Summary

This PR addresses documentation gaps identified during the Update Docs workflow review by adding three key documentation components following the Diátaxis framework.

Changes

1. API Reference (docs/api-reference.md)

Complete Python library documentation for developers extending Mnemonic:

  • lib.paths: PathResolver, PathContext, Scope, convenience functions
  • lib.search: Memory search, scoring, duplicate detection
  • lib.memory_reader: Metadata extraction from memory files
  • lib.relationships: Relationship management, type conversion
  • lib.ontology: Ontology loading and pattern management
  • lib.config: Configuration management

Includes:

  • Class and function signatures
  • Usage examples
  • Testing guidance
  • Complete workflow examples

2. Troubleshooting Guide (docs/troubleshooting.md)

Comprehensive troubleshooting for common issues:

  • Installation problems (missing dependencies, permissions)
  • Hook failures (SessionStart, PreToolUse, PostToolUse)
  • Search issues (ripgrep, paths, case sensitivity)
  • Git remote detection
  • Ontology validation errors
  • Memory file format issues
  • Performance optimization
  • Relationship debugging

Each issue includes:

  • Symptom description
  • Step-by-step solution
  • Verification steps

3. Tutorial Framework (docs/tutorials/)

Learning-oriented step-by-step guides:

  • README.md: Tutorial index with learning paths

    • Beginner: Developers building project documentation (1.5 hrs)
    • Intermediate: Teams sharing organizational memory (2 hrs)
    • Advanced: Power users customizing the system (4 hrs)
  • getting-started.md: First project setup tutorial

    • Git remote configuration
    • Plugin installation
    • Directory initialization
    • Creating first memory
    • Verification checklist

4. Updated README.md

Reorganized documentation table to prioritize:

  1. Getting started tutorial (new)
  2. Tutorial index (new)
  3. API reference (new)
  4. Troubleshooting guide (new)
  5. Existing guides

Pull request overview

This PR expands Mnemonic’s documentation set to better cover the Diátaxis categories by adding a Python API reference, a troubleshooting guide, and a tutorials landing page + getting-started tutorial, and then surfacing these in the root README.

Changes:

  • Add a new Python API reference documenting core lib/* modules.
  • Add a comprehensive troubleshooting guide for installation, hooks, search, ontology, and relationships.
  • Add a tutorials index and a “First Project Setup” getting-started tutorial, and link these from the README.

These advanced tutorial links (agent-coordination.md, maintenance.md, custom-skills.md) are not present in docs/tutorials/, so the links are currently broken. Add the missing tutorial pages or update the index to point to existing documentation files.

The expected directory tree here shows .git/ under ~/.claude/mnemonic/your-org/, but /mnemonic:setup initializes git at the memory store root (e.g., ~/.claude/mnemonic/.git). Adjust the example structure so users look in the correct place for git history.

The tutorial asserts a project-level .claude/mnemonic/config.yaml, but the repo’s configuration is stored in ~/.config/mnemonic/config.json (see lib/config.py and commands/setup.md). If you intend to document a project-local YAML config, it needs to exist in the implementation; otherwise update these paths/filenames to match the current config mechanism.

This suggests verifying the memory root via ~/.claude/mnemonic/config.yaml, but the implementation uses XDG config at ~/.config/mnemonic/config.json (see lib/config.py and commands/setup.md). Update the troubleshooting steps to point to the correct config file / command for printing the configured memory root.

Suggested change
# Verify memory root in config
cat ~/.claude/mnemonic/config.yaml
# Verify memory root in config (XDG)
cat ~/.config/mnemonic/config.json

These /mnemonic:gc examples use flags that the command doesn’t support (e.g., --older-than and --namespace aren’t defined in commands/gc.md). Please update the troubleshooting commands to the actual supported arguments (--dry-run, --archive, --compress, etc.) so users can follow them successfully.

/mnemonic:gc --dry-run
# Compress old memories
/mnemonic:gc --compress --older-than 90d

The "Expected output" for /mnemonic:status doesn't match the actual implementation in commands/status.md (different headings/fields, and it doesn’t print an ontology line like Ontology: loaded (.claude/mnemonic/ontology.yaml)). Consider either updating this expected output to mirror the real command output or adjusting /mnemonic:status to produce the documented fields.

Suggested change
**Expected output:**
````
✓ Memory root: ~/.claude/mnemonic/
✓ Organization: your-org
✓ Project: your-project
✓ Ontology: loaded (.claude/mnemonic/ontology.yaml)
**Example output (will vary by project):**

✓ Memory root: ~/.claude/mnemonic/

/mnemonic:custodian uses subcommands (e.g., /mnemonic:custodian validate-links [--fix]) rather than --validate-links flags (see commands/custodian.md). Update these examples to the correct invocation syntax so they work as documented.

This list of "Valid default types" doesn’t match the actual relationship registry in lib/relationships.py (which defines types like relates_to/RelatesTo, derived_from/DerivedFrom, supersedes/SupersededBy, conflicts_with, part_of/contains, uses/used_by, etc.). Please update the list to reflect the supported MIF relationship types so users don’t try to use nonexistent ones like depends_on or caused_by.

MNEMONIC_DEBUG and the suggested log path ~/.claude/logs/mnemonic.log don’t appear to be used/created anywhere in the codebase (no references in hooks/ or lib/). This section should either be updated to the actual debugging mechanism supported by Mnemonic or removed to avoid sending users on a dead end.

Suggested change
````bash
# Set debug environment variable
export MNEMONIC_DEBUG=1
# Run command
/mnemonic:status

The Makefile doesn’t define test-hooks or test-lib targets (it has make test, make lint, make validate, etc.). Update these commands to targets that actually exist so the troubleshooting steps are actionable.
