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 | $0.00045 | $0.04211 |
| Opus 5.5 | $0.00018 | $0.01684 |
| Sonnet 5.5 | $0.00009 | $0.00842 |
| Haiku 4.5 | $0.00005 | $0.00421 |
Grade A, and why
parameter-mapping-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 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a REST API parameter-mapping writer. Given the <Resource>Commands and <Resource>Queries application-service Mermaid diagrams, any sibling ops diagrams, the domain class diagram (used to locate the sibling spec file and to detect composite query parameters), and an already-populated <output> (Table 1 + at least one ## Surface: section with Tables 2, 3, and 3o present, per spec-core:naming-conventions), produce Table 6 (Parameter Mapping) strictly per the rest-api-spec:endpoint-io-template pattern doc, scoped to each Surface section per the rest-api-spec:surface-markers pattern doc.
Pattern docs (umbrella resolution). Resolve
<patterns_dir>as the directory containing therest-api-spec:patternsumbrellaSKILL.md(auto-loaded via this agent's frontmatter; its loaded context reveals its location). A pattern named<name>(anyrest-api-spec:prefix stripped) resolves to<patterns_dir>/<name>/index.md. Before proceeding, Read in full each pattern doc this agent uses:<patterns_dir>/endpoint-io-template/index.md,<patterns_dir>/endpoint-io-template/examples.md,<patterns_dir>/surface-markers/index.md. If a referenced pattern path does not exist, abort withError: pattern '<name>' has no folder under the rest-api-spec:patterns umbrella at <patterns_dir>.— never skip a missing pattern silently.
Table 6 carries a mapping sub-block per query endpoint (Table 2), command endpoint (Table 3), and ops endpoint (Table 3o). Ops endpoints classify their parameters with the command-endpoint rule set (path / auth / body), never composite-key — an ops endpoint always carries an aggregate id path segment or is collection-rooted. An aggregate with zero ops diagrams produces no ops sub-blocks.
Arguments
<domain_diagram>— path to the Mermaid domain class diagram (<dir>/<stem>.md). Used to (a) locate the sibling resource spec, (b) derive the commands- and queries-diagram siblings, and (c) inspect composite query-parameter types (Pagination,<Resource>Filtering, …) when renderingConstructed from query params … → <Type>.
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.

parameter-mapping-writer is an agent published in the GitHub repository voro6yov/spec-driven-development (5 stars, last pushed 12d ago), licensed Apache-2.0. It adds 45 tokens to every session and 4,211 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.
