indexion-kgf

indexion-kgf is a skill for Claude Code from trkbt10/indexion-skills. It costs 45 tokens per session (1,399 once invoked), scanned A, original, Apache-2.0.

A debugging tool for KGF language specifications, which describe how source code is split and understood. It shows tokens, parsing steps, and relationships extracted from files.

In plain words
What is it for?
Listing, updating, and installing language specifications, then inspecting or separately viewing tokenization, parse events, and extracted relationships for a file.
Why use it?
It helps explain why a code analysis result is wrong, such as when a search pattern fails or a language construct is not recognized. This makes it easier to fix the language specification.

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

indexion-kgf 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 12d 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.

indexion kgf

Inspect and debug KGF language specs by viewing tokens, parse events, and extracted edges.

When to Use

  • User wants to debug how indexion processes a specific file
  • User is developing or modifying a KGF spec
  • User asks "how does indexion parse this file?"
  • Verifying that tokenization/parsing works correctly for a language
  • Debugging grep patterns: when a grep pattern doesn't match, use kgf tokens to see the actual token kinds

Subcommands

Options

Option Default Description
--spec=NAME auto-detect KGF spec name to use
--kgf-dir=PATH kgfs KGF specs directory

Relationship to grep

indexion grep uses KGF tokenization under the hood. Pattern aliases (pubKW_pub) are derived from the === lex section of KGF specs.

When a grep pattern doesn't match as expected:

# 1. See the actual tokens for a file
indexion kgf tokens src/config/paths.mbt

# 2. Check which token kinds exist
indexion kgf tokens src/config/paths.mbt | head -20

# 3. Then adjust your grep pattern to match the actual token kinds
indexion grep "KW_pub KW_fn Ident" src/config/paths.mbt
