snowgram-debugger

snowgram-debugger is a skill for Claude Code, Codex from sfc-gh-abannerjee/SnowGram. It costs 55 tokens per session (2,906 once invoked), scanned A, original, MIT.

An automated debugging workflow for the SnowGram codebase, with separate paths for layout problems, agent behavior, test failures, and other bugs.

In plain words
What is it for?
Use it to analyze bugs, route layout or agent issues to specialized procedures, investigate failing tests, and verify fixes.
Why use it?
It gives investigations a repeatable starting point when code behaves unexpectedly or tests fail.

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

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.

Good fit Use it to analyze bugs, route layout or agent issues to specialized procedures, investigate failing tests, and verify fixes.

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, Codex.

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 8d 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 Loop

Architecture: Anthropic SWE-bench Agent Pattern (Jan 2025) + Claude Code Skills (2026) Principle: Minimal scaffolding, maximum model control, deterministic verification


⚡ Entry Point: Route to Correct Sub-Skill

Load this decision tree FIRST before proceeding:

ANALYZE user's bug description:

IF mentions "lane", "badge", "layout", "section", "streaming diagram", "nodes scattered":
    → LOAD $lane-layout-debugger (specialized for layout issues)
    → EXIT this skill
    
ELIF mentions "agent", "Cortex Agent", "response", "tool call", "semantic model":
    → Continue below with agent-specific patterns
    
ELIF mentions "test", "npm test", "vitest", "jest", "failing test":
    → Continue below with test debugging patterns
    
ELSE:
    → Continue below with general SWE-bench pattern

Design Philosophy (2025-2026 Best Practices)

Based on Anthropic's SWE-bench state-of-the-art agent (49% solve rate):

"Our design philosophy was to give as much control as possible to the language model itself, and keep the scaffolding minimal."

Principle Implementation
Minimal scaffolding No complex orchestration - single agent with tools
Model-driven workflow Agent decides exploration strategy, not hardcoded
Bash + Edit tools Same tools that achieved SOTA on SWE-bench
Context awareness Uses CLAUDE.md + MEMORY.md for project context
Verification-first Create reproduce script, confirm fix works

Entry Point: Describe the Bug

$snowgram-debugger

Input: Natural language description of the problem
- "Lane badges not appearing in streaming diagram"
- "Agent returns 'Diagram updated' without code"  
- "Tests failing after dependency update"
- "Component not rendering in dark mode"

Autonomous Workflow (SWE-bench Pattern)

The agent follows this suggested approach (but can adapt as needed):

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.

snowgram-debugger is a skill published in the GitHub repository sfc-gh-abannerjee/SnowGram (2 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 2,906 once invoked, about $0.0003 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.
