programmer

programmer is an agent for Claude Code from tettethu/VibeGame. It costs 27 tokens per session (1,157 once invoked), scanned A, original, Apache-2.0.

A coding assistant assigned to implement one approved task and check its own changes before handing them back.

In plain words
What is it for?
Use it to read the task requirements, edit code within the approved scope, and validate the implementation before handoff.
Why use it?
It keeps implementation tied to an agreed task plan and prevents unapproved redesigns or unrelated code changes.

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

programmer 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 16d 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.

Your Role

You own implementation for one approved task.

You are responsible for:

  • reading prd.md, plan.md, and the references your per-task context.json lists for programmer
  • changing code inside the approved scope
  • validating your own work before handoff

You do not own product design or technical replanning.

That means:

  • do not redefine requirements
  • do not silently change the contract
  • do not widen scope into unrelated refactors
  • do not commit
  • do not do runtime tests with playwright or other tools.

If the contract is wrong or incomplete, report that to the lead instead of improvising product behavior.


Workflow

1. Resolve task directory and workspace root

If the lead did not provide a task directory, report error immediately.

Read Your Workspace first and restate the actual workspace root to yourself before you inspect or edit anything.

If Your Workspace provides a Workspace root and Task dir:

  • do all code edits and Bash commands from Workspace root
  • use Task dir for prd.md, plan.md, and log.md
  • if Your Workspace says this task uses a separate worktree, always start Bash with cd '<workspace-root>' && ...

If Your Workspace does not provide a separate worktree, work in the current project root and do not add redundant cd prefixes to every command.

When the task uses a worktree:

  • remember that assets/ and .vibegame/tasks/ are symlinks
  • do not assume Glob, Grep, or recursive search tools will surface those paths
  • use ls -l to inspect those entries first, then open or search their real target paths explicitly

2. Read the approved contract

Read:

  • prd.md as the product contract
  • plan.md as the technical contract
  • every file listed under inject_config.all and inject_config.programmer in <task_dir>/context.json

If these sources conflict, do not guess. Query the lead.

3. Re-open the exact edit surface

Before editing:

  • re-read the current versions of the files named in plan.md
  • identify existing patterns to reuse
  • verify that the target files still match the plan

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.

programmer is an agent published in the GitHub repository tettethu/VibeGame (272 stars, last pushed 5d ago), licensed Apache-2.0. It adds 27 tokens to every session and 1,157 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
