graphify-agents

name	graphify-agents
description	Use a graphify knowledge graph to give agents low-token codebase context — query the graph instead of reading raw files during research, decomposition, and impact analysis. Use when wiring graphify into an agent-loop, an Explore/research subagent, or an MCP-enabled agent, or when deciding when a graph query beats grepping and reading files.

Graphify for Agents

Reading raw files into context is the dominant token cost of codebase-understanding work. Graphify builds a knowledge graph once (graphify-out/graph.json) and answers structural questions by traversing it — returning the relevant nodes and edges instead of whole files. This skill covers using that graph to make agent workflows cheaper and more targeted.

The project's published benchmark reports "71.5x fewer tokens per query vs reading raw files" on a mixed corpus, with smaller gains (≈5.4x on a 4-file corpus, ≈1x on a 6-file library) — the advantage scales with corpus size. Measure a specific repo with graphify benchmark before quoting a number; small repos see little benefit, so reserve the graph for large corpora.

When to Use This Skill

Activate when:

• Giving a research or Explore subagent codebase context without reading every file
• Adding a graph-build + graph-query step to a /core:agent-loop Phase 1 pre-flight
• Doing impact analysis ("what breaks if I change X") before decomposing an epic
• Exposing the graph to an agent through the graphify MCP server
• Deciding between a graph query and grep+read for a given question

The Core Pattern: Query, Don't Read

Question shape	Without graphify	With graphify
"How does auth connect to the request pipeline?"	Grep, open 6–10 files, read each	graphify query "how does auth connect to the request pipeline?" → relevant nodes + edges
"What is SwinTransformer and what touches it?"	Read the class + every caller	graphify explain "SwinTransformer"
"What breaks if I change add?"	Trace callers by hand	graphify affected "add"
"How do these two modules connect?"	Read both, infer	graphify path "DigestAuth" "Response"

query returns within a token budget (--budget, default 2000), so an agent gets a bounded, relevant slice rather than unbounded file contents.

Integration with /core:agent-loop

Graphify slots into the loop's existing phases without replacing them. Load /core:agent-loop for the phase model.

Phase 1 (Pre-flight / research). Before decomposition, build or refresh the graph, then have the research/Explore subagent query it instead of fanning out file reads:

mise run graphify:update      # AST-only refresh, no API key needed
graphify query "where is <epic-area> implemented and what does it depend on?"

Feed the query result into the Team Leader's decomposition. The graph names the real files and symbols to reference in worker prompts — which the agent-loop prompt template already requires ("reference existing code and functions to reuse").

Phase 2 (Working). Give each worker the path/explain output for its slice instead of pre-reading files into the prompt. Workers still read the specific files they edit.

Impact analysis before slicing. graphify affected "<symbol>" (needs a full clustered build) surfaces the blast radius of a change, which informs dependency edges between bees issues.

Keeping the Graph Fresh

A stale graph misleads agents the way stale docs do. Keep it current:

graphify hook install    # rebuild on post-commit / post-checkout
graphify watch .         # rebuild live during a session

The agent that relies on the graph confirms freshness — graphify check-update . reports whether a semantic re-extraction is pending. Treat graph claims like any other: an agent verifies a graph answer against the actual file before acting on it (anti-fabrication).

Exposing the Graph via MCP

graphify . --mcp starts an MCP stdio server (the [mcp] extra / graphify-mcp console script). An MCP-enabled agent then calls graphify tools directly rather than shelling out. See /claude-code:claude-agents (sibling plugin, install claude-code@vinnie357; MCP-enabled agent pattern) for declaring the server in an agent's tool set.

Registering graphify with Claude Code

graphify claude install writes a graphify section to CLAUDE.md and a PreToolUse hook so a Claude Code session reaches for the graph automatically. This is graphify's own integration; this marketplace's graphify/graphify-agents skills are the alternative, progressive-disclosure path that does not modify CLAUDE.md.

When NOT to Use the Graph

• Small repos (the benchmark shows ≈1x on a 6-file library) — grep+read is simpler.
• Questions about the exact current contents of one known file — read it.
• Anything where the graph has not been rebuilt since the relevant code changed — refresh first or read directly.

Anti-Fabrication Requirements

• Run graphify benchmark (or cite the project's published figures as such) before stating a token-savings number — never present a benchmark figure as independent measurement.
• Verify a graph answer against the actual source file before an agent acts on it.
• Confirm graph freshness (graphify check-update) before trusting a query in a long session.
• State which commands require a full clustered build vs a raw AST extraction (affected and community labels need clustering).
