Conciseness

Lean throughout: the only explanatory passages (the two-id trap, harness_session_id vs id) are domain knowledge Claude does not already have, and there is no padding or restatement of basic concepts.

Actionability

Provides copy-paste-ready commands for every common case — Claude Code lookup, any-harness footprint matching, `sessions get` verification, `whoami --json`, and explicit URL construction — plus a Quick reference table indexing them.

Workflow Clarity

A numbered workflow (resolve → verify → build link) with an explicit validation checkpoint (`sessions get`) and clear fallback branches for zero/multiple candidates; the operation is non-destructive so no batch cap applies.

Progressive Disclosure

No bundle files exist and none are needed; the body is organized into well-labeled sections (Overview, the trap, workflow, turn linking, quick reference, common mistakes, prerequisites) making navigation easy within a single file.

Specificity

Lists multiple concrete actions — "identify or link the Paper recording of its own running session", "link a known session or matched turn", "Resolves the tapes session id with `paperctl sessions` and builds the console URL" — covering the full linking workflow comprehensively.

Completeness

Explicitly answers both what (resolves the tapes session id and builds the console URL) and when ("Use when an agent must identify or link the Paper recording...") with concrete trigger phrases.

Trigger Term Quality

Embeds natural user phrases users would actually say — "what's my session id", "link to this session", "share this session", "is this being recorded", "open this run in the console", "paper session link" — with strong synonym coverage.

Distinctiveness Conflict Risk

Occupies a clear niche (session linking by identity) and explicitly carves it off from the `search` skill, leaving minimal overlap risk with neighboring skills.
