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 | $0.00051 | $0.00630 |
| Opus 5.5 | $0.00020 | $0.00252 |
| Sonnet 5.5 | $0.00010 | $0.00126 |
| Haiku 4.5 | $0.00005 | $0.00063 |
Grade A, and why
native-nostalgia-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 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.
This is a copy
100% identical to native-nostalgia-stack — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Native nostalgia stack
Apply only the contract material to the requested work. Project AGENTS and docs
own implementation rules and exact commands; project-structure/SKILL.md owns
language-neutral layout and documentation.
Compiler and layout
- Use the project-pinned latest stable FPC and Delphi mode unless project docs explicitly choose another mode.
- Keep project-wide compiler directives in one shared include used by every unit.
- Put Pascal source under one root (
source/preferred), using namespaced filenames and a flat layout until a namespace becomes unwieldy. - Co-locate unit tests; keep delivered end-to-end corpora under root
tests/. - Put all ignored build output under root
build/. - Prefer executable InstantFPC for one-off Pascal scripts; use an existing task runner or dynamic language only when that is materially simpler.
Read references/code-style.md when writing or reviewing Pascal source.
Build contract
The project chooses the implementation but provides one root entry point:
- bare invocation performs a clean development build of all binaries;
- positional names select one or more binary targets;
- development is the default and a production flag selects release settings;
cleanis a target and can be combined with a target;- every binary lands under
build/.
Document the entry point, targets, and flags in docs/build-system.md; read it
before changing them.
Formatter and health contracts
One formatter/linter command rewrites Pascal by default and has a non-mutating
--check mode that exits non-zero on deviation. Project-specific style lives in
the tool and docs/code-style.md, not scattered config.
The codebase-health gate reports located duplication, per-function cyclomatic
and cognitive complexity, sortable file health, and complexity-times-churn
hotspots. Thresholds and ignores live in one root config; breaches exit
non-zero. Document the tool and thresholds in docs/tooling.md.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

native-nostalgia-stack is a skill published in the GitHub repository frostney/pascal-mcp-sdk (2 stars, last pushed 4d ago), licensed MIT. It adds 51 tokens to every session and 630 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to native-nostalgia-stack, differing in 17 lines, and is treated as a copy.
Other skills, from other repositories
add-export
Add a new subpath export to the @cyanheads/mcp-ts-core package. Use when creating a new public API surface that consumers import from a dedicated subpath (e.g., @cyanheads/mcp-ts-core/newutil).
fluent-development
This skill should be used when the user asks to "build a fluent app", "create a servicenow app in typescript", or mentions "servicenow sdk", "now-sdk", "fluent", "scoped app as code", or "pro-code development" — or when the working directory contains a now.config.json or .now.ts files.
quantum-vqe
A runnable guide to the variational quantum eigensolver (VQE), a quantum algorithm that estimates the lowest energy of a mathematical system by adjusting a parameterized circuit. It uses Pauli Hamiltonians, a specified circuit form, and SciPy optimization.
quantum-vqls
A runnable guide to the variational quantum linear solver (VQLS), a quantum method that estimates a solution to a system of linear equations by optimizing a parameterized circuit. It uses Qiskit and reports the numerical residual and why optimization stopped.
es5-compliance
Enforce ES5-only syntax for ServiceNow server-side scripts (Rhino engine) — convert const/let, arrow functions, template literals, destructuring, for-of, and async/await to ES5 equivalents.
rust-neckbeard
Dedalus Rust correctness and style rules. Use when writing, reviewing, or refactoring any Rust code in the host-agent, enclave, or packages/rust workspaces. Covers return-value naming, error design, mustuse, visibility, RAII, fail-closed, and all hard limits from style.md and rust.mdx.
