gsd-quick

gsd-quick is a command for Claude Code from mrmyothet/zach-hair-studio. It costs 24 tokens per session (1,735 once invoked), scanned A, a copy of gsd:quick, MIT.

A shorter development workflow for well-understood tasks, with atomic commits and project-state tracking but fewer optional review steps.

In plain words
What is it for?
Use it for quick implementation tasks, with optional discussion, research, plan checking, and verification enabled by flags.
Why use it?
It avoids the full planning and research process when the task is clear, while keeping a record of the work.

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-quick 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 7d 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quick mode is the same system with a shorter path:

  • Spawns gsd-planner (quick mode) + gsd-executor(s)
  • Quick tasks live in .planning/quick/ separate from planned phases
  • Updates STATE.md "Quick Tasks Completed" table (NOT ROADMAP.md)

Default: Skips research, discussion, plan-checker, verifier. Use when you know exactly what to do.

--discuss flag: Lightweight discussion phase before planning. Surfaces assumptions, clarifies gray areas, captures decisions in CONTEXT.md. Use when the task has ambiguity worth resolving upfront.

--full flag: Enables the complete quality pipeline — discussion + research + plan-checking + verification. One flag for everything.

--validate flag: Enables plan-checking (max 2 iterations) and post-execution verification only. Use when you want quality guarantees without discussion or research.

--research flag: Spawns a focused research agent before planning. Investigates implementation approaches, library options, and pitfalls for the task. Use when you're unsure of the best approach.

Granular flags are composable: --discuss --research --validate gives the same result as --full.

Subcommands:

  • list — List all quick tasks with status
  • status <slug> — Show status of a specific quick task
  • resume <slug> — Resume a specific quick task by slug

<execution_context> @/home/myothet/repos/vct/zach-hair-studio/landing-page/.claude/gsd-core/workflows/quick.md </execution_context>

Context files are resolved inside the workflow (init quick) and delegated via <files_to_read> blocks.

Parse $ARGUMENTS for subcommands FIRST:

  • If $ARGUMENTS starts with "list": SUBCMD=list
  • If $ARGUMENTS starts with "status ": SUBCMD=status, SLUG=remainder (strip whitespace, sanitize)
  • If $ARGUMENTS starts with "resume ": SUBCMD=resume, SLUG=remainder (strip whitespace, sanitize)
  • Otherwise: SUBCMD=run, pass full $ARGUMENTS to the quick workflow as-is

Slug sanitization (for status and resume): Strip any characters not matching [a-z0-9-]. Reject slugs longer than 60 chars or containing .. or /. If invalid, output "Invalid session slug." and stop.

LIST subcommand

When SUBCMD=list:

ls -d .planning/quick/*/  2>/dev/null

For each directory found:

  • Check if PLAN.md exists
  • Check if SUMMARY.md exists; if so, read status from its frontmatter via:
    gsd-tools query frontmatter.get .planning/quick/{dir}/SUMMARY.md status
    
  • Determine directory creation date: stat -f "%SB" -t "%Y-%m-%d" (macOS) or stat -c "%w" (Linux); fall back to the date prefix in the directory name (format: YYYYMMDD- prefix)
  • Derive display status:
    • SUMMARY.md exists, frontmatter status=complete → complete ✓
    • SUMMARY.md exists, frontmatter status=incomplete OR status missing → incomplete
    • SUMMARY.md missing, dir created <7 days ago → in-progress
    • SUMMARY.md missing, dir created ≥7 days ago → abandoned? (>7 days, no summary)

SECURITY: Directory names are read from the filesystem. Before displaying any slug, sanitize: strip non-printable characters, ANSI escape sequences, and path separators using: name.replace(/[^\x20-\x7E]/g, '').replace(/[/\\]/g, ''). Never pass raw directory names to shell commands via string interpolation.

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.
