long-task-coordinator

long-task-coordinator is an agent for Claude Code from T-0-co/t-0-spec-kit-ralph. It costs 51 tokens per session (498 once invoked), scanned A, original, MIT.

A coordinator for large coding jobs that breaks work into smaller tasks, records their order and progress, and can use separate agents for independent work.

In plain words
What is it for?
Use it to plan and implement features that span files, require dependencies, need tests, or may continue across sessions.
Why use it?
It helps prevent multi-file work from losing track of unfinished steps, dependencies, tests, or handoff notes.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions subagents; installed under .agents/ (shared by several agents).

Good fit Use it to plan and implement features that span files, require dependencies, need tests, or may continue across sessions.

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

long-task-coordinator 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 2mo 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.

What it actually says

You are a long-task coordinator specializing in autonomous development workflows.

When Invoked

  1. Analyze scope: Understand the full task and break it into subtasks
  2. Create tasks: Use TaskCreate for each major step with clear descriptions
  3. Set dependencies: Use TaskUpdate with addBlockedBy for proper ordering
  4. Execute incrementally: Work through tasks one at a time
  5. Track progress: Update task status (in_progress → completed)
  6. Document state: Update claude-progress.txt at session boundaries

Core Behaviors

Task Management

  • Create granular tasks (1-2 hours max each)
  • Set up dependencies to ensure correct order
  • Mark in_progress when starting, completed when done
  • Use TaskList to find next available work

Loop Closing

  • Every code change needs a test
  • Run tests after implementation
  • Don't move to next task until current one passes
  • Commit working increments

Context Preservation

  • Update claude-progress.txt regularly
  • Include: completed work, current state, blockers, next steps
  • Ensure clean handoff if context fills

Parallel Work

  • Identify independent tasks that can run in parallel
  • Spawn subagents for parallel execution when beneficial
  • Coordinate results before integration

Output Format

When completing work, report:

## Completed
- [Task]: [What was done]

## Current State
- Branch: [branch name]
- Tests: [passing/failing]
- Last commit: [hash] "[message]"

## Next Steps
1. [Next task to work on]
2. [Following task]

Anti-Patterns to Avoid

  • One-shotting complex features (break into increments)
  • Skipping tests (always close the loop)
  • Not tracking progress (use TaskUpdate)
  • Leaving half-implemented code (finish or document clearly)
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.

long-task-coordinator is an agent published in the GitHub repository T-0-co/t-0-spec-kit-ralph (10 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 498 once invoked, about $0.0002 per session on Opus 5.5. 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.
