Conciseness

The body is dense operational guidance (command blocks, filter/field tables, troubleshooting rows) with almost no padding or explanation of concepts Claude already knows. It sits at anchor 4 rather than 5 because the 'Codex Notes' section largely repeats Phase 0's finder workflow and example commands, and the Subagent/Child Sessions storage table could be trimmed or delegated to references.

Actionability

Commands are fully executable and copy-paste ready ('python3 scripts/find-agent-sessions.py list --limit 20', 'find --query ... --include-subagents --workers 64', 'read <session-id>'), with concrete query-lane expansion heuristics and per-problem troubleshooting fixes. Not anchor 4 because the examples cover the common cases (fuzzy recall, cross-platform search, subagent inclusion) completely.

Workflow Clarity

The Phase 0 steps form a clear sequence: route to the platform reference, run the broad finder with expanded query lanes, split parallel lanes when needed, read via detail_hint, then 'Verify by opening raw transcripts for claims'. Explicit validation checkpoints (detail_hint before ad hoc digging, raw-path verification) plus a troubleshooting table for error recovery match anchor 5; this is a read-only search skill so the destructive-batch cap does not apply.

Progressive Disclosure

SKILL.md is an overview with well-signaled, one-level-deep references: the platform router table maps each platform to a specific references/*.md file, all of which exist in the bundle, and per-platform storage details are correctly deferred to references and the script. Navigation is easy and nothing is nested two levels deep.

Specificity

'Finds, reads, and reconstructs coding-agent sessions across Codex, Claude, OpenCode, OMO/Senpi, and other local agent logs' names three concrete actions plus the full platform domain. This matches anchor 4 ('lists several specific actions; minor gaps') rather than 5, whose anchor example enumerates four distinct actions with no coverage gaps; narrower verbs like listing or filtering sessions are only implied.

Completeness

It explicitly answers both questions: the what ('Finds, reads, and reconstructs coding-agent sessions across [platforms] and other local agent logs') and the when ('Use when asked to find or search past sessions, transcripts, or subagent runs, or to recover what an earlier session did'). This is the anchor-5 pattern — clear what plus concrete trigger phrases — not anchor 4, whose 'when' is shorter and less specific.

Trigger Term Quality

'find or search past sessions, transcripts, or subagent runs, or to recover what an earlier session did' covers the natural phrases a user would actually say, with synonyms (find/search, sessions/transcripts/subagent runs) and product names (Codex, Claude, OpenCode, OMO/Senpi) users would mention by name. This matches the comprehensive-synonyms anchor, not anchor 4 which requires missing natural terms.

Distinctiveness Conflict Risk

The niche is unambiguous — local coding-agent session/transcript logs for named agent products — with triggers ('past sessions, transcripts, subagent runs') that would not plausibly route to a generic memory or document skill. Minimal conflict risk matches anchor 5.
