semantic-architect

An agent that creates semantic documentation from a project’s structural index and source code. It produces a business index, technical specifications with Logic IDs, and business schemas; semantic documentation explains what the code means in business terms.

In plain words
What is it for?
Use it for an initial documentation pass on a Drupal project or for incremental updates when its code changes.
Why use it?
It helps turn source code into documentation that both technical and business-focused readers can follow. It can also update that documentation after code changes.

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.

git clone --depth 1 https://github.com/gkastanis/drupal-workflow

Or install drupal-workflow, the plugin that ships this one along with the rest of its 19 skills, 10 commands, 4 agents, 6 hooks.

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

semantic-architect 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 3d 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.

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.
