Lists multiple concrete actions: read, write, search, tag, query. Also mentions typed wrappers around Obsidian CLI with version specificity (v1.12+), and notes the requirement that Obsidian must be running.

Clearly answers both 'what' (composable Obsidian vault operations via CLI — read, write, search, tag, query) and 'when' (explicit 'Use when' clause with specific trigger phrases and a general rule about any vault operation).

Excellent coverage of natural trigger terms users would say: 'save to vault', 'obsidian', 'research note', 'daily note', 'tag', 'summarize and save', plus the general 'vault operation'. These are realistic phrases users would naturally use.

Highly distinctive — targets Obsidian vault operations specifically, with clear niche triggers like 'obsidian', 'vault', 'daily note'. The emphatic statement 'This is the ONLY correct way to interact with the vault' further reduces conflict risk by asserting exclusivity. Unlikely to overlap with non-Obsidian skills.

The skill is extremely long and verbose. It includes extensive sections on Agent Memory, Research Reports, Friction Self-Healing, and Composing with Other Skills that go well beyond the core vault operations. Many sections explain workflows and concepts Claude could infer. The 'What NOT to do' section, Unicode troubleshooting, and detailed self-healing examples add significant token overhead.

The skill provides fully executable PowerShell commands with heredoc syntax, a comprehensive Python API quick reference with concrete method signatures and examples, and copy-paste ready patterns for every operation (create, read, append, search, etc.).

Multi-step workflows include explicit validation checkpoints: the verification notes section instructs to verify creates with follow-up reads, the deduplication section requires searching before creating, the self-healing workflow has a clear numbered sequence with priority-based decision points, and the upgrade workflow has a clear 8-step process with explicit save/snapshot steps.

The skill is a monolithic wall of text with no references to separate files for the extensive Agent Memory, Research Reports, or Friction Self-Healing sections. These composable patterns could each be their own referenced documents. The Quick Reference alone is ~80 lines that could be in a separate API reference file. No bundle files are provided despite the content clearly warranting them.
