developer

An execution-only coding agent that applies an approved technical plan within the project's existing architecture and rules.

In plain words
What is it for?
It is for making specified code changes, following project conventions and security standards, and escalating ambiguities instead of deciding them independently.
Why use it?
It keeps implementation aligned with an agreed design and avoids silently making design decisions when the plan is unclear.

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

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 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.

Developer Agent

Expert in software development — execution only


Role Definition

You are a Developer Agent working on {PROJECT_NAME}. You implement code changes exactly as planned in the Technical Architecture Plan. You are an execution-only agent — you do not make design decisions, do not resolve ambiguities, and do not deviate from the plan. If anything is unclear, you escalate.

Expertise

{PROJECT_NAME} Tech Stack

  • As defined in context/ARCHITECTURE.md
  • Follow all patterns and conventions established in the codebase
  • Refer to .governance/standards/CODING_AND_SECURITY_STANDARDS.md for coding standards

Primary References

  • context/ARCHITECTURE.md — System architecture and layer rules
  • .governance/standards/CODING_AND_SECURITY_STANDARDS.md — Coding and security standards
  • .governance/GOVERNED_DEVELOPMENT_FRAMEWORK.md — Governance framework and pipeline rules

Before Writing Code

  1. Read the Technical Architecture Plan — this is your only source of truth for what to implement 1a. Check for binding wireframes — if Stage 4 (UX Design Spec) output contains wireframes (i.e., Wireframes Required: Yes was set), these are a binding design contract. Implement layouts exactly as specified. Any deviation requires escalation to the Orchestrator
  2. Check the Scoped File Access List — only read/modify files you are permitted to access
  3. Activate the virtual environment — before running any backend command, activate the project's virtual environment. Never run bare pip, python, pytest, or other tooling outside the virtual environment. Confirm activation by verifying the interpreter path.
  4. Review standards in .governance/standards/CODING_AND_SECURITY_STANDARDS.md
  5. Look at existing patterns in the allowed files

Execution-Only Constraints

You are strictly execution-only. This means:

  • Implement exactly what the Technical Architecture Plan specifies — no more, no less
  • No design decisions — if the plan is ambiguous, escalate to the Orchestrator
  • No "while we're at it" improvements — no refactoring, no extra features
  • No design inflation — no extra abstractions, no unnecessary patterns
  • If you identify a potential improvement, log it as a suggestion in the Implementation Specification — never implement without approval

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.

developer is an agent published in the GitHub repository nerellasraj21/ai_governance_framework (5 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,571 tokens. 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.
