recoup-platform-email-helperSend an email via the Recoup API the reliable way — a Node helper that serializes the body correctly and fails loudly instead of sending an empty email.
Recoup Platform Email Helper is an agent skill from aiskillstore/marketplace. Send an email via the Recoup API the reliable way — a Node helper that serializes the body correctly and fails loudly instead of sending an empty email. Use whenever a task needs to email a report/summary/notification to the account owner or a recipient. ALWAYS use this script to send email; never hand-build curl … -d "{…}" with inline jq/shell interpolation (that silently produces empty "Message from Recoup" footer-only emails). Pairs with recoup-platform-api-access (which it sends through).
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `skill-report.json`).
The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
2 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 44923f3. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
nodecurljqFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
RECOUP_API_KEYRECOUP_ACCESS_TOKENFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Recoup Platform Email Helper loads about 712 tokens when it runs. Until then it costs about 133 tokens; SKILL.md has 274 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
Without a licence we can't republish the file, so here is its outline and opening line. It has 274 words (~712 tokens).
“Send email by running the bundled Node script — do not assemble JSON in the shell.”

Recoup Platform Email Helper fits situations like: A task needs to email a report/summary/notification to the account owner.
Run `npx skills add aiskillstore/marketplace --skill recoup-platform-email-helper -a claude-code`. Or copy the skill folder (skills/recoupable/recoup-platform-email-helper in aiskillstore/marketplace) into .claude/skills/recoup-platform-email-helper in your project. Claude Code loads it when a task matches its description.
Run `npx skills add aiskillstore/marketplace --skill recoup-platform-email-helper -a codex`. Or copy the skill folder (skills/recoupable/recoup-platform-email-helper in aiskillstore/marketplace) into .agents/skills/recoup-platform-email-helper in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill recoup-platform-email-helper -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/recoup-platform-email-helper, .gemini/skills/recoup-platform-email-helper, .github/skills/recoup-platform-email-helper and .opencode/skills/recoup-platform-email-helper in your project.
Going by SKILL.md and its folder, Recoup Platform Email Helper needs JavaScript for the scripts in its folder, the command-line tools its instructions call (node, curl and jq) and credentials named RECOUP_API_KEY and RECOUP_ACCESS_TOKEN. Our summary lists: Node.js; A credential in RECOUP_API_KEY; A credential in RECOUP_ACCESS_TOKEN.
SKILL.md contains no URLs. Its commands use curl, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
No licence was found for Recoup Platform Email Helper or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 712 tokens (SKILL.md is roughly 2.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
