docs: agent development framework, GitHub templates, eval refactor

[jreakin]

Summary

Documentation, templates, and eval tooling. Zero runtime impact. Split from #303 (PR 6 of 6). Depends on #486.

Why this matters

GitNexus is increasingly contributed to by AI agents (Claude Code, Cursor, GitHub Copilot) alongside human developers. Without structured guidance, agents make well-intentioned but unsafe changes — renaming symbols with find-and-replace instead of the graph-aware rename tool, skipping impact analysis before edits, committing without running detect_changes, or accidentally deleting embeddings by running analyze without --embeddings.

This PR introduces a layered documentation framework that gives both human and AI contributors the same guardrails:

1. What to do before editing — run impact analysis, check blast radius, understand risk levels
2. What never to do — no secrets, no find-and-replace renames, no commits without change detection
3. How to recover — copy-paste runbook commands for every common failure mode
4. How to contribute — PR template enforces test verification, conventional commits, area-touched checkboxes

The framework is self-referential: the project is indexed by GitNexus itself, so agents reading AGENTS.md are instructed to use GitNexus MCP tools to safely navigate the codebase they're modifying. This makes AI-assisted contributions reproducible and auditable.

Agent Framework

These documents form a layered system — policy on top, operations in the middle, architecture at the base:

Policy layer — rules and safety gates:

• AGENTS.md — Canonical agent instructions. Mandatory impact analysis before edits (gitnexus_impact), change detection before commits (gitnexus_detect_changes), scope boundaries (what agents can read/write/execute vs. what's off-limits). Includes GitNexus MCP tool quick reference and impact risk levels (d=1 WILL BREAK → d=3 MAY NEED TESTING). Recurring failure patterns ("Signs") with fixes.
• CLAUDE.md — Claude Code-specific deltas. PreToolUse hooks for hard gates (e.g., tests before git_commit). Execution sequence discipline for long sessions. Defers all MCP guidance to AGENTS.md as single source of truth.
• GUARDRAILS.md — Safety boundaries for humans and AI. Five non-negotiables: no secrets, use rename tool, impact analysis, detect_changes, preserve embeddings. Escalation scenarios (HIGH/CRITICAL risk, CI/release changes, data loss uncertainty). Publishing and supply chain rules.

Operations layer — what to run and when:

• TESTING.md — Test structure, commands, and targets for both packages (gitnexus CLI: vitest; gitnexus-web: vitest + Playwright E2E). Categories: unit, integration, eval-style golden sets, E2E. Known issues (LadybugDB locking in containers).
• RUNBOOK.md — Copy-paste operations: index a repo, generate embeddings, troubleshoot MCP (no repos → run analyze; wrong repo → use list_repos + repo param), clean slate, CI failure repro, memory/locking issues.

Architecture layer — system context:

• ARCHITECTURE.md — Monorepo layout (gitnexus CLI/MCP, gitnexus-web React/Vite, plugin packages, eval harness). End-to-end data flow: Tree-sitter parsing → LadybugDB persistence → MCP tools/resources. Where-to-change-what map for common modifications.
• llms.txt — Minimal pointer document listing key docs and directories for LLM context seeding.

Editor Integration

• .cursor/index.mdc — Always-on Cursor Cloud rules pointing to AGENTS.md for canonical instructions.
• .cursor/rules/100-monorepo.mdc — Glob-scoped build/test quick reference per package. Known issues (native build tools, LadybugDB locking).
• .cursorrules — Legacy deprecation stub pointing to .cursor/index.mdc.

GitHub Templates

• PR template — Structured sections: summary, motivation, areas touched (checkboxes for CLI, web, CI, docs, eval), scope/constraints, implementation notes, testing/verification (with test command checkboxes), risk/rollout, and checklist (PR body, AGENTS.md changelog, no secrets, validation).
• Bug report form — Area dropdown (CLI/core, web UI, CI, docs, other), structured fields for summary, context, expected/actual behavior, reproduction steps, environment, logs/screenshots.
• Feature request form — Area dropdown, problem/opportunity, proposed solution, alternatives, acceptance criteria, contributor willingness checkbox.
• config.yml — Blank issues enabled for edge cases outside the templates.

