shared-resend-portfolio

shared-resend-portfolio is a skill for Claude Code, Codex from J-StaR-Films-Studios/VibeCode-Protocol-Suite. It costs 77 tokens per session (1,175 once invoked), scanned A, original, ISC.

A setup pattern for sharing one Resend account and verified sender domain across several branded products. Resend is an email service used to send transactional messages such as receipts or password resets.

In plain words
What is it for?
Use it when adding transactional email to multiple apps, especially solo-developer projects and free-tier portfolios.
Why use it?
It avoids creating a separate email account and domain for every small application while keeping product identities and recipients separated.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

shared-resend-portfolio scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Shared Resend Portfolio

Implement email for multiple products through one Resend account and verified domain. Optimize for a solo developer or small portfolio using the free tier without making every app look like the same product.

Core model

Share infrastructure, not product identity:

One Resend account
└── Existing verified sender domain
    ├── Product A sender identity
    ├── Product B sender identity
    └── Product C sender identity

Each app keeps its own:

  • sender display name
  • destination inbox
  • Reply-To routing
  • subject conventions
  • branded HTML and plain-text templates
  • deployment environment variables
  • delivery logs and failure behavior

All apps share the account-level free-tier quota and verified-domain reputation.

Portfolio discovery

Before implementation:

  1. Inspect the target app and any sibling app with a working Resend setup.
  2. Identify the canonical Resend account and already verified domain.
  3. Confirm the product display name, shared sender mailbox, internal recipient, support Reply-To inbox, and expected email types.
  4. Confirm whether the target deployment already has a Resend API key.
  5. Do not ask the user to create another account, verify another domain, or buy a plan unless the existing account cannot meet a stated requirement.

Account and key strategy

Reuse the same Resend account and verified domain. Prefer a separate API key per deployed app when the account permits it; this limits the impact of a leaked or rotated key while remaining on one account and quota. Reuse the same key only when separate keys are unavailable or the user explicitly prefers that trade-off.

Never copy secrets from another repository into source control. Add the selected key directly to each deployment’s secret environment.

Per-product configuration

Use server-only variables and product-specific names where practical. Resolve their values from the user's existing Resend account, verified sender configuration, and intended product inbox—never copy example identities into an implementation.
