Conciseness

Dense tables and one-line rules throughout ("Read the matching doc page before writing code; do not guess SDK signatures"; "Request the minimum; high-risk operations are flagged to the confirming member") with zero padding and no explanations of concepts Claude already knows. Not 4: there is no over-explanation to trim — every token earns its place.

Actionability

Copy-paste-ready command block (lbp init → lbp run → lbp build → lbp login && lbp publish, each with inline comments), concrete call signatures with real argument names (call_platform_api(bot_uuid, action, params)), an explicit return-shape contract ("{"ok": True, "result": ...}"), and a concrete catalog command (python plugins/scripts/check_catalog.py --write). Not 4: the executable guidance is complete rather than having minor gaps; SDK signatures are deliberately and appropriately delegated to canonical docs.

Workflow Clarity

The Workflow section is a clearly ordered sequence (scaffold → configure debug env → attach/debug → build → publish) with per-step comments, and API guidance includes error-recovery rules ("check `ok`. Treat `permission_denied` as expected"). Not 5: the publish path lacks an explicit validation checkpoint before upload (e.g., verify the built .lbpkg or test results before lbp publish), and debugging as a checkpoint is implicit rather than an explicit gate.

Progressive Disclosure

The body is a lean overview; two one-level-deep references (references/sdk-pitfalls.md, references/testing.md — both verified as real files with substantive content) are clearly signaled in a References section describing what each contains. Not 4: navigation is unambiguous and content is appropriately split between overview and references.

Specificity

"Develop, debug, test, and publish LangBot plugins" plus enumerated concrete actions — choosing component types (all eight named: EventListener, Command, Tool, Runner, KnowledgeEngine, KnowledgeRetriever, Parser, Page), calling Workspace/platform/execution APIs, declaring permissions, debugging with lbp run, publishing to LangBot Space — giving comprehensive, concrete coverage of the plugin lifecycle. Not 4: coverage is comprehensive with named entities rather than having minor gaps.

Completeness

Explicitly answers both: what ("Develop, debug, test, and publish LangBot plugins") and when ("Use when creating or fixing a LangBot plugin ... or publishing to LangBot Space") with a concrete trigger list. Not 4: the when-clause is multi-condition and concrete, matching the anchor-5 pattern rather than merely present.

Trigger Term Quality

Explicit triggers ("langbot plugin", "lbp", "plugin permissions", "workspace api", "call_platform_api", "plugin debug") are natural phrases a user would say in this domain. Not 5: a few natural terms are missing, e.g. "plugin publish", "LangBot Space", or artifact synonyms like ".lbpkg".

Distinctiveness Conflict Risk

Clear product-specific niche (LangBot, lbp, LangBot Space) with distinct triggers; minimal conflict risk with other skills. Not 4: no plausible overlap with a closely related skill.
