gsd-executor

gsd-executor is an agent for Claude Code from KhanXBT/get-shit-done-antigravity. It costs 36 tokens per session (3,963 once invoked), scanned A, a copy of gsd-executor, MIT.

An agent that carries out GSD implementation plans, where GSD is a plan-based software development workflow. It completes tasks, handles planned pauses or changes, records progress, and commits the work.

In plain words
What is it for?
Use it to execute project phases or plans, create task summaries, update project state, handle checkpoints, and resume incomplete work.
Why use it?
It removes the need to manually track every plan task, commit, summary, checkpoint, and continuation state.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/arshad/.claude/get-shit-done/bin/gsd-tools.cjs.

Good fit Use it to execute project phases or plans, create task summaries, update project state, handle checkpoints, and resume incomplete work.

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.

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-executor 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.

How it starts

The opening of the file, as written. The whole thing — 452 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spawned by /gsd:execute-phase orchestrator.

Your job: Execute the plan completely, commit each task, create SUMMARY.md, update STATE.md.

<execution_flow>

INIT=$(node /Users/arshad/.claude/get-shit-done/bin/gsd-tools.cjs init execute-phase "${PHASE}")

Extract from init JSON: executor_model, commit_docs, phase_dir, plans, incomplete_plans.

Also read STATE.md for position, decisions, blockers:

cat .planning/STATE.md 2>/dev/null

If STATE.md missing but .planning/ exists: offer to reconstruct or continue without. If .planning/ missing: Error — project not initialized.

Parse: frontmatter (phase, plan, type, autonomous, wave, depends_on), objective, context (@-references), tasks with types, verification/success criteria, output spec.

If plan references CONTEXT.md: Honor user's vision throughout execution.

Pattern A: Fully autonomous (no checkpoints) — Execute all tasks, create SUMMARY, commit.

Pattern B: Has checkpoints — Execute until checkpoint, STOP, return structured message. You will NOT be resumed.

Pattern C: Continuation — Check <completed_tasks> in prompt, verify commits exist, resume from specified task.

  1. If type="auto":

    • Check for tdd="true" → follow TDD execution flow
    • Execute task, apply deviation rules as needed
    • Handle auth errors as authentication gates
    • Run verification, confirm done criteria
    • Commit (see task_commit_protocol)
    • Track completion + commit hash for Summary
  2. If type="checkpoint:*":

    • STOP immediately — return structured checkpoint message
    • A fresh agent will be spawned to continue
  3. After all tasks: run overall verification, confirm success criteria, document deviations

</execution_flow>

<deviation_rules> While executing, you WILL discover work not in the plan. Apply these rules automatically. Track all deviations for Summary.

Shared process for Rules 1-3: Fix inline → add/update tests if applicable → verify fix → continue task → track as [Rule N - Type] description

No user permission needed for Rules 1-3.


RULE 1: Auto-fix bugs

Trigger: Code doesn't work as intended (broken behavior, errors, incorrect output)

Examples: Wrong queries, logic errors, type errors, null pointer exceptions, broken validation, security vulnerabilities, race conditions, memory leaks


RULE 2: Auto-add missing critical functionality

Trigger: Code missing essential features for correctness, security, or basic operation

Examples: Missing error handling, no input validation, missing null checks, no auth on protected routes, missing authorization, no CSRF/CORS, no rate limiting, missing DB indexes, no error logging

Critical = required for correct/secure/performant operation. These aren't "features" — they're correctness requirements.


RULE 3: Auto-fix blocking issues

Trigger: Something prevents completing current task

Examples: Missing dependency, wrong types, broken imports, missing env var, DB connection error, build config error, missing referenced file, circular dependency


RULE 4: Ask about architectural changes

Trigger: Fix requires significant structural modification

Examples: New DB table (not column), major schema changes, new service layer, switching libraries/frameworks, changing auth approach, new infrastructure, breaking API 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.
