What is detect-tech-stack.template?

A technology-stack detector that examines a project and updates its configuration. A technology stack is the set of languages, frameworks, libraries, and tools used by an application.

Use it to re-detect the stack and update the configuration used by agents, skills, and hooks.

It refreshes project information after dependencies, frameworks, or versions change.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01144
Opus 5.5	$0.00000	$0.00458
Sonnet 5.5	$0.00000	$0.00229
Haiku 4.5	$0.00000	$0.00114

Security

Grade B, and why

detect-tech-stack.template scanned grade B with 1 finding 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex Runtime Compatibility

This prompt was authored for Claude-style slash workflows. In Codex runtime, adapt tool calls as follows:

AskUserQuestion => ask the user directly in chat.
WebSearch/WebFetch => use available web tools (search_query, open, find) and cite links.
Read/Write => use shell/filesystem tools in this workspace.
Claude-only MCP calls (for example Playwright MCP names) => use available equivalents or clearly state fallback.
Keep intent and output format identical; only adapt execution mechanics.

description: Re-run tech stack detection and update configuration

/detect-tech-stack - Tech Stack Analysis

Re-analyze the project's tech stack and update .claude/config/tech-stack.json.

Purpose

Issue #8: Tech stack detection previously only ran during terminal phase (ccasp init). This command allows re-running detection from within Claude CLI to:

Detect new dependencies added since initial setup
Update framework versions
Refresh configuration for agents, skills, and hooks

Execution Steps

Step 1: Read Current Tech Stack

cat .claude/config/tech-stack.json 2>/dev/null || echo "{}"

Save as previousStack for comparison.

Step 2: Detect Current Stack

Analyze the following files to build the new tech stack:

Package Managers:

package.json → Node.js/npm project
pyproject.toml or requirements.txt → Python project
Cargo.toml → Rust project
go.mod → Go project
pom.xml or build.gradle → Java project

Frontend Frameworks (from package.json):

react → React
vue → Vue.js
@angular/core → Angular
svelte → Svelte
next → Next.js
nuxt → Nuxt.js
vite → Vite bundler

Backend Frameworks:

express → Express.js
fastify → Fastify
@nestjs/core → NestJS
fastapi (Python) → FastAPI
django (Python) → Django
flask (Python) → Flask

Testing Frameworks:

jest → Jest
vitest → Vitest
playwright → Playwright
cypress → Cypress
pytest (Python) → Pytest

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.

detect-tech-stack.template is a command published in the GitHub repository evan043/claude-cli-advanced-starter-pack (61 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,144 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
