Conciseness

Nearly every token carries non-obvious, hard-won knowledge (curl 403s regardless of UA, the rut-token requirement, aggressive rate limits, cookie-lapse recovery), but a few lines explain things Claude already knows — "-L follows redirects", "single-quote the URL so the shell doesn't eat &" — so it sits at 'efficient; minor instances of over-explanation' rather than 'every token earns its place'.

Actionability

Fully executable throughout: exact browser_navigate URLs with query parameters, copy-paste JS for the DDG href grab and JSON parsing, a shreddit-DOM scraping fallback, and a complete curl+jq command with temp-file and status-code handling — covering listings, threads, search, and fallback paths, which matches the 'fully executable, copy-paste ready, covers common cases' anchor.

Workflow Clarity

The two-step method is explicitly sequenced (DDG hop once per session, then direct .json) with real validation and feedback loops: try/catch that returns body text so a challenge page is detected and the hop is re-done, pkill recovery for 'Browser is already in use', and backoff guidance for 429/empty responses. This is the 'explicit validation steps; feedback loops for error recovery' anchor, not the level below with 'minor validation gaps'.

Progressive Disclosure

No bundle files exist and none are needed; the single file is organized into clear, well-labeled sections (primary method, JSON shapes, fallbacks, rate limiting). It is above the ~50-line simple-skill threshold at ~78 lines with all content inline, which fits 'good structure; most content appropriately placed; minor organization gaps' — the curl fallback block is the one candidate for trimming or offloading that keeps it from a top score.

Specificity

"Fetch content from Reddit via its JSON API using a browser session (DuckDuckGo-hop unlock)" names the domain and one concrete, method-specific action, but only one capability is stated (fetch) with no listing/search/thread distinctions — matching the '1-2 concrete actions, not comprehensive' anchor rather than the 'several specific actions' anchor above.

Completeness

The what is explicit ("Fetch content from Reddit via its JSON API using a browser session") and the when is explicit with concrete trigger phrases ("Use when accessing Reddit URLs, researching topics on Reddit, or when Reddit returns 403/blocked errors"), cleanly matching the anchor requiring both with concrete triggers.

Trigger Term Quality

"Reddit URLs", "researching topics on Reddit", and "when Reddit returns 403/blocked errors" are natural phrases users would actually say, including an error-state trigger; common variations like "subreddit", "posts", "threads", or "scrape" are missing, so it fits 'good keyword coverage; a few natural terms missing' rather than the comprehensive anchor.

Distinctiveness Conflict Risk

It carves a clear Reddit-only niche with distinct triggers, including the unique "Reddit returns 403/blocked errors" condition no other skill would claim, giving minimal conflict risk; it is well above the 'minor overlap risk' anchor.
