Build Knowledge Graph

Self-Evolving Skill: This skill improves through use. If a backend command drifts, a flag changes, or a new failure mode appears — fix this file (and references/backends.md) immediately, don't defer. Only update for real, reproducible issues.

Run the graphify engine on a target folder and surface what it found.

Prerequisite: graphify CLI on PATH. If missing, invoke graphify-tools:setup first.

Complement, not replacement: for symbol-level code questions (callers/callees/impact) use the codegraph MCP tools — they are sub-ms and deterministic. Reach for graphify when the corpus is mixed (code + docs + papers + images) or the question is conceptual ("what connects X to Y across these files?").

Steps

1. Scope the target

Default to the current repo, but ASK before running on anything huge — LLM extraction of docs/images costs tokens and time. Scoping heuristics:

# Size check first
scc --no-complexity <target> 2>/dev/null | tail -3
find <target> -name '*.pdf' -o -name '*.png' -o -name '*.jpg' | wc -l

• < ~100 files: run directly
• Larger: propose a subfolder (e.g. docs/, one plugin dir) or --update incremental mode
• 1000s of files with many same-named files (e.g. a marketplace of SKILL.mds): cross-chunk node-ID collisions silently drop the second same-named node. Extract per-subfolder then graphify merge-graphs, rather than one whole-repo shot.

2. Build

Pick a backend and set its env — full copy-paste blocks for all three live in ../../references/backends.md (the routing SSoT). Quick guide:

Backend	When	One-liner
gemini-2.5-flash	large / bulk runs (safe default, no ban-risk)	graphify extract <target> --backend gemini --model gemini-2.5-flash
fleet Opus 4.8	interactive / smaller graphs, best quality ("our LLM")	--backend openai --model claude-opus-4-8 + GRAPHIFY_LLM_TEMPERATURE=omit
MiniMax-M3	a few dense files, latency OK	--backend openai --model MiniMax-M3

Always unset HTTPS_PROXY HTTP_PROXY https_proxy http_proxy first — the ccmax-claude bearer-pin proxy 502s external hosts. The claude backend is BLOCKED (doorward 426); use the fleet openai door instead. See backends.md for keys, base URLs, and the mandatory GRAPHIFY_LLM_TEMPERATURE=omit for Opus.

Two-step headless flow (any backend): graphify extract <target> … then graphify cluster-only <target> … (regenerates GRAPH_REPORT.md + names communities). The plain graphify <target> one-shot also works once a backend's env is set. Cost prints after every run — relay it.

Useful flags (combinable):

Flag	Effect
--mode deep	More aggressive INFERRED edge extraction (slower, more edges)
--update	Re-extract only changed files (SHA256 cache), merge into existing graph
--wiki	Also emit agent-crawlable wiki (index.md + article per community)
--svg / --graphml	Static exports (Gephi, yEd)

Output lands in <target>/graphify-out/:

graphify-out/
├── graph.html       interactive graph (click, search, filter by community)
├── obsidian/        openable as an Obsidian vault
├── wiki/            (with --wiki) agent-navigable markdown wiki
├── GRAPH_REPORT.md  god nodes, surprising connections, suggested questions
├── graph.json       persistent graph — query later without re-reading files
└── cache/           SHA256 file cache for incremental --update runs

3. Report

Read graphify-out/GRAPH_REPORT.md and summarize for the operator:

1. God nodes — highest-degree concepts everything routes through
2. Surprising connections — with the plain-English "why" (code↔doc edges rank highest)
3. Suggested questions — what the graph is uniquely positioned to answer
4. Token benchmark — the printed reduction factor vs reading raw files

Remind the operator every edge is tagged EXTRACTED / INFERRED / AMBIGUOUS — trust extracted, verify inferred.

4. Ingest external sources (optional)

graphify add https://arxiv.org/abs/<id>     # paper → saved + merged into graph
graphify add https://x.com/<user>/status/…  # tweet

Housekeeping

Add graphify-out/ to .gitignore unless the operator explicitly wants the graph committed (graph.json can be large; cache/ is machine-local).

Post-Execution Reflection

After this skill completes, reflect before closing the task:

0. Locate yourself. — Find this SKILL.md's canonical path before editing.
1. What failed? — Fix the instruction that caused it.
2. What worked better than expected? — Promote to recommended practice.
3. What drifted? — Fix any script, reference, or dependency (esp. references/backends.md) that no longer matches reality.
4. Log it. — Add a dated note to the plugin CLAUDE.md provenance with trigger, fix, and evidence.

Do NOT defer. The next invocation inherits whatever you leave behind.
