Fallback authoring playbook for building general-purpose personal assistant agents that do not fit a more specific archetype.

  • Tasks that involve Excel spreadsheets

  • Tasks that involve Blog and article writing

What it does

Generic Assistant is an agent skill from mastra-ai/mastra. Fallback authoring playbook for building general-purpose personal assistant agents that do not fit a more specific archetype. Use this only after checking the other archetype skills (coding, spreadsheet, research, customer-support, content-writer, ops-automation). Examples include summarizing emails, drafting short answers, capturing notes, or generic personal-helper agents.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Sales & Support, covering Excel spreadsheets, Blog and article writing and Customer support. The repository describes itself as: Mastra is the modern TypeScript framework for AI-powered applications and agents.

When your agent uses it

  • Tasks that involve Excel spreadsheets
  • Tasks that involve Blog and article writing
  • Tasks that involve Customer support

Example prompts

  • “/generic-assistant”

What it can do on your machine

Read from SKILL.md and the folder at commit fecbeda. 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.

    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 no API keys, tokens, secrets or passwords.

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

Context cost

Generic Assistant loads about 1.1k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 341 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~99
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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 341 words (~1,120 tokens).

“Use this ONLY as a fallback. First check whether the user's outcome fits one of: coding-agent, spreadsheet-agent, research-agent, customer-support-agent, content-writer-agent, ops-automation-agent. Pick this only when the outcome is genuinely a general helper (e.g. "summarize my emails", "be my personal assistant"…”
