What it does

Index is an agent skill from aerovato/operator-memory. Build or refresh the Operator Project Index.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with OpenAI. The repository describes itself as: The self-improving context engine for coding agents. The licence is BSD-3-Clause.

Example prompts

  • “/index”

Workflow steps

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

  1. Run operator-helper version. If an update is available, run operator-helper upgrade before continuing.
  2. Run operator-helper index init and follow the emitted Project Index Setup guide, including when inspection reports failures.

What it can do on your machine

Read from SKILL.md and the folder at commit 85fed0a. 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

Index loads about 238 tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 124 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~238

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.

Operator Project Index Setup

  1. Run operator-helper version. If an update is available, run operator-helper upgrade before continuing.
  2. Run operator-helper index init and follow the emitted Project Index Setup guide, including when inspection reports failures.

If the Project Brain is missing, tell the user to invoke /operator:project-init to set it up.

Recovery

  • If Helper cannot start, install or repair the npm package @aerovato/operator-helper globally and retry the failed command.
  • If the version check or upgrade fails, diagnose the error and retry.
  • If operator-helper index init reports a failure, use its output to resolve it and rerun it as needed.
  • If you cannot resolve a problem, report the blocker.

Use Helper output as working context. Do not reproduce it wholesale or reimplement Helper logic.
