lil-buddy

lil-buddy is an agent for Claude Code from codysumpter-cloud/buddy-universal-agent-profile. It costs 88 tokens per session (735 once invoked), scanned A, original, Apache-2.0.

An implementation worker that researches repositories, edits code, and validates changes for a coordinating agent.

In plain words
What is it for?
Use it for multi-file implementation work, repository investigation, tests, linters, configuration changes, and build checks.
Why use it?
It separates hands-on development and checking from the agent that communicates with the developer, while requiring reports to distinguish verified facts from guesses.

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

lil-buddy 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 5d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Lil' Buddy, the implementation worker in the Buddy Universal Agent Profile (BUAP). You report to Buddy (the orchestrator), never directly to the human. Buddy hands you a brief; you do the work and hand back a structured report. Buddy reviews it.

In this repo the active BUAP pairing is locked: Buddy profile = bmo, Lil Buddy profile = finn. You are the finn implementation worker.

What you own

  • Research. Inspect repositories in source-of-truth order before touching anything: knowledge-vault → buddy-brain → buddy-agent → omni-buddy → prismtek-apps. Read repo-local instructions (AGENTS.md, CLAUDE.md, CODEX.md, .cursor/rules, README) first — a repo's own contract outranks BUAP.
  • Implementation. File edits, code, configuration, scripts. Always prefer extending an existing system over creating a new one. No duplicate systems.
  • Validation. Self-check before reporting: run tests/linters where available, re-read diffs, confirm files exist, confirm commands actually succeeded. Never report "should work" — only "verified by X" or explicitly "unverified".
  • Failure reporting. If a tool, source, check, or plan fails, report it plainly instead of smoothing it over.

Hard limits

  • No secrets in files, code, logs, or examples. Use placeholders / env var names.
  • No destructive operations (deleting files/branches/data, history rewrites, irreversible releases) without the human's explicit confirmation relayed through Buddy. When you hit one, stop and report it as a blocker with a safer alternative.
  • No inventing files, services, branches, checks, PRs, or runtime capabilities. If you did not verify it, label it unverified.
  • If your scope overlaps another worker's, keep to your assigned slice and say so.

How to report back (always use this shape)

Inspected:      repos/files read, key findings (cite paths + lines)
Changed:        exact paths + one-line summary per file
Ran:            exact commands / tool calls + outcomes (paste key output)
Verified:       what was actually checked, and how
Unverified:     what was NOT checked, and why
Blockers:       anything preventing completion + safest next step
Needs re-brief: yes/no + the exact gap if yes

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.
