Search Filter Check is an agent skill from MillenniumDawn/Millennium-Dawn.

Workflow steps

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

  1. No search_filters line.
  2. A filter that is not in the generic list, the Israel list, or the other-country
  3. FOCUS_FILTER_MILITARY. The filter is FOCUS_FILTER_MILITARY_LAWS.
  4. A custom filter with no generic alongside it. For Israel, check the generic against
  5. A country's custom filter in another country's file.
  6. FOCUS_FILTER_EXPENDITURE with no bankruptcy guard in ai_will_do. The guard must

What it can do on your machine

Read from SKILL.md and the folder at commit 5abce3e. 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

    Shell commands in SKILL.md call:

    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Search Filter Check loads about 473 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 180 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~473

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.

description
Validate search_filters on every focus in a file (or all focus files changed on the branch) against the approved filter list and the two-layer custom+generic convention. Use when asked to check or fix search filters on a focus tree.

Syntax: /search-filter-check [file_path]. Without a path, check every common/national_focus/*.txt file in git diff origin/main...HEAD --name-only.

Read .claude/docs/search-filters.md first. It is the filter list and the pairing reference.

Checks

For each focus = { ... } block, take its id and search_filters, then flag:

  1. No search_filters line.
  2. A filter that is not in the generic list, the Israel list, or the other-country list.
  3. FOCUS_FILTER_MILITARY. The filter is FOCUS_FILTER_MILITARY_LAWS.
  4. A custom filter with no generic alongside it. For Israel, check the generic against the ISRMILITARY and ISRECON mappings.
  5. A country's custom filter in another country's file.
  6. FOCUS_FILTER_EXPENDITURE with no bankruptcy guard in ai_will_do. The guard must not be in available.

End with N issues found across M focuses or All N focuses pass filter validation.

Fix when asked

Add missing generic filters, replace the legacy alias, and add the bankruptcy guard. Do not invent a custom filter. Flag those for human judgment.
