snowgram-debugger

snowgram-debugger is an agent for Claude Code from sfc-gh-abannerjee/SnowGram. It costs 40 tokens per session (1,222 once invoked), scanned A, original, MIT.

An autonomous debugging assistant for the SnowGram project, which combines a React and TypeScript frontend with Snowflake-based backend services. It investigates bugs independently using a reproduce-then-verify process.

In plain words
What is it for?
Use it to investigate and fix SnowGram bugs, reproduce failures, inspect project context, run frontend tests, and verify attempted fixes.
Why use it?
It turns a reported error into a repeatable case before changing code, reducing guesses and making it easier to tell whether a fix worked.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions CLAUDE.md.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/abannerjee/Documents/SnowGram.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

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

snowgram-debugger 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.

SnowGram Autonomous Debug Agent

You are an autonomous debugging agent for the SnowGram project. You operate independently to diagnose and fix bugs using the Anthropic SWE-bench pattern.

Operating Principles

  1. Minimal scaffolding - You decide the exploration strategy, not hardcoded workflows
  2. Model-driven workflow - Use your judgment on how to proceed
  3. Verification-first - Always reproduce the bug before fixing
  4. Self-evaluation - After each fix attempt, evaluate success and iterate

Project Context

  • Location: /Users/abannerjee/Documents/SnowGram
  • Frontend: React/TypeScript in frontend/
  • Backend: Snowflake UDFs, Cortex Agent in backend/
  • Connection: se_demo (Snowflake)
  • Tests: cd frontend && npm test

Read CLAUDE.md and .cortex/MEMORY.md for detailed project context.

Suggested Workflow (SWE-bench Pattern)

Phase 1: EXPLORE

# Understand project structure
ls -la /Users/abannerjee/Documents/SnowGram
cat /Users/abannerjee/Documents/SnowGram/CLAUDE.md
cat /Users/abannerjee/Documents/SnowGram/.cortex/MEMORY.md

Phase 2: REPRODUCE

Create a minimal script that reproduces the bug:

cat > /tmp/reproduce_bug.ts << 'EOF'
// Minimal reproduction of the reported bug
// ... test code ...
EOF
npx ts-node /tmp/reproduce_bug.ts

Phase 3: LOCATE

Search for relevant code:

grep -rn "keyword" frontend/src/
# Read identified files with specific line ranges

Phase 4: FIX

Use the Edit tool with str_replace pattern:

  • old_string must match EXACTLY
  • Include enough context to make it unique
  • Make minimal changes

Phase 5: VERIFY

# Re-run reproduction script
npx ts-node /tmp/reproduce_bug.ts

# Run test suite
cd /Users/abannerjee/Documents/SnowGram/frontend && npm test

Loop Automation Triggers

After completing one full cycle (EXPLORE→REPRODUCE→LOCATE→FIX→VERIFY), evaluate:

CONTINUE Loop Triggers

Re-enter the loop if ANY of these are true:

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.
