What it does

Novu Manage Subscribers is an agent skill from novuhq/novu. Create, update, search, and delete subscribers in Novu. Manage topics for group-based notification targeting. Set subscriber credentials for push and chat channels. Use when managing notification recipients, creating subscriber records, organizing subscribers into topics, or configuring channel-specific credentials.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/credentials-examples.md`, `references/subscriber-crud-examples.md` and `references/topics-examples.md`).

The repository describes itself as: The open-source communication infrastructure for agents and products.

When your agent uses it

  • Managing notification recipients
  • Creating subscriber records
  • Organizing subscribers into topics
  • Configuring channel-specific credentials

Example prompts

  • “/novu-manage-subscribers”

Requirements

  • A credential in NOVU_SECRET_KEY

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. subscriberId is YOUR user ID — it bridges your system to Novu. Use a stable, unique identifier from your database.
  2. Subscribers are auto-created on trigger — if you pass a full subscriber object in to when triggering, Novu creates the subscriber if it…
  3. Subscriber data is per-environment — dev, staging, and production have separate subscriber records.
  4. Topics must exist before triggering — create the topic and add subscribers before sending to it.
  5. Deleting a subscriber doesn't delete their notifications — existing notifications remain in the system.
  6. Adding non existent subscriber to topic - if non existent subscriber is added to topic, it is not autocreated in that environment and…

What it can do on your machine

Read from SKILL.md and the folder at commit c4d3eda. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NOVU_SECRET_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Novu Manage Subscribers loads about 1.3k tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 85 tokens; SKILL.md has 263 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.2k

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.

Safety

Auto-check passed

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 263 words (~1,334 tokens).

“Subscribers are the recipients of your notifications. Each subscriber has a unique subscriberId — typically your application's user ID.”
