openarg_backend: Command for Claude Code

.claude/commands/debug-pipeline.md

debug-pipeline is a command for Claude Code from colossus-lab/openarg_backend. It costs 0 tokens per session (1,001 once invoked), scanned A, original, MIT.

A checklist for diagnosing a backend pipeline that scrapes data, creates embeddings, collects results, and analyzes them. It checks databases, Redis, migrations, environment variables, workers, adapters, and task handoffs.

In plain words
What is it for?
Use it to investigate failures in catalog scraping, dataset storage, embedding jobs, Celery workers, portal adapters, or pipeline connectivity.
Why use it?
It narrows down whether a failure comes from infrastructure, a scraper, a background task, or the data passed between stages.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: positional $N argument.

This is colossus-lab/openarg_backend's own configuration. It tells Claude Code how to work on openarg_backend itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openarg_backend configures →

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

debug-pipeline 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.

Debug backend pipeline: $ARGUMENTS

Diagnose the described problem in the scraper → embedding → collector → analyst pipeline. Follow this checklist:

Base infrastructure

  • PostgreSQL running: make db.up or check docker (docker ps | grep postgres)
  • Redis running: verify connectivity on port 6381
  • Migrations applied: make db.migrate
  • Environment variables: OPENAI_API_KEY, DATABASE_URL, CELERY_BROKER_URL
  • Workers active: check in Flower (make flower → http://localhost:5556)

Scraper (src/app/infrastructure/celery/tasks/scraper_tasks.py)

  • scrape_catalog(portal) receives a valid portal (datos_gob_ar, caba, etc.)
  • The corresponding IDataSource adapter is registered in Dishka
  • fetch_catalog() returns CatalogEntry[] — is the CKAN portal responding?
  • Upsert to datasets works (check UNIQUE constraint on source_id + portal)
  • Dispatches index_dataset_embedding for each dataset
  • If failing: check worker-scraper logs, verify HTTPX timeout

Embedding (src/app/infrastructure/celery/tasks/embedding_tasks.py + scraper_tasks.py)

  • index_dataset_embedding(dataset_id) receives a valid UUID
  • The dataset exists in the datasets table
  • 3 chunks are generated: main, columns, contextual
  • OpenAI embedding API responds (verify OPENAI_API_KEY)
  • Chunks are saved in dataset_chunks with 1536-dim embedding
  • HNSW index works: SELECT * FROM dataset_chunks ORDER BY embedding <=> $1 LIMIT 5
  • If failing: check retries (max 3), review worker-embedding logs

Collector (src/app/infrastructure/celery/tasks/collector_tasks.py)

  • collect_dataset(dataset_id) downloads the file from download_url
  • Format is supported (CSV, JSON, XLSX, XLS)
  • Pandas parses correctly (check encoding, separators)
  • Cache table cache_{id} is created in PostgreSQL
  • cached_datasets is updated: status downloading → ready
  • datasets.is_cached = true and row_count updated
  • Row limit: 500k max
  • If failing: check download URL, file format, worker-collector logs

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.

debug-pipeline is a command published in the GitHub repository colossus-lab/openarg_backend (150 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,001 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.
