting rules are auditable and operationally safe.
- Retired flags are removed from code paths, not just disabled.
Failure Conditions
- Stop when flags lack ownership, expiry, or safe disable paths.
- Stop when targeting rules create unbounded or opaque blast radius.
- Escalate when accepted rollout risk exceeds policy thresholds.

graph-algorithms
Graph algorithm workflow for modeling entities/relations and selecting traversal, path, ordering, or flow strategies. Use when correctness or performance depends on graph representation and algorithm choice; do not use for schema-only modeling or deployment topology planning.
14bash-style-guide
Style, review, and refactoring standards for Bash shell scripting. Trigger when `.sh` files, files with `#!/usr/bin/env bash` or `#!/bin/bash`, or CI workflow blocks with `shell: bash` are created, modified, or reviewed and Bash-specific quality controls (quoting safety, error handling, portability, readability) must be enforced. Do not use for generic POSIX `sh`, PowerShell, or language-specific application style rules. In multi-language pull requests, run together with other applicable `*-style-guide` skills.
11architecture-clean-architecture
Clean Architecture workflow for enforcing dependency direction, stable domain boundaries, and use-case-centered application design. Use when teams must separate business rules from frameworks and delivery mechanisms; do not use for isolated module cleanup without boundary implications.
11powershell-style-guide
Style, review, and refactoring standards for PowerShell scripting. Trigger when `.ps1`, `.psm1`, `.psd1` files, or CI workflow blocks with `shell: pwsh` or `shell: powershell` are created, modified, or reviewed and PowerShell-specific quality controls (error handling, parameter validation, readability, operational safety) must be enforced. Do not use for Bash, generic POSIX `sh`, or language-specific application style rules. In multi-language pull requests, run together with other applicable `*-style-guide` skills.
10github-codeowners-management
Govern CODEOWNERS rules so review routing reflects real ownership and risk boundaries on GitHub. Use when repository ownership mapping or mandatory reviewer rules must be defined, updated, or audited; do not use for non-GitHub runtime architecture or data-layer design.
9security-authentication
Security workflow for authentication architecture, credential lifecycle, and session/token assurance. Use when login, identity proofing, MFA, or session security decisions are required; do not use for authorization policy design or non-security quality tuning.
