Summary

Ports the onboardingV2 skill from launchdarkly/experimental-agent-skills into skills/onboarding, and adds the matching eval suite.

  • Onboarding now runs quietly: no roadmap table, no onboarding log file, no account question up front. State is detected from the repo so "continue onboarding" resumes.
  • MCP moves to the end: the flow reaches the first flag without it and only offers it after the flag works.
  • The first flag ends in a live reveal: a flag-gated banner in the running app that the user flips themselves.
  • MCP config guidance consolidates on the unified mcp/launchdarkly server and treats mcp/fm and mcp/aiconfigs as deprecated (migration is always asked, never automatic).
  • Files the V2 flow no longer uses are removed: first-flag/, references/1.8-summary.md, references/1.9-editor-rules.md.
  • New evals/onboarding suite covering kickoff voice, monorepo ambiguity, MCP deferral, and drift handling; registered in the eval manifest, package scripts, and README.

Testing

  • Manual (describe below)

python3 scripts/validate_skills.py, python3 scripts/generate_catalog.py --check, python3 -m unittest discover -s tests, and (cd evals && npm test) all pass.

npm run eval:onboarding scores 4/4 (100%), locally and in CI.

Notes

  • PR Onboarding UX: 3-phase roadmap, celebration card, file-write previews, env-aware URLs #62 (improve/onboarding-ux) also changes onboarding UX and predates the V2 rewrite. It likely conflicts with, or is superseded by, this port.
  • Bugbot flagged several flow gaps that exist verbatim in the upstream V2 skill and are not port artifacts (hardcoded default project after MCP setup, dashboard links interpolating unresolved keys, the wrap-up never routing back to the MCP offer, and the no-account placeholder path conflicting with "do not proceed until initialization is verified"). Left as-is here and answered in the review threads; worth a follow-up upstream.
Implementation details

Skill

  • skills/onboarding/SKILL.md is the V2 orchestrator, adapted to this repo: name/version stay onboarding, companion-skill installs point at launchdarkly/ai-tooling, and nested skills are referenced by their local paths. Additions on top of the source: the SDK key-type rule, the "non-LaunchDarkly dependency changes need approval" edge case, and a references list.
  • Every other ported file is byte-identical to the source except for renumbered parent step references and the removal of onboarding-log references in mcp-configure (the V2 flow writes no log).
  • Two contradictions inherited from the source were fixed: the edge case claiming mcp/fm needs no migration (it conflicted with the adjacent deprecation prompt), and Cursor auth telling users to toggle on "LaunchDarkly feature management" when the config written is named "LaunchDarkly".
  • Added skills/onboarding/README.md (the skill had none, and the eval manifest renders score badges into it); refreshed marketplace.json and the root README description; regenerated skills.json.

Evals

  • evals/onboarding/promptfooconfig.yaml adapts the source suite's three cases (kickoff, monorepo, drift) and adds a case asserting MCP is neither configured nor raised with the user before the flag works. Lean mode (allow_builtins: false) with per-test max_turns keeps runs to the graded beats.
  • Because lean mode gives the agent no file tools, each codebase_context states its listing as the result of the repository scan. Without that framing the agent sees no app and every fixture takes the skill's "no runnable app" branch, which is not the state under test.
  • The trajectory assertions match how the flow actually unfolds: the monorepo check scans every ask-question call rather than only the first, and the MCP check is scoped to the calls before create-flag, since the MCP offer at the end of the flow is the correct behavior. The drift rubric reads the assistant turns plus the ask-question options, because the choice the skill requires is offered through that tool rather than in prose.
  • The eval provider and shared harness already support force_skill_invocation, expose_ask_question, mock_ask_question_answers, and kickoff_text, so no harness changes were needed.

Note

Overview
Replaces the onboarding orchestrator with a quieter, fixed sequence: short kickoff (no roadmap table or upfront account question), repo-detected resume instead of LAUNCHDARKLY_ONBOARDING.md, work on launchdarkly-onboarding with uncommitted changes, then explore → SDK install → first flag with a live in-app banner reveal → optional MCP.

MCP moves to the end. Setup reaches the first flag via dashboard links when needed; mcp-configure and catalog copy now say MCP is offered only after the flag works. MCP docs emphasize the unified mcp/launchdarkly server, treat mcp/fm and mcp/aiconfigs as deprecated (migrate only after user consent), and probe tools before suggesting editor restart.

Removes nested first-flag/ and follow-through references (1.8-summary, 1.9-editor-rules); first-flag behavior lives in the parent skill. skills.json drops the first-flag skill entry and bumps onboarding to 0.3.0.

Adds evals/onboarding (kickoff voice, monorepo package choice, no MCP before create-flag, drift redirect) plus eval:onboarding / :single scripts and manifest registration; root and skill READMEs describe the new flow.

Remove first-flag/, references/1.8-summary.md, and references/1.9-editor-rules.md
(the v2 flow has no summary or editor-rules step) and repoint every reference to
the parent skill's Step 4.

Only suites whose source actually changed since their last recorded score were re-run. Soft-failing while we stabilise the baseline.

Drop the edge case claiming mcp/fm needs no migration, which contradicted the
adjacent deprecation prompt, and name the Cursor toggle after the server the
config actually writes.
