A codebase analysis tool that examines a project's languages, structure, coding habits, and recurring patterns, then records the findings in a .vibeflow directory. It can analyze the whole project, selected folders, or a related dependency repository.

Use it when setting up work on an unfamiliar repository, refreshing documentation after major changes, investigating one module, or recording patterns from a satellite repository.

It gives a coding agent durable project-specific context instead of making it rediscover conventions each time. Interactive review can also remove incorrect findings before they are saved.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add pe-menezes/vibeflow --skill analyze

Clone the repo

git clone --depth 1 https://github.com/pe-menezes/vibeflow

Made for: Claude Code.

Or install vibeflow, the plugin that ships this one along with the rest of its 10 skills, 1 agent.

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	$0.00081	$0.06361
Opus 5	$0.00041	$0.03180

Security

Grade C, and why

analyze scanned grade C 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 596 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Description and examples

What it does: Scans the codebase and generates (or updates) .vibeflow/: index, conventions, and one pattern doc per significant pattern. Use once for project setup, then after big changes or to deep-dive into a module.

Examples:

analyze — First run or incremental (only re-analyzes what changed since last run).
analyze --fresh — Rebuild everything from scratch; ignore existing .vibeflow/.
analyze --scope src/app — Deep-dive into src/app only; requires .vibeflow/ to already exist. Enriches pattern docs with examples from that module.
analyze --interactive — Run analysis with interactive review: validate patterns, remove false positives, add tribal knowledge before saving.
analyze --fresh --interactive — Full rebuild with interactive review.
analyze --satellite https://github.com/org/design-system — Analyze a dependency repo, keep only patterns your code uses, merge into .vibeflow/patterns/satellite-<name>/.

Language

Detect the language of the user's conversation context. Write ALL output in that same language. Technical terms in English are acceptable regardless of the detected language. Section names in generated .vibeflow/ files may be in English (they are technical), but all descriptive text, analyses, observations, and final user reports should be in the detected language.

Web Search Policy

Use WebSearch and WebFetch only when local context (.vibeflow/, codebase, git history) is insufficient — an unfamiliar framework or API. Local first.

Perform a deep, adaptive analysis of this codebase. The goal is curated pattern documentation that every future spec, prompt pack, and audit uses to keep implementations on the project's real conventions.

Phase 0: Detect mode

Read .vibeflow/index.md directly by its path. Search, grep, and glob respect .gitignore, so they miss the directory and report it as absent.

Then read any flags in the user's current request (--fresh, --scope <path>, --interactive, --satellite <url>) and check whether git is available here.

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.

analyze is a skill published in the GitHub repository pe-menezes/vibeflow (29 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 6,361 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
