Conciseness

Most content is repo-specific fact Claude cannot know (file paths, version mappings, build commands), but the LF-2.2 conclusion is repeated across four sections ('Root Cause (Verified)', 'Key insight', 'Building with LF 2.2', 'Fully Open-Source LF 2.2 Build'), and dated verification logs ('Verified Results (2025-12-24)', snapshot hashes, May/Oct 2025 dates) are time-sensitive detail not quarantined in an old-patterns section. Mostly efficient but could be tightened, matching anchor 3.

Actionability

Concrete executable guidance throughout: 'sbt "community/app/assembly"', 'nix-shell -p daml-sdk --run "daml build -p daml/splice-amulet"', perl one-liners, and exact file edits with code blocks. Minor gaps keep it below anchor 5: the assembly target is inconsistent ('community/app/assembly' vs 'canton-community-app/assembly') and 'perl -pi -e ... **/daml.yaml' requires globstar to recurse.

Workflow Clarity

The LF-2.2 migration is a clear numbered 5-step sequence, the expected output hashes ('canton-builtin-admin-workflow-ping-3.4.9-fbeb863dab36da66d99...') act as verification targets, and the Troubleshooting section gives cause/check/fix recovery for the three common failures. It misses anchor 5 because no explicit post-build validation step (e.g., compare produced package IDs against the listed hashes) is embedded in the workflow itself.

Progressive Disclosure

No bundle files exist, and the single SKILL.md is well-sectioned (hierarchy, repository details, version mapping, build, troubleshooting, key files table) making navigation easy. Some deep reference material — LanguageVersion.scala source excerpts, dated verified-results logs, the enterprise/community feature table — reads like content that belongs in separate reference files, matching anchor 4 rather than 5.

Specificity

The description names the domain clearly ('Canton Network, DAML, and Splice repository knowledge') and cites concrete problem areas ('LF version compatibility, or package ID mismatches'), but the 'what' is the generic action 'knowledge' rather than listed concrete actions. It sits above anchor 2 (domain named but actions minimal) and below anchor 4 (several specific actions listed).

Completeness

Both 'what' ('Canton Network, DAML, and Splice repository knowledge') and 'when' ('Use when working with... Triggers on...') are present, with the when clause explicit and concrete. The what clause is vaguer than anchor 5's clearly enumerated capabilities, matching anchor 4 ('both what and when; when could be more explicit') inverted — here the what could be more explicit.

Trigger Term Quality

The explicit trigger list ('Triggers on Canton, DAML, Splice, decentralized-canton-sync, or LF version queries') plus 'Use when working with Canton participants, DAML smart contracts, Splice applications' gives good natural-term coverage. A few natural variants users might say (DAR, Canton Coin, daml-lf) are missing, so it falls just short of anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

A clear niche with distinct triggers: Canton, DAML, and Splice are unambiguous project names unlikely to collide with other skills, and the description enumerates them as literal trigger terms. Minimal conflict risk.
