sdcorejs-ai-agent

sdcorejs-ai-agent is a skill for Claude Code from sdcorejs/sdcorejs-agent. It costs 81 tokens per session (2,263 once invoked), scanned A, original, MIT.

A workflow for implementing approved AI-agent designs with declared engine and capability profiles. It covers agent contracts, tools, safeguards, approvals, state, tracing, evaluation, and tests without making live provider calls.

In plain words
What is it for?
Use it after an AI-agent plan and specification have been formally approved. It helps create and verify agent integrations, tool boundaries, approval policies, stored state, evaluations, and tests.
Why use it?
It prevents an agent implementation from proceeding with missing or ambiguous architecture, permissions, or verification details. The approval and identity checks keep execution tied to the approved design.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is common_security_floor: ../../_refs/ai-agent/profiles/common.md.

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-ai-agent 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 16d 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 AI Agent

Execute an approved AI-agent plan as an authoring track. This skill produces application contracts, integration code, deterministic tests, and verification evidence. It does not install a provider runtime into this skill pack and it does not perform live provider calls.

Entry Gate

Require all of the following before writing:

  • an immutable approved plan with track: ai-agent;
  • its immutable approved spec and shared approval_hash;
  • a valid plan approval_hash whose verified parent graph includes that spec;
  • an agent_architecture block that names one engine_profile, one capability_profile, target paths, trust boundaries, tool boundaries, persistence policy, approval policy, eval policy, and verification commands;
  • explicit user selection of sequential or parallel execution through sdcorejs-execute-plan.

If any item is absent, ambiguous, stale, or hash-invalid, stop and return to the owning workflow gate. Do not infer a profile from prose after plan approval. Create and verify approved spec/plan identity only through ../../_refs/shared/approved-artifact.mjs; do not use a track-local hash scheme. When a legacy portable handoff names these values approved_spec_hash and approved_plan_hash, each value must equal the corresponding shared approval_hash; the aliases do not authorize an independent hash contract.

Shared Protocols

Read ../../_refs/shared/runtime-protocols.md, ../../_refs/shared/system-registry.json, and ../../_refs/ai-agent/manifest.json. Apply ../../_refs/shared/artifact-lifecycle.md when .sdcorejs/** is written. Use ../../_refs/shared/repository-contract.mjs for repository ownership and ../../_refs/ai-agent/execution-identity.mjs for profile resolution, approved graph verification, runtime approval fingerprints, downstream artifact identity, and offline/live evidence classification.

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.
