LaunchDarkly Agent Skills

Flag and prompt changes made by asking, not clicking: release a feature to a slice of the customer base, or swap the model behind a product's AI, without opening the LaunchDarkly dashboard.

Labsco Summary

ShowHideCreates, rolls out and retires LaunchDarkly feature flags and AI configs on request, and shows you a plan before it adds LaunchDarkly to a codebase.

Flag work, by asking for it.

Feature flags are switches you flip in a browser to change what a running product does, without shipping new code. This package hands that work to a coding assistant:

add a new switch, named and written the way your codebase already does it
let a change reach a tenth of your users, then widen it or switch it off
take a finished switch out of the code and open the pull request

Every one of those lands on a real LaunchDarkly account, so there is nothing to try here without one.

Four kinds of work.

The 16 skills divide by what they act on:

2 on getting it into a project
4 on the life of a flag
3 on judging a release
7 on prompts and models as config

That last group is the biggest, and it is about AI features rather than ordinary switches.

Adding LaunchDarkly starts with a plan.

Installing into an existing codebase is deliberately slow. One step reads the project to work out what language it uses, a second writes down everything that will be touched, and only the third edits a file — the plan is put in front of you first, and keys go wherever you say rather than into the source.

Skills

What has to happen before any of the rest is usable: sizing up a repository that already exists, settling the plan before a file is touched, installing the right toolkit and starting it up, building one switch you can watch flip, and authorising the assistant so it can act on the account directly. For teams on GitHub, one more maps a repository so new pull requests get their flags added automatically.

launchdarkly-factory-settingsControls Factory, LaunchDarkly's GitHub automation that can wrap new code changes in on/off switches and release them by itself, or explains, without changing anything, why it skipped a particular pull request.onboardingThe very first setup: it puts LaunchDarkly into a project, builds one working switch you can watch flip on and off, and commits nothing until you have said yes.

It does not just look at your flags — it changes them.

CONNECTS TOYour LaunchDarkly account

Authorising this is a browser sign-in rather than a key: the hosted server uses OAuth, so there is no API token to generate, paste or rotate.

The login you authorise with sets the ceiling. If its role is not allowed to create and delete flags, the connection breaks just after the consent screen instead of during it.

What authorising it lets it see.

every flag in the projects that login can reach, and what each is serving right now

the prompts and model choices a shipped AI feature runs on

logs, traces and grouped errors coming off a live product

the dashboards built on top of those

And what it can alter.

make a flag, and destroy one

switch a flag on or off, and rewrite who it applies to

add a prompt configuration, edit it, or delete it outright

Whatever that role is barred from, this is barred from too — down to individual projects and environments.

Two deployments do not have this server at all: accounts on LaunchDarkly's federal or European Union instances have to run the local one instead.

INSTALL

Two ways in, and they are not the same:
the plugin brings the connection, the CLI brings only the skills. The CLI line names launchdarkly/agent-skills, this same repository under its older name.

TERMINAL

Paste one line in a terminal

npx skills add launchdarkly/agent-skills

PLUGIN MARKETPLACE

Add the marketplace, then install the plugin

Typed inside the agent's own prompt, not in a terminal. The marketplace is called launchdarkly-ai-tooling, which is the part after the @.

01/plugin marketplace add launchdarkly/ai-tooling
02/plugin install launchdarkly@launchdarkly-ai-tooling
