Huntable-CTI-Studio: Skill for Claude Code

.claude/skills/source-healing/SKILL.md

source-healing is a skill for Claude Code from dfirtnt/Huntable-CTI-Studio. It costs 155 tokens per session (2,415 once invoked), scanned A, original, MIT.

A guided process for diagnosing and repairing CTI sources in Huntable CTI Studio. CTI means cyber-threat intelligence, such as reports about security threats; a source may be a feed or website that supplies those reports.

In plain words
What is it for?
Use it to investigate sources that collect no articles or have repeated fetch failures. It proposes one fix at a time, requires human approval, and saves the old configuration before a change.
Why use it?
It helps explain why a source stopped collecting articles or repeatedly failed without changing live settings automatically.

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

source-healing scanned grade A with 1 finding 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 11d 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.

Source Healing

A guided workflow to find why a CTI source stopped collecting and fix it safely. You (Claude) are the diagnostic engine: you run probes, apply the playbook in references/playbook.md, and propose one concrete fix. A human approves every change.

Why this is a skill and not a background job

An automated version of this existed (Celery loop + headless LLM mutating live configs) and was removed because unattended config mutation was not production-safe. The valuable part — the probes and the symptom→fix playbook — is pure knowledge and lives on here. The safety comes from the delivery vehicle: an operator runs this, sees the diagnosis, and approves the fix. Keep that property. Do not add scheduling, auto-apply, or batch-without-confirm.

Operating rules (read before touching anything)

These exist because a source config is live production state and the fixes are inferred, not certain:

  • Propose, then confirm. Never write a change until the operator approves that specific change for that specific source.
  • Snapshot before any write. The pre-change row is the only way back.
  • One source at a time. "Heal all" iterates and re-confirms each source.
  • Never modify active, name, or identifier. Activation is an operator decision; identity changes break references. You only ever touch url, rss_url, and config.
  • Never invent URLs. Only use URLs you actually observed in probe output (RSS sample links, sitemap entries, redirect targets). A guessed post_url_regex or domain silently breaks collection.
  • Merge config, don't replace it. Read the existing config, change only the keys the fix requires, write the merged result back.
  • Bound the effort. At most 3 fix attempts per source. If the same class of failure survives 3 attempts, report it as a platform limitation rather than trying more permutations — some problems (bot protection, code bugs) cannot be fixed by config.
  • DB is runtime truth. Write fixes to the database. config/sources.yaml is only a new-build seed; it will drift and that is expected. Offer a YAML patch only as an optional final step, defaulting to skip.

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.

source-healing is a skill published in the GitHub repository dfirtnt/Huntable-CTI-Studio (11 stars, last pushed 3d ago), licensed MIT. It adds 155 tokens to every session and 2,415 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
