post-task

A cleanup step that runs when a coding task finishes. It can measure performance, save decisions, export learned patterns, and create a completion report.

In plain words
What is it for?
Use it after a task to inspect execution time and token use, find bottlenecks, save implementation choices and fixes, export patterns, or generate a report.
Why use it?
It makes the result easier to review and preserves information that may help with future tasks.

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

post-task 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.

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

hook post-task

Execute post-task cleanup, performance analysis, and memory storage.

Usage

npx claude-flow hook post-task [options]

Options

  • --task-id, -t <id> - Task identifier for tracking
  • --analyze-performance - Generate performance metrics (default: true)
  • --store-decisions - Save task decisions to memory
  • --export-learnings - Export neural pattern learnings
  • --generate-report - Create task completion report

Examples

Basic post-task hook

npx claude-flow hook post-task --task-id "auth-implementation"

With full analysis

npx claude-flow hook post-task -t "api-refactor" --analyze-performance --generate-report

Memory storage

npx claude-flow hook post-task -t "bug-fix-123" --store-decisions --export-learnings

Quick cleanup

npx claude-flow hook post-task -t "minor-update" --analyze-performance false

Features

Performance Analysis

  • Measures execution time
  • Tracks token usage
  • Identifies bottlenecks
  • Suggests optimizations

Decision Storage

  • Saves key decisions made
  • Records implementation choices
  • Stores error resolutions
  • Maintains knowledge base

Neural Learning

  • Exports successful patterns
  • Updates coordination models
  • Improves future performance
  • Trains on task outcomes

Report Generation

  • Creates completion summary
  • Documents changes made
  • Lists files modified
  • Tracks metrics achieved

Integration

This hook is automatically called by Claude Code when:

  • Completing a task
  • Switching to a new task
  • Ending a work session
  • After major milestones

Manual usage in agents:

# In agent coordination
npx claude-flow hook post-task --task-id "your-task-id" --analyze-performance true

Output

Returns JSON with:

{
  "taskId": "auth-implementation",
  "duration": 1800000,
  "tokensUsed": 45000,
  "filesModified": 12,
  "performanceScore": 0.92,
  "learningsExported": true,
  "reportPath": "/reports/task-auth-implementation.md"
}

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.

post-task is a command published in the GitHub repository ruvnet/RuView (92,079 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 545 tokens. 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.
