# Graphifyy vs GrepAI — evaluation protocol (GURU-5070)

Goal: real, comparable data on whether **Graphifyy** beats the incumbent **GrepAI** for
Mike's day-to-day in ClaudeTools, enough to make an adopt / skip / adopt-narrowly call.
Decision hinges on token efficiency + retrieval quality, weighed against maintenance cost.

## Tools under test
- **GrepAI** — `D:\claudetools\grepai.exe mcp-serve`, exposed as `mcp__grepai__*` (semantic
  search + RPG graph: explore / trace_callers / trace_callees / trace_graph). Repo-wide index
  already built (`.grepai/`). Enabled per-machine via `enabledMcpjsonServers:["grepai"]` in
  `.claude/settings.local.json`.
- **Graphifyy** — `pip install graphifyy && graphify install`. Local graph (NetworkX +
  tree-sitter + Leiden). CLI/skill: `graphify <path> [--mode deep|--update]`,
  `graphify query "q"`, `graphify path "A" "B"`, `graphify explain "C"`. Docs/PDF/images
  ingested via Claude API (token cost); code parsed locally.

## Arms (run in separate sessions; MCP toggles need a restart)
- **A — GrepAI** (baseline / "before"): grepai ON, Graphifyy not used. Run FIRST, this session.
- **B — Graphifyy** ("after"): Graphifyy ON, grepai DISABLED (removed from
  `enabledMcpjsonServers`). New session.
- **C — Control** (optional): both off; only `grep`/`glob`/`Read`. Shows whether either graph
  tool beats plain search.

Same model for all arms. Each query answered in a FRESH sub-agent constrained to that arm's
tools, to avoid cross-arm contamination. Scoring done against the rubric, blind to arm where
feasible.

## Fixed test corpus (both tools index the SAME slice)
To keep it fair and bounded (not the whole repo + node_modules):
- Code: `projects/msp-tools/guru-rmm/` (Rust server + agent + React dashboard)
- Docs: `wiki/`, `projects/msp-pricing/`, `clients/kittle/`, `clients/dataforth/`
- PDF: `projects/msp-pricing/marketing/The Arizona Business Owner's Guide to Choosing an MSP - Arizona Computer Guru.pdf`

Note asymmetry: GrepAI's existing index is repo-wide (slight recall edge, more noise);
Graphifyy indexes exactly this slice. All test queries are answerable from the slice.

## Metrics (per query x arm)
| Metric | How captured |
|---|---|
| `ctx_tokens` | chars of retrieved context the agent consumed / 4 (consistent approx) |
| `tool_calls` | number of retrieval round-trips to reach the answer |
| `latency_s` | wall-clock for the query |
| `score` | 0 = wrong/missing, 1 = partial, 2 = complete & correct (vs rubric) |

One-time / maintenance (measured once per tool):
- `index_build_s` — full index of the test corpus (code-only, then code+docs)
- `reindex_s` — incremental update after touching ONE file
- `ingest_api_tokens` — Graphifyy's Claude-API tokens to ingest docs/PDF/images
  (GrepAI: note its embedding model/cost; LLM-ingestion ≈ 0)

## Test set (10 queries; code-heavy + docs-heavy, since docs is Graphifyy's claimed edge)
Each has a rubric = key facts a correct answer MUST contain.

CODE
- C1: "In GuruRMM, how does the server avoid false-failing commands that were delivered but not
  acked? Name the mechanism + migrations." Rubric: agent CommandAck on receipt + dedup; reaper
  RE-DELIVERS un-acked instead of false-failing; migrations 058 acked_at / 059 delivery_attempts.
- C2: "Trace where un-acked command re-delivery is handled in the RMM server and what calls it."
  Rubric: the reaper fn + its caller path. (grepai trace_callers vs graphify path)
- C3: "Where is GuruRMM agent self-update with rollback implemented and what guards it?"
  Rubric: agent `updater/mod.rs` + watchdog.
- C4: "What does GuruConnect SPEC-018 propose?" Rubric: session broker / capture worker as SYSTEM.

DOCS / KNOWLEDGE (Graphifyy's claimed strength)
- D1: "GPS pricing structure (tiers + prices)?" Rubric: Basic $19 / Pro $26 / Advanced $39 per
  endpoint; support plans Essential/Standard/Premium/Priority.
- D2: "Summarize the Kittle BEC/ACH-fraud incident and root cause." Rubric: Ken+marco+Accounting
  compromised; fraudulent bank-change to City of Tucson + Marana ($130K+ prevented); IC3 filed;
  root cause = April credential theft + incomplete remediation (password never reset, ~2mo).
- D3: "Which ACG clients had M365 breach/credential incidents in 2026 and each root cause?"
  Rubric (relationship query): Kittle (BEC), Dataforth (2026-03-27 phishing -> MFA), mvaninc
  (unauthorized sign-in OKC). Partial credit per client.
- D4: "List the 7 red flags of a bad MSP from the Buyers Guide." Rubric: the 7 from
  MSP-Buyers-Guide-Content.md (unlimited-support, high-pressure sales, offshore-only, no
  proactive monitoring, long lock-ins, one-size packages, no local presence). PDF/doc ingestion.
- D5: "Canonical Kittle article path + what it superseded?" Rubric: clients/kittle.md canonical;
  kittle-design.md superseded 2026-06-09.

MIXED (code + docs)
- M1: "How do new GuruRMM builds get promoted from beta to stable?" Rubric: builds tag beta;
  promote via POST /api/updates/rollouts/:version/promote; build-server.sh auto-deploys.

## Procedure
1. (Arm A, now) For each query, spawn a sub-agent: tools = grepai + Read only; instruct it to
   use ONLY grepai for retrieval, answer, and report (answer, total retrieved chars, # grepai
   calls, elapsed). Log to results.csv with arm=A.
2. Score each answer 0/1/2 vs rubric.
3. Disable GrepAI (below), install + index Graphifyy, measure one-time costs.
4. (Arm B, new session) Same queries, sub-agent tools = Bash(graphify) + Read; use ONLY
   graphify for retrieval. Log arm=B. Score.
5. (Arm C, optional) grep/glob/Read only. Log arm=C.
6. Analyze: per-metric medians by arm; weight ctx_tokens + score (the day-to-day levers);
   factor in index/maintenance cost and the doc-vs-code split.

## Reversible environment changes (per-machine only)
Disable GrepAI (edit `.claude/settings.local.json`, remove "grepai" from
`enabledMcpjsonServers`; restart session). Re-enable = add it back. **Do NOT edit `.mcp.json`**
(shared/fleet). Install Graphifyy: `py -m pip install graphifyy && graphify install`. Uninstall
= `py -m pip uninstall graphifyy` + remove its skill. Snapshot of `settings.local.json` kept at
`projects/graphifyy-eval/settings.local.json.bak` before any edit.

## Open setup unknowns to resolve at install
- Which API key/env var Graphifyy uses for doc/PDF/image ingestion (README didn't say; it bills
  as "a Claude Code skill"). Confirm before indexing docs so ingest cost is attributable.
- Whether `graphify query` itself spends LLM tokens to answer (vs returning raw graph context) —
  affects per-query cost comparison; measure.
