markusdowne/handoff-integrity-check
Validate agent handoff packets and resume readiness using schema, freshness, and replay checks. Use when tasks pause/resume across sessions, agents, or humans — including when a user wants to continue where they left off, hand off to another agent, resume a previous task, or pick up an interrupted workflow. Includes explicit untrusted-content/prompt-injection guardrails for third-party inputs.

Discovery
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 well-crafted skill description that excels across all dimensions. It provides specific technical capabilities, includes natural trigger terms users would actually say, explicitly addresses both what and when, and occupies a clear niche that won't conflict with other skills. The description uses proper third-person voice throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Validate agent handoff packets', 'resume readiness', 'schema, freshness, and replay checks'. These are concrete, technical operations clearly describing what the skill does. | 3 / 3 |
Completeness | Clearly answers both what ('Validate agent handoff packets and resume readiness using schema, freshness, and replay checks') AND when ('Use when tasks pause/resume across sessions, agents, or humans') with explicit trigger scenarios listed. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'pause/resume', 'continue where they left off', 'hand off to another agent', 'resume a previous task', 'pick up an interrupted workflow'. These match how users naturally describe these scenarios. | 3 / 3 |
Distinctiveness Conflict Risk | Very specific niche around agent handoffs and session continuity. Terms like 'handoff packets', 'schema checks', 'replay checks' are distinct and unlikely to conflict with general task or workflow skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
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 high-quality skill that provides clear, actionable guidance for validating handoff packets. It excels at concrete examples (valid/invalid JSON, expected outputs), executable code snippets, and a well-structured workflow with explicit classification criteria. The untrusted content guardrails section adds valuable safety constraints without being verbose.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, providing only necessary information without explaining concepts Claude already knows. Every section serves a clear purpose with no padding or unnecessary context. | 3 / 3 |
Actionability | Provides fully executable Python code for freshness and token validation, concrete JSON examples for valid/invalid packets, and specific output format examples. Copy-paste ready throughout. | 3 / 3 |
Workflow Clarity | Clear 6-step workflow with explicit validation checkpoints, classification criteria, and recovery paths. The replay test provides a feedback loop, and the guardrails section adds safety constraints for edge cases. | 3 / 3 |
Progressive Disclosure | Well-organized sections with clear headers. Content is appropriately structured for a self-contained skill under 100 lines. No need for external references given the scope, and navigation is straightforward. | 3 / 3 |
Total | 12 / 12 Passed |
Validation
