What does this PR do?

Adds a shared Graphify knowledge graph (graphify-out/) to the repo so the team can navigate the codebase by querying the graph instead of running grep/find across source files. Includes IDE integrations for Claude Code (.claude/settings.json with enforcement hooks), Cursor (.cursor/rules/), and OpenCode (.opencode/plugins/), plus a new AGENTS.md section and CONTRIBUTING.md onboarding guide.

Querying the graph via /graphify query "..." costs a fraction of the tokens compared to raw file searches — relevant for AI agent sessions where codebase exploration is the main token driver.

📝 Walkthrough

Walkthrough

The change adds a Graphify report and repository navigation guidance. It also adds tool integrations that prompt code exploration tools to use Graphify when its graph is available, and ignore rules for generated Graphify output.

Changes

Graphify navigation

Layer / File(s) Summary
Graph report and generated output handling
graphify-out/GRAPH_REPORT.md, .gitignore
Adds a report with graph statistics, community summaries, connections, and suggested questions. Adds ignore rules for Graphify cache and generated files.
Repository navigation instructions
AGENTS.md, CONTRIBUTING.md
Adds Graphify usage guidance for repository questions, code changes, and contributor setup.
Code exploration tool prompts
.claude/settings.json, .cursor/rules/graphify.mdc, .opencode/opencode.json, .opencode/plugins/graphify.js
Adds Graphify prompts and tool hooks for Claude, Cursor, and OpenCode. The hooks check for the graph file before prompting.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Other

Merge Risk: 🔵 Low · up to 4f882

The navigation additions have bounded developer-workflow issues: fresh environments lack the documented CLI, and OpenCode executes a placeholder query instead of printing it. Both have localized fixes; no production behavior is changed.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 4f882

A navigation reminder can inadvertently run an additional command in a contributor’s shell. Its activation is limited, and no privilege escalation is established, but the additional command’s authorization remains unverified.

Retained concerns

  • Low · security · inferred: The new OpenCode reminder promotes guidance into executable shell behavior. JavaScript consumes the backtick escapes, leaving command substitution that would invoke graphify query before the requested command. Whether authorization covers this additional execution is unresolved.
Security review details

Security Blast Radius

  • inferred — The supported exposure is an additional subprocess within an eligible local Bash-tool execution. The supplied evidence does not establish a network entrypoint, tenant exposure, production-service propagation, or increased operating-system privileges.

Security Findings and Attack Paths

  • inferred — If the rewritten string reaches Bash, command substitution attempts the fixed graphify query before the original operation. This establishes unintended executable behavior, not arbitrary attacker-controlled command injection or a verified authorization bypass.

Trust Boundaries and Controls

  • observed — Graph existence, Bash-tool selection, and the per-instance latch restrict activation. The fixed reminder does not interpolate graph data or additional caller-controlled fields. No framework permission check is visible in this plugin, so authorization sequencing remains a coverage gap rather than a proven bypass.

Resilience and Maintainability Implications

  • inferred — The latch limits repeated injection within one instance but is not a security authorization or successful-execution record. Cancellation and subsequent retries can therefore have different reminder behavior without any supplied recovery contract.

Hardening Proposals

  • proposed — Prefer a documented non-executable context channel for navigation guidance, leaving the requested shell command unchanged. If command rewriting remains necessary, establish that authorization evaluates the final rewritten command.

Quote the reminder without shell command substitution.

When the graph exists, the first eligible Bash call can execute graphify query "<question>" as command substitution. Its output replaces the example in the reminder, while the original Bash command still runs. Use printf with a shell single-quoted reminder.

This repository ships a pre-built knowledge graph (`graphify-out/`) to help navigate the codebase without expensive file searches. After cloning or pulling, run once to anchor the graph to your local paths:

```bash
graphify update .

Install Graphify before the first setup command.

On a fresh development environment, this procedure fails with graphify: command not found. Add the Graphify installation step before graphify update .. Specify the official package name, graphifyy, to avoid similarly named packages. The upstream installation instructions use uv tool install graphifyy or pipx install graphifyy. (github.com)
