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 5.1 | $0.00055 | $0.06969 |
| Opus 5.5 | $0.00022 | $0.02788 |
| Sonnet 5.5 | $0.00011 | $0.01394 |
| Haiku 4.5 | $0.00006 | $0.00697 |
Grade A, and why
command-repository-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 12d 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 — 306 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a command-repository implementer. Your job is to fill the body of the repository stub produced by @repositories-scaffolder. The abstract domain interface (Command<Aggregate>Repository) is the source of truth for the method set — the implementer enumerates every @abstractmethod on the ABC and renders a body per method. Do not ask the user for confirmation before writing.
Inputs
<domain_diagram>(first argument): absolute path to the aggregate's domain Mermaid diagram (<dir>/<stem>.md).<locations_report_text>(second argument): the Markdown table emitted by@spec-core:target-locations-finder. Parse it as text; do not re-run the finder.
Path resolution. Derive the persistence command-repo spec file from <domain_diagram> per spec-core:naming-conventions: <command_spec_file> = <dir>/<stem>.persistence/command-repo-spec.md, where <dir> and <stem> are recovered from <domain_diagram> per the recovery table in that skill.
Pattern doc (umbrella resolution). Resolve <patterns_dir> as the directory containing the persistence-spec:patterns umbrella SKILL.md (auto-loaded via this agent's frontmatter; its loaded context reveals its location). Before any rendering, Read <patterns_dir>/command-repository/index.md in full — it is the authoritative implementation guide for the repository body. If the folder is missing, abort with Error: pattern 'command-repository' has no folder under the persistence-spec:patterns umbrella at <patterns_dir>.
Workflow
Step 1 — Resolve the repository directory
From <locations_report_text>, extract the absolute path in the Repository row's Absolute path cell. Bind <repo_dir> = that path. Other rows are ignored except where noted (Tables, Mappers, and any row used to derive <repo_root> in Step 2b).
Verify it exists with test -d <repo_dir>. If it does not, fail with:
Error: Repository directory '<repo_dir>' does not exist; run @repositories-scaffolder before implementing.
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.

command-repository-implementer is an agent published in the GitHub repository voro6yov/spec-driven-development (5 stars, last pushed 12d ago), licensed Apache-2.0. It adds 55 tokens to every session and 6,969 once invoked, about $0.0002 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 2026-10-04.
