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 | $0.00043 | $0.03981 |
| Opus 5.5 | $0.00017 | $0.01592 |
| Sonnet 5.5 | $0.00009 | $0.00796 |
| Haiku 4.5 | $0.00004 | $0.00398 |
Grade A, and why
tech-stack-typescript 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.
How it starts
The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tech Stack: TypeScript
Overview
TypeScript/JavaScript context for the workflow skills and review agents: commands, detection markers, the data-layer and framework rules that bite (React, React Native/Expo, Next.js, Tauri, Node), settings and scan recipes. Generic framework practice is assumed, not restated. JavaScript-only projects use the same skill; the type rules become recommendations.
When To Use
Loaded automatically when the active tech stack is typescript; never invoked directly.
Build & Test Commands
setup-bootstrap writes the detected package manager to .claude/tech-stack-pm; <pm> below is that value. Detection, first match wins:
if [ -f bun.lock ] || [ -f bun.lockb ]; then echo bun
elif [ -f pnpm-lock.yaml ]; then echo pnpm
elif [ -f yarn.lock ]; then echo yarn
else echo npm # package-lock.json, or package.json only
fi
- Install:
<pm> install - Type check (compile-equivalent):
<pm> run typecheckif defined inpackage.json, elsenpx tsc --noEmit --pretty false(ortsc -bfor project references) - Build:
<pm> run build(verifies full toolchain — bundler, type check, assets) - Test (batch):
<pm> test <path/to/file>or<pm> run test -- <pattern>(vitest/jest support filter flags; checkpackage.jsonscripts) - Test (full):
<pm> testor<pm> run test - Bounded output is the default. Pass
--reporter=dot(vitest) or--silent(jest) where the runner supports it. Batch checkpoints run these throughbash scripts/mtk-verify-run.sh --label <batch-id>-<step> -- <cmd>— the wrapper's bounded tail is the evidence, the log path is the receipt. - Format: see
## Format Command. - Lint:
<pm> run lintif defined, elsenpx eslint <path>ornpx biome check <path>based on project config
Tauri (when src-tauri/ exists): from src-tauri/, cargo check (fast) or cargo build, cargo test, cargo fmt, cargo clippy -- -D warnings; full app <pm> run tauri dev / <pm> run tauri build.
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.

tech-stack-typescript is a skill published in the GitHub repository moberghr/mtk-agent-toolkit (9 stars, last pushed 8d ago), licensed MIT. It adds 43 tokens to every session and 3,981 once invoked, about $0.0002 per session on Opus 5.5. 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.