Eval Harness

• tool_registry.py — Centralized tool script specs and metric keys (was scattered across multiple files).
• constants.py — Shared constants for eval/bridge timeouts and defaults.
• utils/errors.py — Debug-gated exception sanitization using traceback.format_exception (not format_exc) for reliable traceback capture. log_safe_exception helper for consistent error logging without stack trace leaks.
• bridge/mcp_bridge.py — Centralized MCP timeout constants, improved subprocess stream closing, refactored response reading.
• analysis/analyze_results.py — Longest-suffix-first run-ID parsing, flexible mode ordering, shared metric keys.
• Property-based tests via Hypothesis: run-ID parsing, tool script rendering, error sanitization edge cases.

Test plan

• All docs render correctly on GitHub
• Eval tests pass locally
• PR template renders with correct checkboxes
• Issue forms show area dropdowns
• .cursor/index.mdc loads in Cursor Cloud

AI Context Engineering Review — Cursor Setup & Token Optimization

Tasks:

• Understand the request
• Read AGENTS.md, CLAUDE.md, GUARDRAILS.md
• Read .cursor/index.mdc, .cursor/rules/100-monorepo.mdc, .cursorrules
• Read llms.txt, ARCHITECTURE.md, CONTRIBUTING.md
• Analyze token efficiency of current setup
• Write detailed review

Direction Assessment: Mostly Right, But Critical Token Waste Found

The layered architecture (policy → operations → architecture) is the correct mental model for multi-agent contexts. The decisions to use .cursor/index.mdc as a pointer, scope rules with globs, and deprecate .cursorrules all follow current best practices. However, there are two critical duplication bugs that waste a significant number of tokens per session, plus several structural improvements worth making.

---

🔴 Critical: gitnexus:start Block Is Loaded Twice Per Claude Code Session

CLAUDE.md lines 60–161 contain the full `` block — the same ~100-line GitNexus tool reference that also lives in AGENTS.md. CLAUDE.md is always loaded by Claude Code, so every session consumes this block plus any time AGENTS.md is read. Line 58 of CLAUDE.md even says:

"For all GitNexus MCP guidance…, use AGENTS.md as the single source of truth."

…and then immediately embeds the full block, contradicting itself.

Token cost: ~700 tokens per Claude Code session, every session, even for doc-only or eval work.

Fix: Replace lines 60–161 in CLAUDE.md with a single pointer:

GitNexus MCP rules are in the `` block in **AGENTS.md** — load that section when working with MCP tools or the graph index.

🔴 Critical: gitnexus:start Block Is Duplicated Inside AGENTS.md Itself

In AGENTS.md, the Reference Documentation bullet at line 51 embeds the entire gitnexus:start block inline as the value of a list item (lines 52–151), and then the same block appears again as a standalone section at lines 162–262. This means any agent that reads AGENTS.md linearly processes the block twice.

This is likely a markdown formatting artifact — the reference text tried to say "see the block below" but instead pasted the block as literal text. The reference bullet should read:

- **GitNexus:** skills under `.claude/skills/gitnexus/`; machine-oriented rules in the `gitnexus:start` … `gitnexus:end` block below.

---

🟡 High: .cursor/index.mdc Is Too Minimal for "Always On" Use

Current content (~13 lines) just says "go read AGENTS.md." With alwaysApply: true, Cursor injects this file's content into every request context — which means the 3 most critical rules (impact before edit, detect_changes before commit, never find-and-replace rename) are not in that always-on context. They only get applied if the model decides to fetch AGENTS.md.

