Install via the Printing Press installer: ```bash npx -y @mvanhorn/printing-press-library install resend --cli-only ``` 2. Verify: `resend-pp-cli --version` 3. Ensure `$GOPATH/bin` (or `$HOME/go/bin`) is on `$PATH`. If the `npx` install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.3 or newer): ```bash go install github.com/mvanhorn/printing-press-library/library/productivity/resend/cmd/resend-pp-cli@latest ``` If `--version` reports "command not found" after install, the install step did not put the binary on `$PATH`. Do not proceed with skill commands until verification succeeds. ## When to Use This CLI Use this CLI when an agent needs to answer cross-resource questions about a Resend account that the dashboard or SDK cannot answer in one call — what did we send to a specific recipient, which audiences is a contact in, how does broadcast performance trend over time, what's the 7-day bounce rate. Stick with `npx resend send` for one-shot transactional sends or with React Email for templates; this CLI is the agent-facing companion, not a replacement. ## Unique Capabilities These capabilities aren't available in any other tool for this API. ### Cross-resource queries over local state - **`emails to`** — Every email sent to a single recipient address, with delivery status and timestamps, ordered newest-first. _Reach for this when an agent needs to reconstruct what a single user has received — support tickets, GDPR exports, dispute investigations._ ```bash resend-pp-cli emails to --json --select id,subject,status,sent_at ``` - **`emails timeline`** — Collapsed event chain for a single email: sent → delivered → opened → clicked → bounced, in one ordered table. _Use when debugging 'why didn't this arrive?' — one command shows whether it was sent, delivered, opened, or bounced and when._ ```bash resend-pp-cli emails timeline 4ef9a417-d4ff-4ec5-9af2-c80a4d5d2c1f --json ``` - **`audiences inventory`** — Per-audience rollup: contact count, unsubscribed count, last-broadcast timestamp, recent open-rate. _Use before planning a campaign — quickly see which audiences are healthy and recently engaged._ ```bash resend-pp-cli audiences inventory --json ``` - **`contacts where`** — Find every audience, segment, and topic a contact (by email or name) belongs to in one query. _Use when triaging unsubscribe requests, GDPR deletions, or 'why is bob getting this email?'._ ```bash resend-pp-cli contacts where --json --select audience_name,subscribed ``` ### Aggregate analytics from local store - **`broadcasts performance`** — Open / click / bounce rate across all broadcasts, sortable; not limited to a single broadcast or 30-day window. _Use to compare campaign performance across the lifetime of the account._ ```bash resend-pp-cli broadcasts performance --json --select broadcasts,count,status ``` - **`domains health`** — Verification + DKIM/SPF/DMARC status across every domain in one table, flags missing or unverified records. _Use on call-out / deliverability incidents to confirm all sending domains are fully verified._ ```bash resend-pp-cli domains health --json ``` - **`deliverability summary`** — Bounce rate, complaint rate, and suppression count over a rolling window (default 7d) computed from local event data. _Use weekly to monitor IP/domain reputation trends before they cause deliverability incidents._ ```bash resend-pp-cli deliverability summary --window 7d --json ``` ### Operational hygiene - **`api-keys rotation`** — API keys sorted by age + last-used timestamp (joined from logs); flags stale keys older than N days. _Use during quarterly security reviews — find unused keys that should be rotated or revoked._ ```bash resend-pp-cli api-keys rotation --older-than 90d --json ``` ## Command Reference **api-keys** — Create and manage API Keys through the Resend API. - `resend-pp-cli api-keys create` — Create a new API key - `resend-pp-cli api-keys delete` — Remove an existing API key - `resend-pp-cli api-keys list` — Retrieve a list of API keys **audiences** — Deprecated: Use Segments instead.

