tda: Skill for Claude Code

.agents/skills/tda-thread-dump-analysis/SKILL.md

tda-thread-dump-analysis is a skill for Claude Code, Codex from irockel/tda. It costs 81 tokens per session (1,577 once invoked), scanned A, original, LGPL-2.1.

A Java thread-dump analysis tool for investigating problems inside running Java programs. A thread dump is a snapshot showing what each program thread was doing at a particular time.

In plain words
What is it for?
Use it with thread dumps, jstack output, or related log files to investigate deadlocks, threads waiting on one another, CPU spikes, virtual-thread carrier pinning, and SMR zombie threads.
Why use it?
It helps diagnose a hung or overloaded Java virtual machine by examining evidence from thread-dump files instead of relying only on symptoms.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is irockel/tda's own configuration. It tells Claude Code and Codex how to work on tda 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 tda 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

tda-thread-dump-analysis 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/tda_client.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Changes

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.
