Conciseness

The body is command-dense and mostly lean, but includes concept primers Claude already knows: "DNS-over-HTTPS encrypts your DNS queries so your ISP cannot see what sites you resolve" and the "How Pi-hole Works" walkthrough. These are minor over-explanations that could be trimmed, matching the 4 anchor rather than the 5 anchor's every-token-earns-its-place.

Actionability

Concrete, mostly copy-paste-ready guidance: a full docker-compose.yml, dhcpcd.conf edits, specific blocklist URLs, and a real troubleshooting CLI section. Falls short of the 5 anchor because of the "<pinned-release-tag>"/"<pinned-version>" placeholders and "Verify the checksum/signature from Cloudflare's release notes" giving no verification command; well above the 3 anchor since the code is genuinely executable, not pseudocode.

Workflow Clarity

Sequences are clear and ordered (static IP → install; disable router DHCP → enable Pi-hole DHCP; DoH proxy → repoint upstream), and verification commands exist ("pihole status", "dig @192.168.3.2 google.com"). A minor validation gap keeps it at 4: no explicit checkpoint confirming Pi-hole resolves correctly before pointing the whole network at it — the network-wide cutover step lacks a validate-before-proceed gate.

Progressive Disclosure

No bundle files exist, so all content is a single ~270-line file — but it is well-sectioned with clear headers (Installation, Blocklist Management, DoH, Local DNS, Troubleshooting, Anti-Patterns) and easy navigation. Matches the 4 anchor: good structure with minor organization gaps; the DoH setup and blocklist catalog are long enough to be one-level-deep reference files. Not 5 because there is no overview-plus-references split, and not 3 because nothing is buried or nested.

Specificity

"Pi-hole installation, blocklist management, DNS-over-HTTPS setup, DHCP integration, local DNS records, and troubleshooting broken DNS resolution" lists six concrete, distinct capabilities with comprehensive coverage of the skill's scope. No notable coverage gaps, so it sits at the top anchor rather than the 4 anchor's "minor gaps".

Completeness

Explicitly answers both: "what" (six named capabilities) and "when" ("Use when the task explicitly involves Pi-hole — installing it, managing blocklists, configuring DoH or DHCP, adding local DNS records, or diagnosing DNS resolution with Pi-hole in the path"). The trigger clause is explicit and enumerated, matching the 5 anchor exactly rather than the 4 anchor's "when could be more explicit".

Trigger Term Quality

Good natural-term coverage: "Pi-hole", "blocklists", "DNS-over-HTTPS" and "DoH", "DHCP", "DNS resolution", "home network", "local DNS records". A few natural terms are missing — most notably the "ad blocking" / "block ads" phrasing many users would use for Pi-hole — which keeps it below the 5 anchor's synonym-and-extension completeness.

Distinctiveness Conflict Risk

"Use when the task explicitly involves Pi-hole" gates triggering on a unique product name with a clear niche (home-network DNS). Minimal conflict risk with generic DNS, networking, or Docker skills, matching the 5 anchor rather than the 4 anchor's "minor overlap risk".
