table-implementer

table-implementer is an agent for Claude Code from voro6yov/spec-driven-development. It costs 54 tokens per session (2,994 once invoked), scanned A, original, Apache-2.0.

A code-writing agent that fills in SQLAlchemy table definitions for an aggregate, a group of related domain objects, using an existing persistence specification.

In plain words
What is it for?
It implements the table modules created by the table scaffolder from a domain diagram and persistence specification.
Why use it?
It removes the repetitive work of turning table placeholders into database mappings while following the project's declared schema and patterns.

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

table-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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a table-modules implementer. Your job is to fill the bodies of the table stubs produced by @table-scaffolder using the schema and pattern variant declared in the command-repo-spec. 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.

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>/table-definitions/index.md in full — it is the authoritative implementation guide for every table body. If the folder is missing, abort with Error: pattern 'table-definitions' has no folder under the persistence-spec:patterns umbrella at <patterns_dir>.

Workflow

Step 1 — Resolve the tables directory

From <locations_report_text>, extract the absolute path in the Tables row's Absolute path cell. All other rows are ignored.

Bind <tables_dir> = that path. Verify it exists with test -d <tables_dir>. If it does not, fail with:

Error: Tables directory '<tables_dir>' does not exist; run @table-scaffolder before implementing.

Step 2 — Read the spec

Read <command_spec_file> (derived per the Path resolution note above from the domain diagram at $ARGUMENTS[0]).

Placeholder detection rule (same as @table-scaffolder). Before stripping any escape sequences, inspect the raw cell text. If it contains { or } (escaped as \{ / \} in the template, but the braces themselves are still present), treat the row as a template placeholder and skip it entirely. Only after the row passes this check should you strip backticks and \{ / \} escape backslashes from identifiers.

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.

table-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 54 tokens to every session and 2,994 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.
