call-graph-analysis

call-graph-analysis is a skill for Claude Code from openshift-eng/ai-helpers. It costs 21 tokens per session (3,268 once invoked), scanned B, original, Apache-2.0.

A call-graph analysis workflow that traces which functions can reach a vulnerable function during program execution. A call graph is a map of possible calls between functions.

In plain words
What is it for?
Use it to confirm CVE impact in Go code, produce execution-path evidence for audits, and optionally create visual graphs with Graphviz.
Why use it?
It provides stronger evidence about whether a vulnerability is actually reachable when simpler dependency checks are inconclusive.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is # TARGET_PKG is the specific main package (e.g. ./cmd/controller, .).

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 B, and why

call-graph-analysis scanned grade B with 1 finding 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 23d 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.

Call Graph Reachability Analysis

Provides highest-confidence vulnerability assessment by proving whether vulnerable functions can actually be reached during program execution.

When to Use This Skill

Use this skill when:

  • You need definitive proof that a vulnerable function is or isn't reachable
  • Medium/high confidence analysis shows possible vulnerability but needs confirmation
  • Generating evidence for security compliance or audit requirements
  • govulncheck is unavailable or didn't find the CVE
  • You need visual proof of execution paths for stakeholders

Prerequisites

Required Tools

  • callgraph: go install golang.org/x/tools/cmd/callgraph@latest
  • digraph: go install golang.org/x/tools/cmd/digraph@latest
  • Go workspace with go.mod file

Optional Tools

  • graphviz (for visualization): brew install graphviz (macOS) or sudo apt-get install graphviz (Linux)
  • sfdp or dot command (part of graphviz)

Input Requirements

  • CVE vulnerable function signature (e.g., <package-path>.<function-name>)
  • Package path from CVE analysis
  • Workspace path to analyze
  • Algorithm preference (optional, default: vta) — passed via --algo from parent command
  • CVE_ID — used to construct the output directory
  • OUT_DIR (optional, default: ${AI_HELPERS_WORKSPACE:-.}/.work/compliance/analyze-cve/${CVE_ID}) — where artifacts are written; same workspace base as Phase 0.7's REPOS_BASE

Critical Rules

  1. Always use timeout -k 10 — plain timeout sends SIGTERM but callgraph can ignore it when stuck in SSA construction or type resolution. -k 10 sends SIGKILL after 10s grace, guaranteeing termination.
  2. Never run callgraph on ./... for repos with more than ~50 packages. Target specific main packages (e.g. ./cmd/controller, ./main.go) and let the tool pull in transitive deps automatically.
  3. Always redirect output to a file (> file 2>&1). Never pipe callgraph output to another command — if the reader closes, callgraph can hang on SIGPIPE.

call-graph-analysis is a skill published in the GitHub repository openshift-eng/ai-helpers (121 stars, last pushed today), licensed Apache-2.0. It adds 21 tokens to every session and 3,268 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
