scip-plan

scip-plan is a skill for Codex from PlunderStruck/scip-query. It costs 52 tokens per session (1,470 once invoked), scanned A, original, Apache-2.0.

A planning guide that uses a repository's code relationships to produce a short, evidence-based implementation plan. It traces symbols, behavior, system boundaries, and downstream users of code.

In plain words
What is it for?
It helps plan features, bug fixes, refactors, migrations, and retirements by locating relevant code, understanding behavior, checking architecture, and assessing the impact of edits.
Why use it?
It reduces the need to rediscover how a codebase works before making a non-trivial change. A monorepo, for example, is one repository containing multiple projects or packages, so tracing relationships can be difficult.

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-plan 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.

SCIP Plan

Write a plan that another coding agent can execute without rediscovering the relevant system.

Command and question manual

Command syntax Question it answers
scip-query search <text> Locate exact repository text, a runtime key, or a compiler symbol; use `scip-query search -- ` when the literal starts with a dash.
scip-query outline <file> Locate compiler-owned constructs in a known file.
scip-query entrypoints <text> Locate an external callable root when its entry surface is known.
scip-query evidence --symbol <symbol> --edge <family> --direction <direction> --depth <n> --max-edges <n> Project explicitly selected typed relationships from one exact root.
scip-query inspect --at <file:line> --view behavior Read connected behavior for a named implementation gap.
scip-query code <selector> Read exact source only when syntax itself can change the decision.
scip-query diff-impact Map changed symbols and downstream consumers after an edit.
scip-query architecture Validate declared structural boundaries.
scip-query health --full Run configured cleanup and quality detectors.

These commands are controls, not a checklist. Use every capability needed by the task, but make each query answer a distinct question. There is no required sequence or query limit. Run a command's --help when you need a flag not shown in its template.

Choose a relationship deliberately

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-plan is a skill published in the GitHub repository PlunderStruck/scip-query (6 stars, last pushed today), licensed Apache-2.0. It adds 52 tokens to every session and 1,470 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 2026-08-31.
