Lists multiple concrete actions: read, write, search, tag, query the Obsidian vault. Also mentions typed wrappers around the Obsidian CLI with version specificity (v1.12+) and 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 specifically, mentions the CLI tool, version requirement, and that Obsidian must be running. The emphatic 'ONLY correct way to interact with the vault' further reduces conflict risk by asserting exclusivity for vault operations.

The skill is extremely long and includes multiple composable subsystems (Agent Memory, Research Reports, Friction Self-Healing) that could each be separate files. There's significant verbosity in explaining workflows, tables of trigger signals, and extended examples. The 'Composing with Other Skills' section repeats patterns already shown. Much content (callout types, highlight syntax, property explanations) is standard Obsidian knowledge Claude already has.

The skill provides fully executable PowerShell commands with heredoc syntax, a comprehensive Python API quick reference with concrete method signatures and arguments, and copy-paste ready examples for every operation (create, read, append, search, memory saving, report saving). The CLI commands are specific and complete.

Multi-step workflows are clearly sequenced with explicit validation checkpoints. The self-healing workflow has numbered steps with decision points (P0/P1/P2 triage). The upgrade workflow has a clear 8-step sequence. Verification notes explicitly call out the need to follow up creates with reads. The deduplication workflow includes a search-before-create pattern with branching logic.

This is a monolithic wall of text with Agent Memory, Research Reports, Friction Self-Healing, Output Formatting Rules, Composing with Other Skills, and Upgrade workflows all inline. These are clearly separable concerns that should be in their own files with references from the main SKILL.md. No bundle files are provided, yet the content is far too long for a single file — it would benefit enormously from splitting into referenced sub-documents.
