Session 20251228-201509

Started: 2025-12-28 20:15:09 Task: Skills exploration and session search setup

Context

• Branch: main
• Recent commits: 1238ed6f fix: use floor_char_boundary for safe UTF-8 string truncation 1b5f4724 fix: role switching now updates service config in REPL bbd3a836 feat: add local-knowledge skill infrastructure

Session Goals

1. Explore available Terraphim skills
2. Set up session search functionality
3. Review current branch status

Progress Log

• 20:15 - Session started
• 20:15 - Installed terraphim-engineering-skills plugin
• 20:15 - Checked main branch status (12 modified, 6 untracked files)

Decisions & Discoveries

• terraphim-agent binary exists but lacks 'sessions' subcommand
• Session data available in ~/.claude/projects/
• Found 5+ sessions mentioning 'architecture'

Blockers

• None currently

Phase 1 & 2 Complete

Research Document

docs/sessions/research-underutilized-features.md

Design Document

docs/sessions/design-underutilized-features.md

Key Design Decisions

1. Advisory pre-LLM validation (not blocking)
2. Role detection: --role > env > config > default
3. New checklist:: directive for KG checklists
4. 200ms hook timeout budget
5. Skill-invoked smart commits (not automatic)

Implementation Phases

• A: Fix MCP + CLI infrastructure (4 steps)
• B: New CLI commands (5 steps)
• C: Skills & hooks (6 steps)
• D: KG extensions (4 steps)
• E: Integration & docs (4 steps)

Phase A Complete - $(date '+%Y-%m-%d %H:%M')

Commit

a28299fd fix(mcp): wire is_all_terms_connected_by_path to real RoleGraph implementation

Changes Made

1. MCP Connectivity Fix - crates/terraphim_mcp_server/src/lib.rs

   • Removed placeholder implementation
   • Gets RoleGraphSync from config_state.roles
   • Calls real is_all_terms_connected_by_path() method
   • Returns detailed connectivity results

2. Test Updates - crates/terraphim_mcp_server/tests/test_advanced_automata_functions.rs

   • Updated tests to use text parameter instead of terms array
   • Added role-specific test case
   • All 4 tests pass

Verification

• All pre-commit checks passed (fmt, clippy, build, tests)
• MCP connectivity now calls real graph algorithm

Phase B Progress - $(date '+%Y-%m-%d %H:%M')

Commit

11f13a4f feat(cli): add validate and suggest commands

New Commands Implemented

terraphim-agent validate

# Check semantic connectivity
terraphim-agent validate --connectivity "haystack service uses automata"
# Output: Connected: true/false, Matched terms: [...]

# JSON output for hook integration
terraphim-agent validate --connectivity --json "text"

terraphim-agent suggest

# Fuzzy suggestions for typos
terraphim-agent suggest "terraphm" --threshold 0.7
# Output: terraphim-graph (similarity: 75.4), ...

# JSON output
terraphim-agent suggest --json "query"

Files Changed

• crates/terraphim_agent/src/service.rs - Added check_connectivity() and fuzzy_suggest() methods
• crates/terraphim_agent/src/main.rs - Added Validate and Suggest subcommands

Remaining Phase B Tasks

• B3: validate --checklist (domain checklist validation)
• B4: hook unified handler
• B5: Unit tests

Phase B Complete - $(date '+%Y-%m-%d %H:%M')

Commits

11f13a4f feat(cli): add validate and suggest commands
f7af785d feat(cli): add validate --checklist for domain validation
4b701b0c feat(cli): add unified hook handler for Claude Code integration

New CLI Commands Summary

| Command | Description | |---------|-------------| | validate | Basic match validation against KG | | validate --connectivity | Check semantic coherence via graph path | | validate --checklist NAME | Validate against domain checklist | | suggest --fuzzy | Fuzzy autocomplete suggestions | | hook --hook-type TYPE | Unified Claude Code hook handler |

Hook Types

• pre-tool-use - Intercepts Bash commands for replacement
• post-tool-use - Validates tool output via connectivity
• pre-commit - Extract concepts from diff
• prepare-commit-msg - Enhance commit with concepts

Remaining

• B5: Unit tests (optional - functional tests pass)
• Phase C: Skills & Hooks (create skill files)
• Phase D: KG Extensions
• Phase E: Integration & Documentation

Phase C Complete - $(date '+%Y-%m-%d %H:%M')
