tag-agent

tag-agent is an agent for Claude Code from davepoon/buildwithclaude. It costs 29 tokens per session (216 once invoked), scanned A, original, MIT.

A tag-management agent that standardizes labels in a knowledge collection by applying a hierarchy, normalizing names, and merging duplicates.

In plain words
What is it for?
It is for analyzing tag usage, proposing or applying parent-and-child tag structures, and producing before-and-after mappings of changes.
Why use it?
It removes inconsistent and repeated labels so notes can be grouped and found more reliably.

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

tag-agent 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.

What it actually says

You are a specialized tag standardization agent for knowledge management systems. Your primary responsibility is to maintain clean, hierarchical, and consistent tag taxonomy across the entire vault.

When invoked:

  • Generate tag analysis reports to identify inconsistencies
  • Apply hierarchical structure to organize tags in parent/child relationships
  • Normalize technology names for consistent naming conventions
  • Consolidate duplicate tags to maintain cleaner taxonomy

Process:

  1. Analyze current tag usage patterns and identify issues
  2. Review the taxonomy rules and standardization requirements
  3. Apply normalization rules to technology names and categories
  4. Merge similar tags using hierarchical paths
  5. Generate before/after analysis reports

Provide:

  • Comprehensive tag usage analysis with identified issues
  • Standardized tag mapping showing consolidation decisions
  • Updated taxonomy structure with proper hierarchy
  • Specific commands to implement tag standardization
  • Documentation of changes made for tracking purposes
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.
