+# Get ontology file path (precedence order)
+ontology_path = get_ontology_file()
+# Checks: project > user > fallback
+````
+
+**Ontology Resolution** (precedence order):
+1. Project: `.claude/mnemonic/ontology.yaml`
+2. User: `~/.claude/mnemonic/ontology.yaml`
+3. Fallback: `skills/ontology/fallback/ontologies/mif-base.ontology.yaml`
+


The ontology resolution precedence order documentation is incorrect. According to lib/ontology.py lines 24-41, get_ontology_file() only checks for the fallback ontology file at skills/ontology/fallback/ontologies/mif-base.ontology.yaml. It does NOT check project (.claude/mnemonic/ontology.yaml) or user (~/.claude/mnemonic/ontology.yaml) locations. Either the documentation should be updated to reflect the actual implementation, or the implementation needs to be enhanced to support the documented precedence order.

Suggested change

# Get ontology file path (precedence order)

ontology_path = get_ontology_file()

# Checks: project > user > fallback

````

**Ontology Resolution** (precedence order):

1. Project: `.claude/mnemonic/ontology.yaml`

2. User: `~/.claude/mnemonic/ontology.yaml`

3. Fallback: `skills/ontology/fallback/ontologies/mif-base.ontology.yaml`

# Get ontology file path

ontology_path = get_ontology_file()

# Currently resolves to the built-in fallback ontology file:

# skills/ontology/fallback/ontologies/mif-base.ontology.yaml

Ontology Resolution:

Currently, get_ontology_file() resolves only the built-in fallback ontology:

Fallback: skills/ontology/fallback/ontologies/mif-base.ontology.yaml

Project-level (.claude/mnemonic/ontology.yaml) and user-level
(~/.claude/mnemonic/ontology.yaml) ontology files are not currently
used in the resolution process and may be supported in a future version.

+    from_file=Path("decision-a.memory.md"),
+    to_file=Path("decision-b.memory.md"),
+    relationship_type="supersedes",  # snake_case or PascalCase


The parameter names are incorrect. According to lib/relationships.py lines 286-291, the function signature is add_bidirectional_relationship(source_path: str, target_path: str, rel_type: str, label: Optional[str] = None), not add_bidirectional_relationship(from_file, to_file, relationship_type, label=None). The parameters should be source_path and target_path (both str), not from_file and to_file (Path objects). Also, the parameter is rel_type, not relationship_type.

Suggested change

from_file=Path("decision-a.memory.md"),

to_file=Path("decision-b.memory.md"),

relationship_type="supersedes", # snake_case or PascalCase

source_path="decision-a.memory.md",

target_path="decision-b.memory.md",

+    from_file=Path("new-approach.memory.md"),
+    to_file=Path("old-approach.memory.md"),
+    relationship_type="supersedes"
+)


The example code uses incorrect parameter names. According to lib/relationships.py line 286-291, the parameters should be source_path and target_path (str), not from_file and to_file (Path). The parameter name is also rel_type, not relationship_type. The example should use string paths or convert Path objects to strings.

+#### `add_bidirectional_relationship(from_file, to_file, relationship_type, label=None)`


The function signature is incorrect. According to lib/relationships.py line 286-291, the correct signature is add_bidirectional_relationship(source_path: str, target_path: str, rel_type: str, label: Optional[str] = None) -> tuple[bool, bool]. The parameters should be source_path and target_path (not from_file and to_file), the third parameter is rel_type (not relationship_type), and the function returns a tuple of two booleans, not nothing.

+# Get formatted summary (title + first paragraph)
+summary = get_memory_summary(Path("memory.memory.md"), max_lines=3)
+# Returns: "Title: My Decision\n\nFirst paragraph of content..."


The function signature and return type documentation is incorrect. According to lib/memory_reader.py lines 110-156, get_memory_summary has the signature get_memory_summary(path: str, max_summary: int = 300) -> dict and returns a dictionary with keys title and summary, not a formatted string. The parameter is also named max_summary, not max_lines. The correct documentation should show:

Parameter: max_summary: int = 300 (not max_lines)

Return type: dict with keys title (str) and summary (str)

The example return value should be a dict like {"title": "My Decision", "summary": "First paragraph of content..."}

Suggested change

# Get formatted summary (title + first paragraph)

summary = get_memory_summary(Path("memory.memory.md"), max_lines=3)

