What it does

Breach Notification Triage is an agent skill from ahmadvh/octochains. Determines whether a security incident involves personal data, triggers regulatory breach-notification obligations (e.g. GDPR Art. 33/34), and what notification timelines apply.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Legal & Compliance, covering Privacy and GDPR and Security operations. The repository describes itself as: A lightweight Python framework for parallel, isolated, collaborative AI reasoning.

When your agent uses it

  • Regulatory breach-notification obligations (e.g
  • Tasks that involve Privacy and GDPR
  • Tasks that involve Security operations

Example prompts

  • “Use the breach-notification-triage skill to determine whether a security incident involves personal data, triggers regulatory breach-notification…”
  • “/breach-notification-triage”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Data Classification: From the evidence, separate affected personal data (anything that identifies or relates to a natural person — names…
  2. Breach Determination: Decide whether the incident is a personal-data breach — a breach of security leading to the unlawful destruction…
  3. Authority Notification (GDPR Art. 33): If a personal-data breach is likely, assess the duty to notify the supervisory authority without…
  4. Individual Notification (GDPR Art. 34): Determine whether the breach is likely to result in a high risk to individuals, which additionally…
  5. Timeline & Obligations Summary: State each triggered obligation, its deadline, and its recipient (supervisory authority vs. affected…

What it can do on your machine

Read from SKILL.md and the folder at commit 3512a57. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Breach Notification Triage loads about 861 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 421 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~861

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 421 words (~861 tokens).

“Assess a security incident purely through a regulatory breach-notification lens: decide whether personal data was affected, which notification obligations are triggered, and the deadlines that apply.”
