scip-explore

scip-explore is a skill for Claude Code, Codex from PlunderStruck/scip-query. It costs 100 tokens per session (2,182 once invoked), scanned A, original, Apache-2.0.

A repository investigation guide for understanding how a system works from its starting input to its visible results. It follows code, runtime behavior, data changes, handoffs, failures, and recovery across files and symbols.

In plain words
What is it for?
It helps investigate systems end to end before explaining, planning, changing, or reviewing them, including tracing inputs, transformations, state changes, consumers, and failure paths.
Why use it?
It prevents explanations or changes based on only one part of a complex codebase. This is useful when behavior crosses multiple modules, processes, or state stores.

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

scip-explore 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/capture-evidence.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SCIP Explore

A repository system is the set of cooperating code, runtime mechanisms, and state resources whose coordinated behavior turns an initiating input into observable consequences. To understand one end to end is to reconstruct that behavior from its initiating boundary through every material decision, transformation, handoff, state change, result, and recovery path within the user's scope.

$scip-query is the sensing skill: it locates exact referents, projects typed relationships, reads implementation, and reports evidence strength and coverage. Load it before querying. This skill is the investigation skill: it decides which facts the answer must establish, integrates the observations, and decides when the system is understood well enough to answer. Do not duplicate the command manual here or treat either skill as a fixed command sequence.

Build the proof target

Before querying, restate the user's question as a checkable capability or decision. Then create a small private evidence ledger. An evidence ledger is a working record whose rows bind each material claim to the evidence needed to settle it. A material claim is a repository fact whose truth could change the requested explanation, decision, plan, or edit.

Start with three to seven rows, normally one for each distinct clause in the user's question. A row must be atomic enough that one status applies to every part of it. Split a row when different predicates, outcomes, fields, bounds, or failure paths require different evidence. Do not add rows merely because an unrelated implementation exposes more behavior.

Give each row one status:

  • unresolved: no sufficient evidence yet;
  • established: exact or adequately calibrated evidence supports the claim within stated coverage;
  • unsupported: a named provider or source limitation prevents the claim;
  • excluded: the claim cannot change the requested answer, with the reason recorded.

Derive rows from the question, not from a generic checklist. For an end-to-end behavior, test whether the answer depends on these five parts of the causal spine:

Files

What ships with it

5 files 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.

scip-explore is a skill published in the GitHub repository PlunderStruck/scip-query (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 100 tokens to every session and 2,182 once invoked, about $0.0005 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.
