complete

A task-completion command that marks a task finished in a JSON task file and updates related tasks that depended on it.

In plain words
What is it for?
Use it when finishing a task identified by an ID, especially in projects where tasks have dependencies or multiple task files.
Why use it?
It avoids manually changing task status, progress totals, timestamps, and dependency lists. It also shows which blocked tasks can now be started.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

complete 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 yesterday.

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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mark a task as complete and update all dependent task relationships.

Arguments:

  • task-id (required): The task ID to mark complete (e.g., TASK-001)
  • project-name (optional): Project name if multiple task files exist

Process

  1. Locate and validate

    • Find the task file (tasks/*.tasks.json or tasks/<project-name>.tasks.json)
    • Verify the task exists
    • Check current status (warn if already complete)
  2. Update task status

    • Set status to "complete"
    • Update metadata.last_updated timestamp
    • Recalculate metadata.completion_percentage
  3. Update dependent tasks

    • For each task that has this task in blocked_by:
      • Remove this task from their blocked_by array
      • If blocked_by becomes empty and status was "blocked", change to "not_started"
    • Track which tasks became unblocked
  4. Write updated file

    • Save the modified JSON to the task file
    • Preserve formatting
  5. Display results

Output Format

## Task Completed

**TASK-XXX:** <title>

Status: not_started -> complete

### Progress Update

- Completion: 45% -> 50% (10/20 tasks)
- Tasks unblocked: 2

### Newly Unblocked Tasks

The following tasks can now be started:

1. **TASK-AAA:** <title>
   - Priority: high
   - Complexity: M
   - Was waiting on: TASK-XXX

2. **TASK-BBB:** <title>
   - Priority: medium
   - Complexity: S
   - Was waiting on: TASK-XXX, TASK-YYY (TASK-YYY already complete)

### Recommended Next

Based on priority and dependencies:

1. **TASK-AAA** - High priority, medium complexity
2. **TASK-CCC** - High priority, small complexity

Run `/mission-control:next` for full recommendations.

Edge Cases

  • Task already complete: Warn but don't error
  • Task is blocked: Error - cannot complete a blocked task without completing blockers first
  • Task in progress: Allow completion (normal flow)
  • No tasks unblocked: Note that no new tasks were unblocked
  • All tasks complete: Congratulate user on completing the project!

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.

complete is a command published in the GitHub repository sequenzia/claude-plugins (2 stars, last pushed 7mo ago), licensed MIT. It adds 11 tokens to every session and 575 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 2026-08-31.
