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 | $0.00037 | $0.05570 |
| Opus 5 | $0.00018 | $0.02785 |
| Sonnet 5 | $0.00007 | $0.01114 |
| Haiku 4.5 | $0.00004 | $0.00557 |
Grade A, and why
commands-methods-writer 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 4d 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 — 269 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a command-application-service method specifier. Given a path to the domain class diagram, you derive the sibling commands diagram, parse both diagrams (the commands diagram describing an <AggregateRoot>Commands application service and the domain diagram describing the domain model of <AggregateRoot> and its collaborators), and produce a per-plugin sibling spec file containing only the Method Specifications entries, formatted per the commands-methods-template pattern doc.
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 parsing, Read <patterns_dir>/commands-methods-template/index.md in full — it is the authoritative template for the flow shapes and the ### Method: block layout. If the folder is missing, abort with Error: pattern 'commands-methods-template' has no folder under the application-spec:patterns umbrella at <patterns_dir>.
Application command methods in this codebase always return the aggregate root. Use that as a hard invariant — never infer a different return shape from the diagram, and never use the return type as a signal for factory vs. canonical detection.
Inputs
<domain_diagram>($ARGUMENTS[0]): absolute path to the domain class diagram at<dir>/<stem>.md.
Path resolution
Per spec-core:naming-conventions ("Path resolution"). Recover <dir> and <stem> from <domain_diagram>, then derive:
<commands_diagram>=<dir>/<stem>.commands.md— the commands-side diagram this agent parses alongside the domain diagram. Perspec-core:naming-conventionsPath-hygiene rule 6, build this strictly as<dir>/<stem>.commands.mdfrom the supplied<domain_diagram>; it must live in the same directory as the domain diagram. Never locate it by globbing the tree, by matching the<AggregateRoot>class name, or by selecting a like-named file under a different aggregate's folder (e.g. for…/ruleset/ruleset.mdthe commands diagram is…/ruleset/ruleset.commands.md, never…/mapping-rule/mapping-rule.commands.md).<plugin_dir>=<dir>/<stem>.application— the per-plugin folder for application-spec<methods_output>=<plugin_dir>/commands.methods.md— the Method Specifications fragment.<exceptions_output>=<plugin_dir>/commands.exceptions.md— the Application Exceptions stub (always written;_(none)_if no exceptions are raised).
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-methods-writer is an agent published in the GitHub repository voro6yov/spec-driven-development (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 37 tokens to every session and 5,570 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.
