template-code-development

A development workflow for adding infrastructure or project code to a research project template. It covers implementation, tests, documentation, and verification.

In plain words
What is it for?
Use it to add algorithms, utilities, analysis methods, optimizers, validators, or modules with tests and checks.
Why use it?
It helps keep new code in the correct project layer and aligned with the template's type, logging, testing, and coverage rules.

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

template-code-development 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 yesterday.

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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code development

Natural invoke

  • "Implement gradient descent in template_code_project src/"
  • "Add a generic CSV validator in infrastructure/"
  • "New analysis method with tests and logging"

Inputs to confirm

  • Task — what to implement.
  • Layerinfrastructure (generic, 60% cov) vs project (domain, 90% cov).
  • Project — if layer is project, from docs/_generated/active_projects.md.

Workflow

  1. Place logic correctly — computation in infrastructure/ or projects/<n>/src/; scripts only orchestrate I/O and plotting.

  2. Implement — type hints on public APIs; get_logger(__name__); custom exceptions extending TemplateError; Google docstrings.

  3. Tests — real data, temp files, subprocess, or pytest-httpserver; no mocks (docs/rules/testing_standards.md).

  4. Docs — update module/folder AGENTS.md + README.md when adding public surface.

  5. Verify — ruff/mypy on touched paths; pytest with coverage gate.

Deliverables

  • Module(s) with tests meeting coverage floor
  • List of files touched and verification command output

Verification commands

uv run python -m infrastructure.project.public_scope lint-paths | xargs uv run ruff check
uv run python -m infrastructure.project.public_scope source-paths | xargs uv run mypy
uv run pytest projects/<project>/tests/ --cov=projects/<project>/src --cov-fail-under=90 -q
# or infra:
uv run pytest tests/infra_tests/ --cov=infrastructure --cov-fail-under=60 -q

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

template-code-development is a skill published in the GitHub repository docxology/template (19 stars, last pushed yesterday), licensed Apache-2.0. It adds 88 tokens to every session and 684 once invoked, about $0.0004 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 2026-08-30.
