claude-vibe-squad: Skill for Claude Code

.agents/skills/cross-file-relationship-synthesis/SKILL.md

cross-file-relationship-synthesis is a skill for Claude Code, Codex from mtarcure/claude-vibe-squad. It costs 82 tokens per session (511 once invoked), scanned A, original, MIT.

A guide for combining evidence from several repository files into one map of how code and data are connected. It records calls, imports, configuration links, and producer-consumer relationships with line references.

In plain words
What is it for?
Use it to trace dependencies across files, estimate the impact of a change, find orphaned components, and support conclusions with repository traversal evidence.
Why use it?
Reading files separately can hide how a change travels through the project. The map helps reveal affected code, unused parts, and points where behavior enters or leaves a system.

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

cross-file-relationship-synthesis 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.

What it actually says

Cross-File Relationship Synthesis

Turn a set of independently-read files into an explicit relationship map, so conclusions rest on traced edges rather than on the impression that the files are related.

Steps

  1. List the files in scope and give each a one-line role. A file whose role you cannot state in one line has not been understood well enough to relate to others.
  2. Name the edge kinds you will trace before tracing them — calls, imports, writes-then-reads, schema producer/consumer, config-to-consumer, generator-to-generated. Untyped "related to" edges hide the actual dependency.
  3. Trace each edge in the direction data or control actually flows, and record the file and line at both ends. An edge without two anchors is a hypothesis.
  4. Distinguish edges you observed from edges you inferred from naming. Matching names are a lead to verify, never an edge.
  5. Look specifically for the edges that contradict the obvious structure: the secondary writer, the path that bypasses the abstraction, the consumer nobody registered. These decide correctness more often than the primary path does.
  6. Identify the cut points — files whose change propagates furthest — and state the blast radius of each as a concrete list of affected files.
  7. Check the map for orphans and dead ends, and resolve each: either an edge is missing from the map, or the file genuinely is unreachable. Never leave the ambiguity unexplained.
  8. State the conclusion as a traversal over the map, so a reader can follow the same path and reach the same result.

Acceptance

  • Every file in scope has a stated one-line role.
  • Every edge is typed, directed, and anchored at both ends with file and line.
  • Observed edges and name-inferred edges are visibly separated.
  • Cut points are named with an explicit blast-radius file list.
  • Orphans and dead ends are each resolved as missing-edge or genuinely-unreachable.
  • The final claim is expressed as a walk over recorded edges, not as a summary impression.
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.
