Conciseness

Noticeably verbose across several padded sections: the 'Mental Model' ocean-wave metaphor ('Paddling in', 'The shoulder', 'The close-out', 'Wipe-out territory'), tagline prose ('No wipeouts. No zombie sessions.'), the pre-commit anchor check explained in full under 'The Monitoring Paradox' and then re-summarized in 'Riding the Wave', and the pipeline/task-type table duplicated in both 'When to Use the Full Pipeline' and 'Pipeline position'. The 'Handoffs become learning signals' digression adds further padding. Not 'mostly efficient' (anchor 3) — roughly a third of the file could be cut without losing actionable content.

Actionability

Fully executable throughout: copy-paste install commands ('gh skill install pskoett/pskoett-skills context-surfing'), 'entire status 2>/dev/null' detection, a complete handoff file template with named sections, hook JSON for .claude/settings.json with concrete path variants, Codex hook config, the fallback 'ls .context-surfing/handoff-*.md' command, the 'touch <handoff-path>.consumed' marker, and a scripted escalation message. Even the judgment-based drift signals are given as concrete, checkable examples ('it depends', 'could be', 'might want to consider').

Workflow Clarity

Every multi-step process is explicitly sequenced with validation checkpoints and feedback loops: Activation (numbered anchor-loading list), Recovery Protocol (Steps 1–2 with branch outcomes, 'at most one local re-anchor and one cold-context check' limits), Exit Protocol (Steps 1–3), next-session procedure (numbered 1–6), and Session Close. The pre-commit anchor check ('quote verbatim → state pending action → verify trace-back → on failure enter Recovery Protocol') is an explicit validation gate before side-effecting actions, and the cold-context subagent escalation path is a genuine error-recovery loop.

Progressive Disclosure

In-file structure is good — clear section headers, and the one bundle reference (scripts/handoff-checker.sh) is real, correctly pathed, and clearly signaled. But ~420 lines are monolithic: the handoff file template, Hook Integration setup, and Interoperability sections are clearly separable reference-file material, and no references/ directory is used at all. Anchor 3 ('content that should be separate is inline') fits better than anchor 4 given the length and the multiple separable chunks.

Specificity

Lists several specific actions/mechanisms — 'Monitors context window health', 'Uses bounded external anchors', 'one cold-context review when self-recovery is uncertain', 'a clean handoff on real drift'. Not 5: phrases like 'bounded external anchors' describe mechanisms abstractly and coverage has minor gaps (no mention of the pre-commit anchor check, the skill's primary gate).

Completeness

Clearly answers both questions: the 'what' is explicit (monitor context window health via external anchors, cold-context review, clean handoff) and the 'when' is explicit and qualified ('during large, long-running, multi-session, or explicitly context-sensitive work') — plus an explicit anti-trigger ('Do not auto-activate merely because a medium task has an intent frame and plan'). Anchor 4's 'when could be more explicit or specific' does not fit: the when is stated outright with multiple concrete qualifiers.

Trigger Term Quality

Good natural-term coverage: 'context window', 'large, long-running, multi-session', 'drift', 'handoff'. Not 5: jargon-heavy phrases ('bounded external anchors', 'cold-context review') are not things users would say, and common synonyms a user might actually use ('context pressure', 'session degradation', 'long task', 'compact/compaction') are missing.

Distinctiveness Conflict Risk

Clear niche — context-quality drift (hallucination, contradiction, coherence loss) — explicitly separated from adjacent lifecycle skills, and the closing anti-trigger clause ('Do not auto-activate merely because a medium task has an intent frame and plan') actively prevents misfires on the intent-framed-agent/plan-interview skills it most overlaps with.
