intel-mastery

intel-mastery is a skill for Claude Code from mgd34msu/goodvibes-plugin. It costs 88 tokens per session (1,496 once invoked), scanned A, original, MIT.

A guide to 15 code-analysis tools that understand structure, including code search, safe deletion, API checks, database schemas, user-interface components, and dependency relationships. It explains when to use these tools instead of simpler built-in commands.

In plain words
What is it for?
Use it while exploring a codebase, checking APIs or database schemas, tracing components and hooks, analyzing layouts, scaffolding code, or making structure-aware edits.
Why use it?
It helps you choose the right inspection method and avoid mistakes such as deleting code that is still referenced or resolving paths against the wrong directory.

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.

Security

Grade A, and why

intel-mastery 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 6d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

intel-mastery

The goodvibes intel server ships 15 tools. They are opt-in, not mandatory. Reach for one on the operations it is actually measured to beat a native tool on, among them structure-aware search, safe-delete reference checking, and API, schema, and component analysis. Do not force one where a native tool is simpler, or where intel does not cover the case at all.

Fourteen of the fifteen only read. The exception is structural_edit, which writes, and it is covered at the end of this skill.

The contract every filesystem tool follows

Every tool that touches the filesystem takes base_path and echoes resolved_path (absolute) for every file in the response. Pass base_path explicitly. A relative path resolved without one still works, but the response carries a warning field telling you it resolved against the server's own working directory, which may not be what you meant.

Every response is an envelope: { success, data, error?, warning?, meta }. meta.token_estimate is computed from the actual rendered response, not a guess. If a cap trimmed the payload, meta.truncated is true and meta.effective_caps names which cap did it. A response that silently drops content without saying so is a bug, not intended behavior.

code_read: outline or lines, not everything

Two extract modes: outline (structure: exports, top-level declarations, no bodies) and lines/range (actual content, optionally with line numbers via include_line_numbers). Start with outline when you're orienting yourself in a file you haven't read yet; only pull lines for the specific ranges you need to act on. Batch multiple files in one call. Each entry in the response is keyed by the request entry, not by path, so two requests for the same path never collide.

code_grep: the crown jewel, with honest caps

Supports count_only, files_only, and full match output, with real .gitignore respect (not a partial implementation). Every cap (max_results, max_total_matches) is echoed in effective_caps in every output format, including count_only. If you get a count, trust it; if results were capped, truncated says so. Use count_only first to gauge scope on a broad pattern before pulling full matches.

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.

intel-mastery is a skill published in the GitHub repository mgd34msu/goodvibes-plugin (6 stars, last pushed 13d ago), licensed MIT. It adds 88 tokens to every session and 1,496 once invoked, about $0.0004 per session on Opus 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.
