gsd:debug

A command for investigating software bugs with a saved debugging session. It gathers symptoms, tests possible causes, and can continue an investigation later.

In plain words
What is it for?
Use it to diagnose bugs, apply a structured investigation, list or inspect active sessions, continue a session, or run diagnosis without changing the code.
Why use it?
It keeps debugging organised when finding the cause requires reading code, testing hypotheses, or working across multiple sessions.

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

gsd:debug 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 2d 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 — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orchestrator role: Gather symptoms, spawn gsd-debugger agent, handle checkpoints, spawn continuations.

Why subagent: Investigation burns context fast (reading files, forming hypotheses, testing). Fresh 200k context per investigation. Main context stays lean for user interaction.

Flags:

  • --diagnose — Diagnose only. Find root cause without applying a fix. Returns a structured Root Cause Report. Use when you want to validate the diagnosis before committing to a fix.

Subcommands:

  • list — List all active debug sessions
  • status <slug> — Print full summary of a session without spawning an agent
  • continue <slug> — Resume a specific session by slug

<available_agent_types> Valid GSD subagent types (use exact names — do not fall back to 'general-purpose'):

  • gsd-debug-session-manager — manages debug checkpoint/continuation loop in isolated context
  • gsd-debugger — investigates bugs using scientific method </available_agent_types>

Parse subcommands and flags from $ARGUMENTS BEFORE the active-session check:

  • If $ARGUMENTS starts with "list": SUBCMD=list, no further args
  • If $ARGUMENTS starts with "status ": SUBCMD=status, SLUG=remainder (trim whitespace)
  • If $ARGUMENTS starts with "continue ": SUBCMD=continue, SLUG=remainder (trim whitespace)
  • If $ARGUMENTS contains --diagnose: SUBCMD=debug, diagnose_only=true, strip --diagnose from description
  • Otherwise: SUBCMD=debug, diagnose_only=false

Check for active sessions (used for non-list/status/continue flows):

ls .planning/debug/*.md 2>/dev/null | grep -v resolved | head -5

0. Initialize Context

INIT=$(node "/tmp/pomodoro-bench/gsd/.claude/get-shit-done/bin/gsd-tools.cjs" state load)
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi

Extract commit_docs from init JSON. Resolve debugger model:

debugger_model=$(node "/tmp/pomodoro-bench/gsd/.claude/get-shit-done/bin/gsd-tools.cjs" resolve-model gsd-debugger --raw)

Read TDD mode from config:

TDD_MODE=$(node "/tmp/pomodoro-bench/gsd/.claude/get-shit-done/bin/gsd-tools.cjs" config-get tdd_mode 2>/dev/null || echo "false")

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.

gsd:debug is a command published in the GitHub repository kryptobaseddev/cleo (160 stars, last pushed 12d ago), licensed MIT. It adds 14 tokens to every session and 2,302 once invoked, about $0.0001 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 2026-08-30.
