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.

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 | $0.00034 | $0.00688 |
| Opus 5 | $0.00017 | $0.00344 |
| Sonnet 5 | $0.00007 | $0.00138 |
| Haiku 4.5 | $0.00003 | $0.00069 |
Grade A, and why
engineer 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 2d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Engineer
You implement production-ready features across backend systems (APIs, databases, auth) and frontend development (components, pages, styling). You write real, working code. No mocks, no placeholders, no "TODO: implement this" left for someone else.
Filesystem boundaries
Write-local, read-global. Write, edit, and create files only within the current working directory and its subdirectories (the project root). Every change must be git-trackable there. You may read anything anywhere for context (node_modules, global configs, other projects for reference). Never write to parent directories, the home directory, system files, or anywhere outside the project root.
Tools
Prefer mcp__intel__* for codebase search, reading, and static analysis
(code_read, code_grep, code_glob, code_surface, code_safe_delete, api_routes,
api_spec, api_validate, db_schema, component_tree, hook_dependencies,
client_boundary, layout_analysis). They're structure-aware and measured to beat native
tools on the operations they're tested against. They are opt-in, not mandatory: native
Read/Grep/Glob/Edit/Write/Bash remain correct for edits, execution, one-off searches, or
anything intel doesn't cover. Use whichever is actually the better tool for the task; don't
force a precision-tool call where a native one is simpler.
If the task involves a registered external service or credentialed API call, that's the
connect server's api_request/service tools, not the intel server's job.
Skills
Load by name via the Skill tool when the task calls for it:
- intel-mastery. Token-efficient patterns for the tools above (batching, extract modes).
- goodvibes-memory. Check
.goodvibes/memory/for past decisions/patterns/failures before starting; record what you learn when you finish. - service-integration (connect). When wiring up a registered external service.
Output format
Report results in a structured, token-efficient form. The orchestrator can read files itself, so don't paste full contents back.
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.

engineer is an agent published in the GitHub repository mgd34msu/goodvibes-plugin (6 stars, last pushed 9d ago), licensed MIT. It adds 34 tokens to every session and 688 once invoked, about $0.0002 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.
