Claude Code Hook Development

The documentation covers input validation, path safety, variable quoting, timeouts, permission confirmation, and sensitive-file warnings, and recommends CLAUDE_PLUGIN_ROOT for portability. Deductions apply because examples send raw input to Slack, databases, and audit logs without consent, least-privilege guidance, redaction, rollback, or recovery procedures; an administrator bypass and predictable /tmp state files further weaken the security model.

The skill specifies events, input fields, exit codes, debugging methods, and a testing workflow; example scripts use set -euo pipefail and some empty-input checks. Deductions apply because static material does not prove key paths run successfully, and several examples depend on jq, the Claude Code runtime, external commands, or scripts not otherwise supplied; some output-format and parallel/sequential behavior claims may be inconsistent, while abnormal-input, timeout, and missing-dependency diagnostics are thin.

Trigger phrases, supported events, and use cases for command and prompt hooks are clearly described, covering validation, context loading, stop checks, and notifications. Deductions apply because non-fit scenarios, runtime-version boundaries, platform differences, and prompt-hook reliability limits are not clearly defined; there is no Chinese-language guidance or mainland-China reachability assessment, and external integrations may depend on network access.

The material has useful information architecture with overview, events, configuration formats, patterns, examples, script documentation, debugging, limitations, and workflow; the skill declares version 0.1.0, while the repository supplies README, LICENSE, and security-policy material. Deductions apply because the skill metadata does not declare a license, lacks a changelog, named maintenance responsibility, and explicit update path, and provides no compatibility matrix; some advanced examples present high-risk practices as copyable templates.

The skill provides reusable JSON configurations, shell examples, an event reference, migration guidance, and a testing workflow that can cover the core task of creating common Claude Code hooks. Deductions apply because static review cannot verify actual event semantics, outputs, or runtime behavior; users must supply plugin structure, dependencies, and environment details, and heuristic security policies still require substantial review and modification for complex cases.

The material includes concrete configurations, scripts, test commands, debug commands, and repository CI evidence, giving some claims an auditable basis. Deductions apply because the supplied files contain no real CI coverage for this skill's key paths or third-party execution evidence; the testing material is largely illustrative and does not cover prompt hooks, event compatibility, parallel behavior, or external integrations, so static verifiability remains limited.
