Creek-Vault: Agent for Claude Code

.claude/agents/implementation-specialist.md

implementation-specialist is an agent for Claude Code from Geoffe-Ga/Creek-Vault. It costs 72 tokens per session (1,111 once invoked), scanned A, original, no licence file.

A coding agent that implements a planned change by first working from failing tests, writing production code until they pass, and then refactoring the result.

In plain words
What is it for?
Use it to implement pipeline stages, command-line commands, or MCP tools, and to review the resulting code for quality.
Why use it?
It provides a test-led path for turning an approved plan into code while checking correctness and maintainability during the work.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is Geoffe-Ga/Creek-Vault's own configuration. It tells Claude Code how to work on Creek-Vault itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Creek-Vault configures →

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

implementation-specialist 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 4d 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.

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.
