Conciseness

The body is lean and command-first with no concept explanations, but the opening paragraph ("AFS is a workspace system for agents, backed by Redis. Use it when you want a durable workspace that still feels like normal files and directories...") restates the frontmatter description, and a few Key Points ("Redis is the source of truth", "Create checkpoints explicitly") overlap other sections. Anchor 4 (efficient, minor trimming possible) fits; anchor 5 would require every token to earn its place with zero redundancy.

Actionability

Every section gives copy-paste-ready commands covering the common cases: "./afs ws create my-project", "./afs ws mount my-project ~/my-project", "./afs fs grep --workspace my-project 'TODO auth'", "./afs cp create/restore", "./afs ws fork", including flag variants ("--path /src -E 'timeout|retry'"). This matches the anchor-5 example of fully executable commands covering common cases.

Workflow Clarity

Each flow has a clear sequence with explicit verification commands ("./afs ws list # verify the workspace exists", "./afs status", "./afs cp list # confirm the restore completed"), so the destructive restore operation is validated and the cap-at-3 rule does not apply. However there are no error-recovery feedback loops (no guidance on what to do when a verify step fails), which keeps it below anchor 5.

Progressive Disclosure

The body is a concise overview with well-labeled, one-level-deep pointers ("docs/guides/agent-filesystem.md — agent-facing usage guide", "docs/reference/cli.md — full CLI command reference", "docs/reference/mcp.md — MCP tool reference"), matching the anchor-5 pattern of well-signaled references. It falls to 4 because the referenced paths sit outside the skill bundle (no references/ directory exists, so the paths cannot be verified as real bundle files) — a minor organization gap.

Specificity

It lists five concrete actions — "Creates Redis-backed workspaces, checkpoints and restores agent state, mounts shared filesystems locally, searches workspace contents, and forks workspaces for parallel work" — which is comprehensive coverage of the skill's capabilities, matching the anchor-5 example. Anchor 4 requires minor gaps in coverage; none are evident.

Completeness

It explicitly answers both questions: the what is "Creates Redis-backed workspaces, checkpoints and restores agent state, mounts shared filesystems locally, searches workspace contents, and forks workspaces" and the when is the leading "Use when agents need persistent shared storage, when saving or restoring workspace state, or when coordinating file access across multiple agents and machines" — three concrete trigger clauses, matching the anchor-5 example structure exactly.

Trigger Term Quality

Good natural-phrase coverage: "persistent shared storage", "saving or restoring workspace state", "coordinating file access", "multiple agents and machines", "checkpoints", "forks workspaces for parallel work". It falls short of anchor 5 because common synonyms users might say — e.g., "snapshot", "backup", "share files between agents", "resume work" — are absent.

Distinctiveness Conflict Risk

It carves a clear niche (Redis-backed agent workspaces with checkpoints and forks) with triggers ("persistent shared storage", "coordinating file access across multiple agents and machines") that are unlikely to fire for unrelated skills, matching anchor 5's "clear niche with distinct triggers; minimal conflict risk".
