kb-codeindex

kb-codeindex is a skill for Claude Code from SteveGJones/ai-first-sdlc-practices. It costs 62 tokens per session (641 once invoked), scanned A, original, MIT.

A project code-index builder that turns source-code annotations and imports into searchable Markdown indexes. An index is a structured map of where code is implemented and how modules depend on one another.

In plain words
What is it for?
Use it after changing `# implements:` annotations or imports to refresh the code index and dependency-edge files across supported programming languages.
Why use it?
It makes a large codebase easier to research and shows unresolved references as warnings instead of silently losing them.

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

kb-codeindex 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 7d 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.

Skill: kb-codeindex

Use this skill to build or refresh the project's code index. The output is structurally a KB shelf-index, queryable by the research-librarian agent like the regular library files. Run after adding/changing # implements: annotations or modifying import structure.

Inputs

  • (no arguments — operates on the whole project)

Steps

  1. Load the project root. Detect from .git/.

  2. Walk source files. Glob **/*.{py,js,ts,go,rs,java} excluding standard ignored paths (.venv/, node_modules/, .git/, etc.).

  3. Parse annotations. Use parse_code_annotations to extract every # implements: line.

  4. Verify cited IDs. For each citation, look it up in library/_ids.md. Report unresolved citations as warnings (not errors — annotation_format_integrity blocks at pre-push).

  5. Render the index. Use render_code_index to produce shelf-index-shaped markdown.

  6. Write to library/_code-index.md. If the file already exists, compare byte-for-byte; only write if different.

  7. Extract dependency edges. For each language detected in the project paths, invoke the registered DependencyExtractor adapter:

    • Python paths → PythonAstExtractor (uses ast.parse for precise cross-module import resolution)
    • All other paths → GenericRegexExtractor (regex-based; configured per language via make_swift_extractor() or equivalent)

    Accumulate all returned ImportEdge objects across languages. Resolve each edge against the Decomposition module paths so edges carry qualified module IDs (e.g. P1.SP1.M1 → P1.SP1.M2). Edges that cannot be resolved to a known module are silently dropped (same policy as unresolved annotation citations).

  8. Write to library/_dependency-edges.md. Use render_dependency_edges(edges, library_handle=<library-handle>) to produce the artefact. If the file already exists, compare byte-for-byte; only write if different. The file is consumed by visibility_rule_enforcement during decomposition validation.

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.

kb-codeindex is a skill published in the GitHub repository SteveGJones/ai-first-sdlc-practices (41 stars, last pushed 28d ago), licensed MIT. It adds 62 tokens to every session and 641 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
