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 | $0.03606 | $0.03606 |
| Opus 5.5 | $0.01442 | $0.01442 |
| Sonnet 5.5 | $0.00721 | $0.00721 |
| Haiku 4.5 | $0.00361 | $0.00361 |
Grade A, and why
sdcorejs-agent CLAUDE.md 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 25d 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 SDLC Agent - Claude Code Instructions
Claude Code entry point for the SDCoreJS skill pack. The same skill model is mirrored to Codex, Cursor, and Copilot through their entry files.
This repo provides Runtime-localized engineering skills for developers and technical teams working across the software delivery lifecycle:
- Angular portals with
@sdcorejs/angular - NestJS + Postgres backends
- Next.js public sites
- Governed AI-agent application contracts and implementations
- A product track for PO-facing docs plus feature ledgers and traceability
- A design track for FE handoff artifacts from product user stories
- A first-class test track
- A generic execution harness for unsupported stacks or non-track plans
Skill Source Language
Author this skill pack in English only. skills/**, _refs/**, prompts,
templates, examples, generated mirrors, and validation fixtures must not embed
Vietnamese prose or Vietnamese-only sample UI text. Runtime localization belongs
to the consuming project/session: instructions may say to translate or localize
output at runtime, but the reusable skill source itself stays English and
locale-neutral. Use placeholders such as <localized label> instead of concrete
Vietnamese labels.
Localization test prompts may use non-English input when they are explicitly fixtures for dispatch/runtime-localization behavior. Expected source text, generated mirrors, reusable examples, and expected generated skill prose must remain English-only and locale-neutral.
Dispatch
At session start, glob skills/**/*.md, excluding _refs/**, and read frontmatter only. Match user requests against each skill description. Read the selected skill body before acting.
Resolve tracks, stack profiles, repository roles, artifact ownership, review/
repair/ship support, and evidence classes from the versioned
_refs/shared/system-registry.json. A capability profile refines an approved
track; it is not a track. Keep the semantic artifact owner separate from the
execution host, and never use the current working directory to infer ownership.
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.
