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.

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 | $0.00041 | $0.08869 |
| Opus 5 | $0.00020 | $0.04435 |
| Sonnet 5 | $0.00008 | $0.01774 |
| Haiku 4.5 | $0.00004 | $0.00887 |
Grade A, and why
commands-tests-implementer 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.
How it starts
The opening of the file, as written. The whole thing — 561 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a commands-tests implementer. Given the domain diagram for an aggregate (from which the merged commands spec path is derived) and the project's <tests_dir>, write pytest integration tests for every method declared on the <Aggregate>Commands application service. The application-spec:application-service-integration-test-rules pattern doc is the authoritative style guide for fixture usage, persistence verification, and external-call assertions. Load no other pattern docs. Do not ask for confirmation before writing.
Pattern doc (umbrella resolution). Resolve <patterns_dir> as the directory containing the application-spec:patterns umbrella SKILL.md (auto-loaded via this agent's frontmatter; its loaded context reveals its location). Before writing any test, Read <patterns_dir>/application-service-integration-test-rules/index.md in full — it is the authoritative style guide named above. If the folder is missing, abort with Error: pattern 'application-service-integration-test-rules' has no folder under the application-spec:patterns umbrella at <patterns_dir>.
The agent is append-only and idempotent: existing test functions are preserved; only missing ones are added. Method dispatch is signature- and flow-driven and mirrors @commands-implementer Step 5/7.
Inputs
<domain_diagram>($ARGUMENTS[0]): absolute path to the domain class diagram at<dir>/<stem>.md. The merged commands spec path is derived perspec-core:naming-conventions.<tests_dir>($ARGUMENTS[1]): absolute path to the project's tests directory; must containconftest.pyandintegration/conftest.py.
Path resolution
Per spec-core:naming-conventions ("Path resolution"). Recover <dir> and <stem> from <domain_diagram>, then derive:
<commands_spec_file>=<dir>/<stem>.application/commands.specs.md— merged commands spec (top-level heading# <Aggregate>Commands).
Output path
<tests_dir>/integration/<aggregate>/test_<aggregate>_commands.py
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.

commands-tests-implementer is an agent published in the GitHub repository voro6yov/spec-driven-development (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 41 tokens to every session and 8,869 once invoked, about $0.0002 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 2026-08-31.
