observability-logging

Logs sessions, tracks activity, records delegation decisions, and stores review/dispute outcomes as NDJSON audit trails. Use when logging session activity, tracking work, recording decisions, building audit trails, capturing delegation history, or running pre-response verification checklists. Trigger terms: log, track activity, audit trail, session record, delegation log, NDJSON

Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a well-crafted skill that is concise, fully actionable, and clearly structured. It provides executable CLI commands for every event type, includes explicit validation steps (tail verification and pre-response checklist), and appropriately delegates detailed schema documentation to referenced files. The hard gate framing and checklist create strong guardrails for compliance.

DimensionReasoningScore

Conciseness

Every section is lean and purposeful. No unnecessary explanations of what NDJSON is or how logging works conceptually. The table, CLI examples, and checklist all earn their tokens. The skill assumes Claude understands the concepts and jumps straight to executable commands.

3 / 3

Actionability

Every event type has a fully executable, copy-paste-ready CLI command with realistic arguments. The verification step (`tail -1`) is concrete. The pre-response checklist provides specific, actionable items rather than vague guidance.

3 / 3

Workflow Clarity

The workflow is clear: log events using the CLI during the session, verify the append with `tail -1`, then run the pre-response checklist before responding. The hard gate at the top and the STOP checklist at the bottom create explicit validation checkpoints. The 'fix any missing log NOW' instruction provides a feedback loop for error recovery.

3 / 3

Progressive Disclosure

The SKILL.md serves as a concise overview with clear one-level-deep references: `.opencastle/logs/README.md` for full schema, `../../snippets/base-output-contract.md` for the output contract. Content is appropriately split — detailed schema lives elsewhere while actionable commands are inline.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong skill description that clearly articulates specific capabilities (session logging, activity tracking, delegation decision recording, NDJSON audit trails), provides explicit 'Use when' guidance with multiple trigger scenarios, and includes a dedicated trigger terms list. The description is well-structured, uses third person voice correctly, and occupies a distinct niche that minimizes conflict risk with other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'Logs sessions, tracks activity, records delegation decisions, and stores review/dispute outcomes as NDJSON audit trails.' These are distinct, concrete operations with a specific output format (NDJSON).

3 / 3

Completeness

Clearly answers both 'what' (logs sessions, tracks activity, records delegation decisions, stores review/dispute outcomes as NDJSON) and 'when' with an explicit 'Use when...' clause listing multiple trigger scenarios plus a dedicated trigger terms section.

3 / 3

Trigger Term Quality

Includes a dedicated trigger terms list with natural keywords users would say: 'log, track activity, audit trail, session record, delegation log, NDJSON.' The 'Use when...' clause also adds variations like 'logging session activity,' 'recording decisions,' and 'pre-response verification checklists.'

3 / 3

Distinctiveness Conflict Risk

The combination of NDJSON audit trails, delegation decisions, session logging, and review/dispute outcomes creates a very specific niche. Terms like 'delegation log,' 'NDJSON,' and 'audit trail' are distinctive enough to avoid conflicts with general logging or tracking skills.
