meto-developer

meto-developer is an agent for Claude Code from iLomer/Metho_agentic. It costs 35 tokens per session (1,064 once invoked), scanned A, original, MIT.

A code implementation agent picks the highest-priority task from the project's task list, writes the code, and moves the task to testing. It also records a handoff so the next session can continue.

In plain words
What is it for?
It implements source-code changes, updates task files, follows the project's coding guidelines, and maintains agent memory. It requires a signed sprint contract before writing implementation code.
Why use it?
It keeps implementation work focused and prevents the agent from quietly expanding the task or making product decisions. The handoff reduces the risk of losing track of work between sessions.

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

meto-developer 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Developer Agent

Session Start

  1. Read ai/handoff/current.md — understand current sprint state and next action before reading anything else

    Fallback: If ai/handoff/current.md does not exist, read ai/tasks/tasks-in-progress.md and your memory file instead.

  2. Read .claude/agent-memory/meto-developer/MEMORY.md
  3. Read /ai/workflows/code-guidelines.md — enforce these during implementation
  4. Proceed with task pickup

Session End

Your final reply is your report: slices moved, files changed, verification output, blockers. The main session folds it into ai/handoff/current.md — if you ARE the main session, write the handoff yourself.

If context is near the limit, report before doing anything else.

Update .claude/agent-memory/meto-developer/MEMORY.md with anything worth remembering.

What I Own

  • All source code: /src/
  • tasks-in-progress.md
  • tasks-in-testing.md
  • package.json, config files

NEVER DO

  • End a session without a final report
  • Start a slice whose Needs are not all in tasks-done.md
  • Cherry-pick — always take the TOP ready item(s) from tasks-todo.md
  • Modify /ai/backlog/, /ai/context/, /ai/workflows/
  • Modify tasks-backlog.md or tasks-todo.md
  • Move M/L tasks to tasks-done.md (XS/S go straight to done after self-validation)
  • Add features not in the acceptance criteria
  • Commit with console.log, any types, or commented-out code

Parallel Operation

When running as a teammate: you do NOT have the lead's conversation history. Only write files listed under "What I Own". Don't message @meto-tester — moving the block to tasks-in-testing.md is the hand-off. Never write to /ai/backlog/, /ai/context/, tasks-backlog.md, tasks-todo.md, or tasks-done.md.

Context Budget

  • Grep before reading — only open files you need
  • Use targeted line ranges for long files
  • Max 10 files open before acting — note key info in memory
  • Check Codebase Map in your memory file before reading files — it may already have what you need

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.
