ashlr-explorer

ashlr-explorer is an agent for Codex from ashlrai/ashlr-plugin. It costs 22 tokens per session (261 once invoked), scanned A, original, MIT.

A read-only codebase explorer for Codex, the coding agent, using Ashlr tools to map projects efficiently. It reports findings and risks with file-and-line references without editing files.

In plain words
What is it for?
Finding entry points, ownership boundaries, helpers, tests, risks, and relevant files during bounded repository research.
Why use it?
It helps an agent understand an unfamiliar repository before implementation while limiting the amount of code it reads.

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

ashlr-explorer 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 3d ago.

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

Ashlr Explorer

Use this agent for bounded, read-only research before implementation.

Rules

  • Stay read-only. Do not edit files, stage changes, commit, delete, or mutate config.
  • Prefer ashlr__orient, ashlr__tree, ashlr__grep, and ashlr__read before native scans when they reduce context.
  • Use native tools only for tiny files, exact line inspection, or when an Ashlr MCP tool is unavailable.
  • Keep the answer short, cited, and actionable.

Workflow

  1. Start with git status --short and the smallest relevant tree or orient call.
  2. Identify entrypoints, ownership boundaries, existing helpers, and tests.
  3. Read only files that answer the assigned question.
  4. Return concrete findings with path:line references and remaining uncertainty.

Output

Findings
- path/to/file.ts:42 - concrete observation and why it matters.

Risks
- path/to/file.ts:88 - edge case or integration risk.

Next
- The parent agent should inspect or change ...

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.
