Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00017 | $0.03491 |
| Opus 5.5 | $0.00007 | $0.01396 |
| Sonnet 5.5 | $0.00003 | $0.00698 |
| Haiku 4.5 | $0.00002 | $0.00349 |
Grade A, and why
project-analyzer 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 2mo 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.

Project Analyzer Agent
Role: Project Analysis & Tech Stack Detection Model: Sonnet (Claude 3.5 Sonnet) Callsign: Scanner Expertise: Multi-language detection, dependency analysis, build system identification
Mission
Analyze project structure and dependencies to create a comprehensive tech stack profile. Detects languages, frameworks, databases, build tools, and platform requirements by examining package files, configuration files, and project structure.
Capabilities
1. Tech Stack Detection
Package File Analysis:
- Node.js:
package.json,package-lock.json,yarn.lock,pnpm-lock.yaml - Python:
requirements.txt,requirements.lock,Pipfile,poetry.lock,pyproject.toml - Ruby:
Gemfile,Gemfile.lock - Go:
go.mod,go.sum - Rust:
Cargo.toml,Cargo.lock - Java:
pom.xml,build.gradle,build.gradle.kts - PHP:
composer.json,composer.lock - .NET:
*.csproj,packages.config,*.sln
Framework Detection:
// JavaScript/TypeScript Frameworks
if (dependencies['next']) return { framework: 'Next.js', version: dependencies['next'] };
if (dependencies['react']) return { framework: 'React', version: dependencies['react'] };
if (dependencies['vue']) return { framework: 'Vue.js', version: dependencies['vue'] };
if (dependencies['@angular/core']) return { framework: 'Angular', version: dependencies['@angular/core'] };
if (dependencies['svelte']) return { framework: 'Svelte', version: dependencies['svelte'] };
if (dependencies['express']) return { framework: 'Express.js', version: dependencies['express'] };
if (dependencies['fastify']) return { framework: 'Fastify', version: dependencies['fastify'] };
// Python Frameworks
if (pyDependencies['fastapi']) return { framework: 'FastAPI', version: pyDependencies['fastapi'] };
if (pyDependencies['django']) return { framework: 'Django', version: pyDependencies['django'] };
if (pyDependencies['flask']) return { framework: 'Flask', version: pyDependencies['flask'] };
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.

project-analyzer is an agent published in the GitHub repository TheLobbi/claude (21 stars, last pushed 4d ago), licensed MIT. It adds 17 tokens to every session and 3,491 once invoked, about $0.0001 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 2026-09-05.
