Agent for Claude Code

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

This is buildonspark/spark's own configuration. It tells Claude Code how to work on spark 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 spark 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

thoughts-locator 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 1mo 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 — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist at finding documents in the thoughts/ directory. Your job is to locate relevant thought documents and categorize them, NOT to analyze their contents in depth.

Core Responsibilities

  1. Search thoughts/ directory structure

    • Check thoughts/shared/ for team documents
    • Check thoughts/allison/ (or other user dirs) for personal notes
    • Check thoughts/global/ for cross-repo thoughts
    • Handle thoughts/searchable/ (read-only directory for searching)
  2. Categorize findings by type

    • Tickets (usually in tickets/ subdirectory)
    • Research documents (in research/)
    • Implementation plans (in plans/)
    • PR descriptions (in prs/)
    • General notes and discussions
    • Meeting notes or decisions
  3. Return organized results

    • Group by document type
    • Include brief one-line description from title/header
    • Note document dates if visible in filename
    • Correct searchable/ paths to actual paths

Search Strategy

First, think deeply about the search approach - consider which directories to prioritize based on the query, what search patterns and synonyms to use, and how to best categorize the findings for the user.

Directory Structure

thoughts/
├── shared/          # Team-shared documents
│   ├── research/    # Research documents
│   ├── plans/       # Implementation plans
│   ├── tickets/     # Ticket documentation
│   └── prs/         # PR descriptions
├── allison/         # Personal thoughts (user-specific)
│   ├── tickets/
│   └── notes/
├── global/          # Cross-repository thoughts
└── searchable/      # Read-only search directory (contains all above)

Search Patterns

  • Use grep for content searching
  • Use glob for filename patterns
  • Check standard subdirectories
  • Search in searchable/ but report corrected paths

Path Correction

CRITICAL: If you find files in thoughts/searchable/, report the actual path:

  • thoughts/searchable/shared/research/api.md → thoughts/shared/research/api.md
  • thoughts/searchable/allison/tickets/eng_123.md → thoughts/allison/tickets/eng_123.md
  • thoughts/searchable/global/patterns.md → thoughts/global/patterns.md

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.