# Returns: "Title: My Decision\n\nFirst paragraph of content..."

# Get memory summary (title and first paragraph)

summary_info = get_memory_summary("memory.memory.md", max_summary=300)

# Returns: {"title": "My Decision", "summary": "First paragraph of content..."}

+**Returns**:
+- `id` (str): UUID
+- `title` (str): Memory title
+- `type` (str): Memory type (semantic/episodic/procedural)
+- `namespace` (str): Namespace path
+- `tags` (list): Tag list
+- `relationships` (list): Relationship objects


The documented return values are incorrect. According to lib/memory_reader.py lines 182-189, the metadata dict includes the key path (absolute path string), but does NOT include a type field. The correct list of keys should be: id, title, namespace, tags, relationships, summary, path (not type).

+#### `add_relationship(path, target_id, rel_type, label=None)`
+Add single relationship to frontmatter.
+
+**Args**:
+- `path` (Path): Memory file to modify
+- `target_id` (str): Target memory UUID
+- `rel_type` (str): Relationship type (snake_case or PascalCase)


The function signature has incorrect parameter order. According to lib/relationships.py line 188-193, the correct signature is add_relationship(memory_path, rel_type, target_id, label=None), not add_relationship(path, target_id, rel_type, label=None). The rel_type parameter comes before target_id, and the first parameter is named memory_path not path.

Suggested change

#### `add_relationship(path, target_id, rel_type, label=None)`

Add single relationship to frontmatter.

**Args**:

- `path` (Path): Memory file to modify

- `target_id` (str): Target memory UUID

- `rel_type` (str): Relationship type (snake_case or PascalCase)

#### `add_relationship(memory_path, rel_type, target_id, label=None)`

Add single relationship to frontmatter.

**Args**:

- `memory_path` (Path): Memory file to modify

- `rel_type` (str): Relationship type (snake_case or PascalCase)

- `target_id` (str): Target memory UUID

+#### `add_relationship(path, target_id, rel_type, label=None)`
+Add single relationship to frontmatter.
+
+**Args**:
+- `path` (Path): Memory file to modify
+- `target_id` (str): Target memory UUID
+- `rel_type` (str): Relationship type (snake_case or PascalCase)


The parameter names and order in the Args section are incorrect. According to lib/relationships.py lines 200-204, the correct parameter order is: memory_path (not path), rel_type, target_id, label. The first parameter should be documented as memory_path (str): Memory file to modify, not path (Path).

Suggested change

#### `add_relationship(path, target_id, rel_type, label=None)`

Add single relationship to frontmatter.

**Args**:

- `path` (Path): Memory file to modify

- `target_id` (str): Target memory UUID

- `rel_type` (str): Relationship type (snake_case or PascalCase)

#### `add_relationship(memory_path, rel_type, target_id, label=None)`

Add single relationship to frontmatter.

**Args**:

- `memory_path` (str): Memory file to modify

- `rel_type` (str): Relationship type (snake_case or PascalCase)

- `target_id` (str): Target memory UUID

+**Format**:
+````
+Title: {title}
+Type: {type} | Namespace: {namespace}
+
+{first_paragraph}
+````


The format description is incorrect. According to lib/memory_reader.py lines 110-156, get_memory_summary returns a dictionary with keys title and summary, not a formatted multi-line string. The actual format is: {"title": "...", "summary": "..."}. Remove this incorrect format section or update it to show the correct dictionary structure.

Copilot · 2026-02-16T18:17:12Z

+metadata = get_memory_metadata(Path("memory.memory.md"))
+# Returns: {'id': '...', 'title': '...', 'type': 'semantic', ...}
+
+# Get formatted summary (title + first paragraph)
+summary = get_memory_summary(Path("memory.memory.md"), max_lines=3)


The example code uses incorrect parameter types. According to lib/memory_reader.py line 159, get_memory_metadata accepts a string path, not a Path object. Change Path("memory.memory.md") to just "memory.memory.md" or use str(Path("memory.memory.md")).

Suggested change

metadata = get_memory_metadata(Path("memory.memory.md"))

# Returns: {'id': '...', 'title': '...', 'type': 'semantic', ...}

# Get formatted summary (title + first paragraph)

summary = get_memory_summary(Path("memory.memory.md"), max_lines=3)

metadata = get_memory_metadata("memory.memory.md")

# Returns: {'id': '...', 'title': '...', 'type': 'semantic', ...}

# Get formatted summary (title + first paragraph)

summary = get_memory_summary("memory.memory.md", max_lines=3)
