Conciseness

Mostly efficient template/reference material, but it spends tokens on concepts Claude already knows (the Key Concepts table defining Target/Package/Label/Rule/Aspect, the standard directory tree) and pins time-sensitive versions inline (rules_js-1.34.0, node 20.9.0, rules_python-0.27.0) outside any deprecation section. This fits anchor 3 — some unnecessary explanation that could be trimmed — rather than 4, given the guideline penalty on version numbers and re-explained basics.

Actionability

Seven concrete, mostly executable templates (WORKSPACE, .bazelrc, BUILD files, custom rule, query commands, platform/toolchain defs) with minor gaps: sha256 = "..." placeholders, and Template 3 loads @aspect_rules_ts which Template 1 never declares. That keeps it at anchor 4 (mostly executable, minor gaps) rather than 5 (fully copy-paste ready), and well above anchor 3's pseudocode level.

Workflow Clarity

The skill is organized as a template cookbook rather than a sequenced process: tasks promised in "When to Use" (migration, debugging build issues, optimizing build times) have no ordered steps, and the Performance section lists profiling commands without a profile → diagnose → fix → re-measure loop or any validation checkpoints (e.g. verifying cache hit rates or that a config change didn't break the build). Anchor 3 fits — material is structured but checkpoints and explicit sequences are missing; not 2 because each template is internally coherent and self-contained.

Progressive Disclosure

There is no bundle (no references/, scripts/, or assets/ directories) and roughly 300 lines of templates are inlined in SKILL.md, where the rubric expects them split into one-level-deep reference files. Section headers exist and navigation within the file is reasonable, so this is anchor 3 (some structure, but content that should be separate is inline) rather than 2 (minimal structure) — the sections are clearly labeled and each template is easy to locate.

Specificity

The only stated capability is "Optimize Bazel builds for large-scale monorepos" — one concrete action on a named domain. The "Use when" clause lists scenarios (configuring, remote execution) rather than additional capabilities, so coverage is not comprehensive (no caching, custom rules, or migration mentioned), matching anchor 3; not 4 because it does not list several distinct actions, and not 2 because the domain and action are concrete rather than generic.

Completeness

Explicitly answers both: what ("Optimize Bazel builds for large-scale monorepos") and when ("Use when configuring Bazel, implementing remote execution, or optimizing build performance"). The when-clause is present but partly redundant with the what and omits triggers the body itself covers (custom rules, migration, debugging), so it fits anchor 4 rather than 5, and well above anchor 3 (which requires a missing or only implied when).

Trigger Term Quality

Includes natural terms users would say — "Bazel", "build performance", "remote execution", "monorepos", "enterprise codebases". A few common variations are missing ("build times", "slow builds", "remote caching", "CI"), matching anchor 4 rather than 5, and clearly above anchor 3's partial keyword coverage.

Distinctiveness Conflict Risk

"Bazel" carves out a clear niche with distinct, tool-specific triggers (remote execution, monorepo builds); it is unlikely to fire for non-Bazel build tools or other skills, matching anchor 5.
