stack

stack is a skill for Claude Code from Tradebaas/Groundwork. It costs 0 tokens per session (1,853 once invoked), scanned A, original, MIT.

Guidance for choosing the technology platform and making a project fit that platform's current practices. The platform may be a programming stack or a hosted service such as Salesforce or ServiceNow.

In plain words
What is it for?
Use it when selecting or changing a language, framework, hosting service, or low-code platform, and when comparing options for fit, cost, hiring, handover, or compliance.
Why use it?
It makes the technology choice explicit instead of assuming one by habit. It also requires checking current platform facts and recording the trade-offs behind the recommendation.

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

stack 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 6d 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.

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

stack: choose deliberately, then be born current

"Stack" here means whatever the product is built on: a language and framework on self-chosen infrastructure, or a hosted platform where the product is largely configured (Power Platform, ServiceNow, Salesforce, Google's builders, or any successor). This skill carries a method, not a platform table; every platform fact is looked up live from the vendor's current official documentation, so platforms and practices that appear after this skill was written are in scope automatically.

1. Decide the stack: options on merit

Derive candidates from BRIEF.md (target, users, constraints, integrations, team). Hosted platforms are candidates on equal footing when the brief points there (existing tenant, licensing, citizen-developer handover). Present 2-3 genuinely different options with honest trade-offs (fit, ecosystem maturity, hiring/handover, cost, compliance implications, e.g. EU data residency of managed services). Recommend one; the owner confirms. Record as a decision record with the options and the reason.

Verify before recommending. Versions, support status, pricing, EU-residency: check current authoritative sources (official docs, release pages). Model memory is a rumor with a cutoff.

2. Generate docs/standards/<stack>.md

Existing project: read what the code already does before writing a rule. The linter and formatter it configures, the test runner and where the tests live, the module layout, the naming in use, the stages its CI runs: these are the standards the project has, and the file records them first. A convention the code follows stays unless it fails the floor; a new one arrives with its reason and its migration path, never by a rewrite of what works.

Start from docs/standards/TEMPLATE-STACK.md, which owns the shape. Its floor table is the part checks/check.mjs reads: six classes of risk, each answered with a command, a reasoned not applicable, or a named manual check with a defer: marker. Fill that table as you research, because it is what step 3 has to satisfy.

stack is a skill published in the GitHub repository Tradebaas/Groundwork (2 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,853 tokens. 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 2026-08-31.
