sdcorejs-nestjs

sdcorejs-nestjs is a skill for Claude Code, Codex from sdcorejs/sdcorejs-agent. It costs 89 tokens per session (975 once invoked), scanned A, original, MIT.

A guided code executor for NestJS, a framework for building Node.js back-end applications. It handles approved backend changes after requirements have been confirmed.

In plain words
What is it for?
Implementing NestJS backend features, CRUD operations, workflows, bulk actions, exports, and work that reuses the listed utility package.
Why use it?
It provides a defined process for making project, module, entity, endpoint, workflow, and data-operation changes without deciding requirements on its own.

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

sdcorejs-nestjs 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.

SDCoreJS NestJS Executor

Shared protocols

Before execution:

  1. Read _refs/shared/runtime-protocols.md, then apply _refs/shared/tasklist.md.
  2. Read and apply _refs/shared/project-context.md as a read-only, relevance-first context assembler.
  3. Read _refs/shared/artifact-lifecycle.md and merge producer artifact_context through the finishing tail.
  4. Read and apply _refs/shared/user-choice-prompt.md before any user-facing choice, approval, or finish gate.
  5. Use valid summary sections when available. Missing or stale summary never blocks generation; continue with targeted reads or a scoped code map.
  6. Read _refs/nestjs/pack-manifest.json, _refs/nestjs/profile-contract.json, and _refs/nestjs/core-catalog.md.
  7. Before authoring a helper, read _refs/shared/sdcorejs-utils.md.

Resolve the generation contract once

Resolve profile exactly once from the approved plan or fresh project summary. Use simple only when no profile is declared. Validate the resolved profile against profile-contract.json, store it in the run context, and pass the same resolved profile unchanged to every dispatched pack. A pack must not infer, override, or downgrade the profile.

Fail before writing when:

  • the manifest/profile schema is invalid;
  • required pack inputs are missing;
  • an output would escape the target root or overwrite undeclared files;
  • an enterprise operation lacks trusted tenant context;
  • authentication or permission metadata cannot be generated.

Dispatch graph

Read packs on demand in manifest dependency order:

  1. _refs/nestjs/write-code/init-project.md for a new backend.
  2. _refs/nestjs/write-code/init-admin.md for the required authn/authz authority.
  3. _refs/nestjs/write-code/init-module.md for each bounded context.
  4. _refs/nestjs/write-code/init-entity.md for explicit entity routes and stacks.
  5. _refs/nestjs/write-code/actions.md for workflow, import, export, or custom actions.

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.
