klimkit-code-explorer

A read-only method for understanding an unfamiliar codebase before editing it. It traces how code runs across files, symbols, callers, tests, documentation, and configuration.

In plain words
What is it for?
Use it to find entry points, follow execution paths, inspect related tests, identify contradictions, and decide which files are most likely to need changes.
Why use it?
It reduces the chance of changing the wrong part of a system or missing an existing convention. It also separates confirmed behavior from assumptions.

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

klimkit-code-explorer 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 2d 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

Klimkit Code Explorer

Use this for read-only discovery before edits. Report what the code does, where it does it, and which files or symbols matter.

Workflow

  1. State the question being explored.
  2. Search first with rg or rg --files.
  3. Read entry points, callers, tests, docs, and configuration that shape the behavior.
  4. Trace the execution path with concrete file and symbol references.
  5. Surface contradictions or competing patterns instead of blending them.
  6. Identify the smallest likely change surface and the tests or checks that should cover it.
  7. Stop before editing. If implementation is requested next, hand the findings to klimkit-implement or the narrow method skill.

Report Shape

  • Question: one sentence.
  • Execution path: files and symbols in order.
  • Relevant tests: existing coverage and gaps.
  • Risks or contradictions: only concrete ones.
  • Likely change surface: files to inspect or edit next.

Avoid speculative fixes unless the user explicitly asks for recommendations.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

klimkit-code-explorer is a skill published in the GitHub repository klimentij/klimkit (7 stars, last pushed 22d ago), licensed MIT. It adds 49 tokens to every session and 271 once invoked, about $0.0002 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 2026-08-31.
