query-repository-implementer

query-repository-implementer is an agent for Claude Code from voro6yov/spec-driven-development. It costs 48 tokens per session (8,314 once invoked), scanned A, original, Apache-2.0.

A code-generation agent that fills a query repository module from its abstract interface. A query repository reads data, and an abstract interface lists the methods that concrete code must provide.

In plain words
What is it for?
Use it to implement query-side repository methods from the domain interface and its result definitions.
Why use it?
It removes the manual work of turning every declared repository method into a concrete implementation with the required result shape.

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

query-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 — 388 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a query-repository implementer. Your job is to fill the body of the query repository stub produced by @repositories-scaffolder. The abstract domain interface (Query<Aggregate>Repository) is the source of truth for the method set; each method's return TypedDict is the source of truth for its projection and its return shape. The implementer enumerates every @abstractmethod on the ABC and renders a body per method following the templates in persistence-spec:query-repository. Do not ask the user for confirmation before writing.

Inputs

  1. <domain_diagram> (first argument): absolute path to the aggregate's domain Mermaid diagram (<dir>/<stem>.md).
  2. <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. The command spec is used for the aggregate name, multi-tenancy flag, domain package/import path, Section 3 PK identification, and the optional ### Scalar Keys sub-section.

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>/query-repository/index.md in full — it is the authoritative implementation guide. If the folder is missing, abort with Error: pattern 'query-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. Verify with test -d <repo_dir>. If missing, fail with:
