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 | $0.01789 | $0.01789 |
| Opus 5.5 | $0.00716 | $0.00716 |
| Sonnet 5.5 | $0.00358 | $0.00358 |
| Haiku 4.5 | $0.00179 | $0.00179 |
Grade A, and why
sdcorejs-agent copilot-instructions.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 1mo 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 - GitHub Copilot Instructions
Use this repo as a Runtime-localized SDLC skill pack for AI-agent, Angular, NestJS, Next.js, product-track, design-track, test-track, and generic harness work.
Dispatch
- Glob
skills/**/*.mdand read frontmatter only. - Match the user request against each skill
description. - Read the selected skill body before acting.
- If no skill matches, invoke
sdcorejs-using-skills.
Resolve track/profile/repository/evidence semantics from the versioned
_refs/shared/system-registry.json. Keep track, stack profile, capability
profile, repository role, artifact owner, and execution host distinct. Current
working directory is not artifact-owner evidence.
If several skills match, apply this priority: explicit skill name, approved-plan execution, product docs/traceability, design handoff, test-only work, dedicated utility intent, confirmed track implementation, then brainstorming for ambiguous scope.
Workflow
Request
-> sdcorejs-brainstorming
-> sdcorejs-spec (approval gate + approved spec snapshot)
-> sdcorejs-plan (approval gate + approved plan snapshot)
-> sdcorejs-execute-plan
ask execution mode only when both modes are feasible
dispatch ai-agent | Core UI angular | nestjs | nextjs | product | design | test | generic harness
-> finish gate and tail chain
tests -> optional sdcorejs-simplify -> affected focused tests
-> review/repair -> documentation/task/memory -> ship gates
Track executors:
- Angular:
sdcorejs-angularonly for Core UI portals/new SDCoreJS portals/approved Core UI migration; plain Angular uses the generic harness - NestJS:
sdcorejs-nestjs - Next.js:
sdcorejs-nextjs - AI-agent:
sdcorejs-ai-agentonly for an approved plan with one engine and one independent capability profile - Product:
sdcorejs-product - Design:
sdcorejs-design - Test:
sdcorejs-test - Generic:
sdcorejs-execute-planharness fallback
Under-specified AI-agent requests return to brainstorming. Test, review, and debug intent keep their dedicated owners. The AI-agent track authors governed application contracts/integration and offline evidence; it does not bundle a provider runtime or imply live verification.
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.
