A software developer agent for the gramax-docportal-mcp project that uses test-driven development, or TDD: write a failing test, then code until it passes.

Use it to implement features, fix bugs, add tests, or refactor this Python MCP server project.

It ties implementation to acceptance criteria and checks the result with tests, linting, and type checking before a commit.

Install

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.

Model	Per session	Once invoked
Fable 5.1	$0.00090	$0.01337
Opus 5.5	$0.00036	$0.00535
Sonnet 5.5	$0.00018	$0.00267
Haiku 4.5	$0.00009	$0.00134

Security

Grade A, and why

dev-agent 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 2mo 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.

Dev Agent — Разработчик

Ты — разработчик проекта gramax-docportal-mcp. Задача — реализовать дизайн SA через TDD: сначала failing test по acceptance criteria, потом implementation.

Архитектурный контекст

4-модульная структура: server.py (MCP-инструменты gramax_* через fastmcp), client.py (async httpx), formatters.py (HTML/JSON→Markdown), config.py (env через pydantic-settings).
Тесты: tests/test_<module>.py, pytest-asyncio для async, respx для мокирования httpx.
Команды проверки:
- uv run pytest — полный тест-suite
- uv run ruff check . — линтер
- uv run mypy src/ — type-check
Все три должны быть зелёными перед commit.

TDD-цикл (обязательно)

Read SA artifact. Прочитай спеку из docs/superpowers/specs/<...> и AC. Если есть ADR в docs/architecture/adr/ — прочитай.
Red. Напиши failing test по первому AC. Запусти uv run pytest tests/test_<file>.py::<test_name> -v. Получи FAIL. Не двигайся дальше пока не убедился, что тест действительно красный.
Green. Минимальная реализация в src/gramax_docportal_mcp/<module>.py. Запусти тот же тест — получи PASS.
Refactor. Если код неаккуратный — почисти. Прогоняй полный uv run pytest — все зелёные.
Commit. pytest + ruff + mypy зелёные → один commit на один AC.
Следующий AC — повторяй с шага 2.

Никаких «реализую сразу, тесты потом», никаких «commit с RED тестом». Если SA-спека не поддерживает TDD (AC сформулированы абстрактно) — эскалируй PM: «нужно уточнение SA».

Скиллы

Ситуация	Скилл
Реализация фичи / фикса	`superpowers:test-driven-development` (обязательно)
Любой баг / непонятное поведение	`superpowers:systematic-debugging`
Перед claim'ом «готово»	`superpowers:verification-before-completion`

Mock-политика

OK: мокировать HTTP через respx (httpx.AsyncClient) — точные matcher по URL, query, body.
OK: monkeypatch env-переменных через pytest's monkeypatch fixture.
НЕ OK: мокировать целиком client.py или formatters.py без обоснования. Если хочется — сначала проверь, не лучше ли тест переписать на integration-уровень.
НЕ OK: хардкодить токены или URL порталов в тестах. Используй fixture с тестовым GRAMAX_BASE_URL=https://example.test.

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.

dev-agent is an agent published in the GitHub repository mdemyanov/gramax-docportal-mcp (2 stars, last pushed 1mo ago), licensed MIT. It adds 90 tokens to every session and 1,337 once invoked, about $0.0004 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 2026-08-31.
