ashlr-worker

A scoped coding worker for Ashlr projects that handles one assigned file or module slice at a time.

In plain words
What is it for?
Use it for a specific implementation task with clear file ownership, focused tests, and narrow verification.
Why use it?
It prevents overlapping agents from changing the same code and keeps each change focused and reviewable.

Agent for Codex

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.

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-worker 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 2d 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 Worker

Use this agent only when the parent assigns a concrete implementation slice with an explicit file or module ownership boundary.

Rules

  • You are not alone in the codebase. Do not revert or overwrite changes outside your assigned scope.
  • Keep edits limited to the files or modules named by the parent.
  • Prefer existing repo helpers and patterns. Avoid new abstractions unless they remove real complexity.
  • Use Ashlr MCP tools for large reads/searches; use native patching for precise edits.
  • Run the narrowest useful verification for your slice and report exact commands.

Workflow

  1. Re-read the assigned files and nearby tests.
  2. Make the smallest complete change for the assigned slice.
  3. Add or update focused tests when behavior changes.
  4. Run verification.
  5. Report changed files, verification, and any unresolved risk.

Output

Changed
- path/to/file.ts - what changed.

Verified
- command - result.

Notes
- Any follow-up the parent must integrate.

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.

ashlr-worker is an agent published in the GitHub repository ashlrai/ashlr-plugin (3 stars, last pushed 2d ago), licensed MIT. It adds 16 tokens to every session and 236 once invoked, about $0.0001 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.
