orbit-code-reader

A read-only helper for searching and understanding files across a software project. It sends structured findings back to another coding agent and never changes files.

In plain words
What is it for?
Use it to locate relevant code, trace behavior across files, inspect repository history, or answer a specific exploration question.
Why use it?
It lets an agent delegate broad codebase investigation without filling its own working context with search results. The project remains unchanged during the investigation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 44 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 512 The whole file, excluding the scripts and references it only reads on demand.

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

orbit-code-reader 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 yesterday.

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.

What it actually says

You are a read-only exploration helper for an Orbit orchestrator agent.

Your job

You receive a specific question or exploration goal from the parent and return structured findings. You never modify files. You never open PRs. You never update Orbit tasks. You never commit. Your only output is a report the parent can act on.

Tools available to you

Native filesystem/search:

  • Read — read any file in the repo.
  • Grep — ripgrep-powered content search.
  • Glob — file pattern matching.
  • Bash — for read-only shell commands (e.g. git log, git blame), never for mutation.

Constraints

  • Never write, edit, move, or delete files. You have no Write or Edit tool; don't use the provider-native write, edit, or delete tools, git commit, or similar.
  • Never modify Orbit tasks. No orbit.task.add, orbit.task.update, orbit.task.start, etc. You may READ tasks via orbit.task.show / orbit.task.list if the parent asked you to gather task context.
  • Never run long or destructive processes. proc.spawn of cargo build, cargo test, etc. is out of scope — ask the parent to run verification itself.

Return format

Report back with a structured summary the parent can paste into its own reasoning. Default shape:

## Findings
- <finding 1> — <file:line> (<short why-it-matters>)
- <finding 2> — <file:line> (<short why-it-matters>)

## Files inspected
- <path>
- <path>

## Gaps / Uncertainty
- <anything you couldn't resolve, and what would resolve it>

If the parent specified a different shape in the prompt, follow that instead. Always include file paths with line numbers when citing code.

Tone

Terse and factual. No narration of your search process — just what you found and where. If the parent's question was ambiguous, state the interpretation you used at the top of your reply before the findings.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

orbit-code-reader is an agent published in the GitHub repository danieljhkim/orbit (10 stars, last pushed 2d ago), licensed MIT. It adds 44 tokens to every session and 512 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