For hard safety gates, the critical rules need to live in the always-on file itself. Best practice is a two-tier approach:

• .cursor/index.mdc (alwaysApply: true) — 15–20 lines max: the 3–5 non-negotiables + pointer to AGENTS.md for details
• AGENTS.md — full reference, read on demand for complex tasks

Recommended addition to .cursor/index.mdc:

## Non-negotiables (always apply)
- NEVER edit a function/class/method without running `gitnexus_impact` first.
- NEVER rename symbols with find-and-replace — use `gitnexus_rename`.  
- NEVER commit without running `gitnexus_detect_changes()`.
- NEVER ignore HIGH/CRITICAL risk warnings.
- NEVER run `npx gitnexus analyze` without `--embeddings` if `.gitnexus/meta.json` shows stored embeddings.

Full rules → **AGENTS.md** (`gitnexus:start` block, Cursor Cloud section).

This adds ~200 tokens to every Cursor request but guarantees the safety gates are applied — far better than the current approach where they might be skipped.

---

🟡 Medium: Scope Table Repeated 3× Across Files

The read/write/execute/off-limits table appears in AGENTS.md, CLAUDE.md, and GUARDRAILS.md with essentially the same content. This costs ~300–400 tokens per file that gets loaded and adds maintenance burden (update one, forget the others).

Recommended: Keep it only in AGENTS.md as the single source of truth. CLAUDE.md and GUARDRAILS.md should reference it via a link, not re-state it.

---

🟡 Medium: No Cursor Rule for eval/

.cursor/rules/100-monorepo.mdc has globs gitnexus/** and gitnexus-web/** but nothing for eval/**. Python/eval contributors working in that directory get no guidance about the uv run stack, Hypothesis tests, or the bridge timeout constants. A 10-line 200-eval.mdc with Python-specific commands would close this gap.

---

🟢 Good: Structural Patterns That Are Correct

Pattern	Why it's right
.cursor/index.mdc as pointer, not content dump	Follows Cursor's recommended rule architecture; avoids putting stale rules in an always-on file
Glob-scoped rules in .cursor/rules/*.mdc	Correct — context is injected only when working on matching files, not for every request
Deprecating .cursorrules	Right call; .cursorrules is loaded for legacy compatibility only
GUARDRAILS.md "Signs" pattern	Excellent LLM prompt engineering — trigger/instruction/reason triples are highly effective for consistent agent behavior
llms.txt for context seeding	Follows the llms.txt convention correctly; good for RAG-style tooling
Self-referential indexing (the repo indexed by GitNexus itself)	Genuinely clever and architecturally sound; closes the loop for AI-assisted contributions

---

🔵 Minor: llms.txt Could Be More Useful

Current llms.txt lists files without explaining priority or usage context. LLM-aware tools that consume llms.txt benefit from brief annotations:

# Core docs (read first for any contribution)
AGENTS.md — canonical agent instructions, GitNexus MCP tool reference
GUARDRAILS.md — non-negotiables and escalation triggers

# Operational (read when running commands or debugging)
RUNBOOK.md — copy-paste commands for common workflows
TESTING.md — test commands for both packages

---

Token Budget Summary

Item	Est. tokens	Status
gitnexus:start block in CLAUDE.md	~700/session	❌ Remove
gitnexus:start block doubled in AGENTS.md	~700 when read	❌ Fix
Scope table ×3	~400/file loaded	🟡 Consolidate
.cursor/index.mdc always-on	~113/Cursor req	🟡 Expand to ~250 with critical rules
100-monorepo.mdc on-match	~125	✅ Appropriate

The two critical fixes (remove block from CLAUDE.md, fix AGENTS.md double-embed) would save ~700–1,400 tokens per session with zero loss of information, since AGENTS.md remains the authoritative source.

---

Summary

The direction is correct — layered docs, glob-scoped Cursor rules, pointer-based always-on context, and self-referential indexing are all sound patterns. The issues are execution-level: the gitnexus:start block was accidentally duplicated into CLAUDE.md (and doubled inside AGENTS.md), and .cursor/index.mdc is too minimal to guarantee the critical safety rules are applied in every Cursor session. Fix those two things and this framework is solid.
