/install resend-cli
Description
Send and manage emails via the Resend CLI. Covers sending, domains, contacts, segments, broadcasts, templates, topics, webhooks, and API keys.
Usage Guidance
This skill appears to be what it says: a helper for the official Resend CLI. Before installing, 1) only provide a Resend API key with the minimal scope needed (use a domain-scoped sending_access key for automation) and avoid giving full-access keys to agents; 2) install the CLI from a trusted source (brew or npm) and verify the project repository if you need extra assurance; 3) remember that the CLI will read local files you pass (HTML, attachments, JSON batches) and the credentials file (~/.config/resend/credentials.json) — protect those files with appropriate permissions and rotation; 4) because the agent can invoke the skill, prevent accidental or automated mass-sends by limiting the key scope and by controlling when/how the agent is allowed to run commands that send email.
Capability Analysis
Type: OpenClaw Skill
Name: resend-cli
Version: 1.0.5
The skill bundle provides a legitimate and comprehensive interface for the official Resend CLI (resend-cli). It includes standard commands for email management, domain verification, and API key handling, along with appropriate 'Agent Usage Rules' that ensure the AI agent uses non-interactive flags like --json and --yes. No evidence of data exfiltration, malicious execution, or prompt injection was found in SKILL.md or _meta.json.
Capability Assessment
Purpose & Capability
Name/description match the runtime instructions: the doc instructs use of the 'resend' CLI, sending/listing/managing emails, domains, contacts, broadcasts, templates, webhooks and API keys. Declared primaryEnv (RESEND_API_KEY), required binary ('resend') and credentials path (~/.config/resend/credentials.json) are what the official CLI needs; nothing unrelated is requested.
Instruction Scope
Instructions are narrowly scoped to running the Resend CLI: example commands for sending, listing, domain management, etc. They reference local files (email.html, attachments, emails.json) and the CLI credential file, which is expected for this use case. There are no instructions to read unrelated system files or to exfiltrate data to unknown endpoints.
Install Mechanism
This is an instruction-only skill (no install spec in the registry). The README recommends installing via brew or npm — both are normal, low-risk distribution channels for a CLI. No arbitrary download URLs or extract/install steps are present in the skill metadata.
Credentials
Only RESEND_API_KEY and the CLI binary/credential file are referenced. The skill even suggests using a domain-scoped 'sending_access' key for automation (least privilege). No unrelated secrets or multiple external credentials are requested.
Persistence & Privilege
Skill is not always-enabled (always:false) and does not request system-wide privileges or to modify other skills. Note: model invocation is permitted by default (disable-model-invocation:false), so an agent with this skill could be used to send emails if given the API key — this is expected but worth considering operationally.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install resend-cli - After installation, invoke the skill by name or use
/resend-cli - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.5
Shorter description
v1.0.4
Shorter description for better UI display
v1.0.3
Fix: flattened metadata structure for ClawHub runtime requirements parsing. Added emoji.
v1.0.2
Fix: added homepage, source, license to frontmatter for provenance verification. Metadata block declares primaryEnv, requires (bins + env), configPaths, and brew install method.
v1.0.1
Fix: added metadata (primaryEnv, requires, configPaths, install) for security scan compliance. Recommend brew install over curl|bash. Added domain-scoped key guidance.
v1.0.0
Initial release — full Resend CLI coverage: emails, domains, contacts, segments, broadcasts, templates, topics, webhooks, API keys
