Conciseness

Every section is skill-specific with no explanation of concepts Claude already knows, but guidance is noticeably duplicated: done/ handling appears in Philosophy ("Done means done"), Phase 1, and two separate anti-patterns, and the AskUserQuestion guard appears both as a standalone CRITICAL section and as anti-pattern #3 with the same WHY. This fits the level-3 anchor (mostly efficient but could be tightened); level 4 would require the duplication to be only minor.

Actionability

Guidance is fully executable: a copy-paste Bash discovery command (ls -t .context/session/CONTEXT-*llm.md ...), a concrete parallel-Read plan with exact file paths for --full, a good/bad grep verification snippet, exact error messages via references/reference.md, and a worked resume-report example covering the default, named-stream, and --full cases. This matches the level-5 anchor (copy-paste ready, common cases covered).

Workflow Clarity

The three phases are clearly sequenced with explicit conditionals (done/ fallback, AskUserQuestion on multiple streams) and a real feedback loop for the empty-answers bug. However, the stream-header verification checkpoint lives in Anti-Patterns rather than being an explicit step in the workflow sequence itself, which is the minor validation gap of the level-4 anchor; level 5 would embed the validate-and-confirm step directly in the phase flow.

Progressive Disclosure

The body stays at overview/workflow level and externalizes section mapping, report layout, error messages, and formatting rules to references/reference.md — a real bundle file that exists — signaled twice (inline in Phase 3 and in a closing References table with a When-to-Use column) and exactly one level deep. This matches the level-5 anchor (clear overview, well-signaled one-level-deep references, easy navigation).

Specificity

"Resume session from CONTEXT-llm.md" names the domain and one concrete action anchored to a specific file, but the description lists no further capabilities (e.g., named streams, --full resource expansion), so coverage is not comprehensive. It is more concrete than the level-2 anchor ("Processes PDF files"-style generic action) but does not list the several specific actions the level-4 anchor requires.

Completeness

Both questions are explicitly answered: what ("Resume session from CONTEXT-llm.md") and when ("Use when resuming work, loading saved context, continuing a previous session. Triggers include..."), with concrete trigger phrases. This is a direct match for the level-5 anchor; level 4 would require the 'when' to be less explicit or specific.

Trigger Term Quality

The description gives both implicit triggers ("resuming work", "loading saved context", "continuing a previous session") and explicit quoted ones ("load context", "resume session", "continue where I left off"), covering the natural synonyms a user would say, plus the concrete filename. This matches the level-5 anchor (comprehensive natural terms including synonyms); level 4 would require a few natural terms to be missing, which is not the case.

Distinctiveness Conflict Risk

The niche (loading saved session context from CONTEXT-*.md files) is distinct with mostly dedicated triggers, but "resume session" is a common phrase users might say when they simply want to continue working, and closely related sibling skills (save-context, list-contexts per references/reference.md) create minor overlap risk. This fits the level-4 anchor (mostly distinct, minor overlap with closely related skills) rather than level 5's minimal-conflict clear niche.