`resend-pp-cli webhooks update` — Update an existing webhook ### Finding the right command When you know what you want to do but not which command does it, ask the CLI directly: ```bash resend-pp-cli which "" ``` `which` resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code `0` means at least one match; exit code `2` means no confident match — fall back to `--help` or use a narrower query. ## Recipes ### Reconstruct what a user has received ```bash resend-pp-cli emails to user@example.com --json --select id,subject,status,sent_at,opened_at --limit 50 ``` Use this for support tickets and GDPR exports — every email sent to one recipient, with delivery state. ### Pre-campaign audience check ```bash resend-pp-cli audiences inventory --json --select name,contact_count,unsubscribed_count,last_broadcast_at ``` Run before scheduling a broadcast — surfaces audiences with high unsubscribe rates or stale engagement. ### Weekly deliverability review ```bash resend-pp-cli deliverability summary --window 7d --agent --select bounce_rate,complaint_rate,suppression_count ``` Trend snapshot for IP/domain reputation; pipe through `jq` to alert on threshold breaches. ### Audit stale API keys ```bash resend-pp-cli api-keys rotation --older-than 90d --json --select name,created_at,last_used_at ``` Find unused keys during quarterly security reviews. ### Search every sent email for a phrase ```bash resend-pp-cli search 'password reset' --json --select id,subject,to,sent_at ``` FTS5-backed; needs `sync --full` first. ## Auth Setup Run `resend-pp-cli auth setup` for the URL and steps to obtain a token (add `--launch` to open the URL). Then store it: ```bash resend-pp-cli auth set-token YOUR_TOKEN_HERE ``` Or set `RESEND_API_KEY` as an environment variable. Run `resend-pp-cli doctor` to verify setup. ## Agent Mode Add `--agent` to any command. Expands to: `--json --compact --no-input --no-color --yes`. - **Pipeable** — JSON on stdout, errors on stderr - **Filterable** — `--select` keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs: ```bash resend-pp-cli api-keys list --agent --select id,name,status ``` - **Previewable** — `--dry-run` shows the request without sending - **Offline-friendly** — sync/search commands can use the local SQLite store when available - **Non-interactive** — never prompts, every input is a flag - **Explicit retries** — use `--idempotent` only when an already-existing create should count as success, and `--ignore-missing` only when a missing delete target should count as success ### Response envelope Commands that read from the local store or the API wrap output in a provenance envelope: ```json { "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."}, "results": } ``` Parse `.results` for data and `.meta.source` to know whether it's live or local. A human-readable `N results (live)` summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout. ## Agent Feedback When you (or the agent) notice something off about this CLI, record it: ``` resend-pp-cli feedback "the --since flag is inclusive but docs say exclusive" resend-pp-cli feedback --stdin < notes.txt resend-pp-cli feedback list --json --limit 10 ``` Entries are stored locally at `~/.resend-pp-cli/feedback.jsonl`. They are never POSTed unless `RESEND_FEEDBACK_ENDPOINT` is set AND either `--send` is passed or `RESEND_FEEDBACK_AUTO_SEND=true`. Default behavior is local-only. Write what *surprised* you, not a bug report. Short, specific, one line: that is the part that compounds. ## Output Delivery Every command accepts `--deliver `. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported: | Sink | Effect | |------|--------| | `stdout` | Default; write to stdout only | | `file:` | Atomically write output to `` (tmp + rename) | | `webhook:` | POST the output body to the URL (`application/json` or `application/x-ndjson` when `--compact`) | Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr. ## Named Profiles A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern. ``` resend-pp-cli profile save briefing --json resend-pp-cli --profile briefing api-keys list resend-pp-cli profile list --json resend-pp-cli profile show briefing resend-pp-cli profile delete briefing --yes ``` Explicit flags always win over profile values; profile values win over defaults. `agent-context` lists all available profiles under `available_profiles` so introspecting agents discover them at runtime. ## Exit Codes | Code | Meaning | |------|---------| | 0 | Success | | 2 | Usage error (wrong arguments) | | 3 | Resource not found | | 4 | Authentication required | | 5 | API error (upstream issue) | | 7 | Rate limited (wait and retry) | | 10 | Config error | ## Argument Parsing Parse `$ARGUMENTS`: 1. **Empty, `help`, or `--help`** → show `resend-pp-cli --help` output 2. **Starts with `install`** → ends with `mcp` → MCP installation; otherwise → see Prerequisites above 3. **Anything else** → Direct Use (execute as CLI command with `--agent`) ## MCP Server Installation Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it: ```bash claude mcp add resend-pp-mcp -- resend-pp-mcp ``` Verify: `claude mcp list` ## Direct Use 1. Check if installed: `which resend-pp-cli` If not found, offer to install (see Prerequisites at the top of this skill). 2. Match the user query to the best command from the Unique Capabilities and Command Reference above. 3. Execute with the `--agent` flag: ```bash resend-pp-cli [subcommand] [args] --agent ``` 4. If ambiguous, drill into subcommand help: `resend-pp-cli --help`.
