Functions

func DeleteModelCapability added in v0.6.0 

func DeleteModelCapability(database *db.DB, modelID string) error

DeleteModelCapability clears a model's cached capability so it is re-probed on next use. An empty modelID clears every cached capability. Used by the manual-refresh path.

func DeleteModelPreference 

func DeleteModelPreference(database *db.DB, id string) error

DeleteModelPreference removes a model preference from the database.

func Now 

func Now() int64

func SetMemoryConfig added in v0.2.1 

func SetMemoryConfig(database *db.DB, c *MemoryConfig) error

SetMemoryConfig upserts the agentic-memory config row (id is always 1). Legacy embed/chat columns are reset to defaults — they are no longer used.

func SetModelCapability added in v0.6.0 

func SetModelCapability(database *db.DB, c *ModelCapability) error

SetModelCapability upserts a probed capability record for a model.

func SetModelPreference 

func SetModelPreference(database *db.DB, p *ModelPreference) error

SetModelPreference upserts a model preference into the database.

func SetProviderConfig added in v0.2.1 

func SetProviderConfig(database *db.DB, c *ProviderConfig) error

SetProviderConfig upserts a provider config row.

func SetSearchConfig added in v0.8.0 

func SetSearchConfig(database *db.DB, c *SearchConfig) error

SetSearchConfig upserts the singleton config row.

Types

type ImagePartData added in v0.14.0 

type ImagePartData struct {
	MediaType string `json:"mediaType"`
	Data      string `json:"data"`
	Name      string `json:"name,omitempty"`
}

ImagePartData stores a user-uploaded image attachment. Data is base64-encoded image bytes; MediaType is e.g. "image/jpeg" or "image/png". The Name field carries the original filename (optional, for display only).

type MemoryConfig added in v0.2.1 

type MemoryConfig struct {
	Enabled   bool  `json:"enabled"`
	UpdatedAt int64 `json:"updatedAt"`
}

MemoryConfig holds the user's agentic-memory configuration stored in the DB.

Embedding is always produced by the inbuilt local embedder (all-MiniLM-L6-v2) — there is no embedder configuration. The synthesis LLM is not configured here either: it uses the session's selected model at call time. So the only persisted knob is whether agentic memory is enabled.

The underlying memory_config table still carries legacy embed/chat columns from earlier releases; they are no longer read or written by this struct but are retained in the schema for migration safety.

func GetMemoryConfig added in v0.2.1 

func GetMemoryConfig(database *db.DB) (*MemoryConfig, error)

GetMemoryConfig returns the stored agentic-memory config. If the row does not exist, agentic memory defaults to enabled: the inbuilt local embedder (all-MiniLM-L6-v2) needs zero setup — no API key, no external service — so memory is on out of the box. A user who has explicitly turned memory off has a persisted row with enabled = 0, which is still honored.

func MaskedMemoryConfig added in v0.2.1 

func MaskedMemoryConfig(c *MemoryConfig) *MemoryConfig

MaskedMemoryConfig returns a copy of c. With the embed/chat fields gone there are no secrets to mask, but the function is retained for API compatibility.

type MessageID 

type MessageID = id.MessageID

func NewMessageID 

func NewMessageID() MessageID

type MessageInfo 

type MessageInfo struct {
	ID        MessageID    `json:"id"`
	SessionID SessionID    `json:"sessionId"`
	Role      MessageRole  `json:"role"`
	Agent     string       `json:"agent,omitempty"`
	ParentID  *MessageID   `json:"parentId,omitempty"`
	Finish    *string      `json:"finish,omitempty"`
	Cost      float64      `json:"cost,omitempty"`
	Tokens    *TokenCounts `json:"tokens,omitempty"`
	Error     *string      `json:"error,omitempty"`
	CreatedAt int64        `json:"createdAt"`
}

type MessageRole 

type MessageRole string
const (
	RoleUser      MessageRole = "user"
	RoleAssistant MessageRole = "assistant"
)

type MessageWithParts 

type MessageWithParts struct {
	Info  MessageInfo `json:"info"`
	Parts []Part      `json:"parts"`
}

type ModelCapability added in v0.6.0 

type ModelCapability struct {
	ModelID        string `json:"modelId"`
	SupportsImages bool   `json:"supportsImages"`
	ProbedAt       int64  `json:"probedAt"`
}

ModelCapability is a probed/known capability record for a model, persisted so the image-support probe runs at most once per model (until manually refreshed).

func GetModelCapability added in v0.6.0 

func GetModelCapability(database *db.DB, modelID string) (*ModelCapability, bool, error)

GetModelCapability returns the persisted capability record for a model. The second return value is false when no record exists (not yet probed).

type ModelPreference 

type ModelPreference struct {
	ID          string `json:"id"`
	Enabled     bool   `json:"enabled"`
	ProviderID  string `json:"providerId"`
	DisplayName string `json:"displayName"`
	IsCustom    bool   `json:"isCustom"`
	// Collection is an optional group name for custom models so OpenAI-compatible
	// providers added through the OpenAI provider (Gemini, DeepSeek, Groq, …) can
	// be grouped together in the UI instead of all collapsing under "OpenAI".
	// Empty for built-in models and legacy custom models (falls back to providerId).
	Collection string `json:"collection"`
	CreatedAt  int64  `json:"createdAt"`
	UpdatedAt  int64  `json:"updatedAt"`
}

	Type      PartType        `json:"type"`
	Data      json.RawMessage `json:"data"`
	CreatedAt int64           `json:"createdAt"`
	UpdatedAt int64           `json:"updatedAt"`
}

func MaskedProviderConfig added in v0.2.1 

func MaskedProviderConfig(c *ProviderConfig) *ProviderConfig

MaskedProviderConfig returns a copy with the API key replaced by a sentinel so it can be sent to the UI without leaking the real value.

}

type SearchConfig added in v0.8.0

	Permission        string    `json:"permission,omitempty"`
	CompactionSummary string    `json:"compactionSummary,omitempty"`
	MemoryTokensSaved int       `json:"memoryTokensSaved,omitempty"`

func (*Store) DeleteMessage added in v0.19.1 

func (s *Store) DeleteMessage(messageID MessageID) error

DeleteMessage removes a message and all of its parts. Foreign-key cascade handles part deletion automatically. Used to clean up partial assistant messages left behind when mid-loop guidance cancels a text-only stream — keeping them would produce two consecutive assistant role messages on the next prompt, which the Anthropic and OpenAI APIs reject with a 400.

func (*Store) Get 

func (s *Store) Get(id SessionID) (*Session, error)

func (*Store) GetMessage 

func (s *Store) GetMessage(messageID MessageID) (*MessageWithParts, error)

func (*Store) List 

func (s *Store) List(directory string) ([]*Session, error)

func (*Store) Update 

func (s *Store) Update(session *Session) error

func (*Store) UpdateCompactionSummary 

func (s *Store) UpdateCompactionSummary(id SessionID, summary string) error

UpdateCompactionSummary updates only the compaction_summary column for a session, avoiding the race condition of overwriting other fields (e.g., title, model) that may have changed concurrently.

func (*Store) UpdateMemoryTokensSaved added in v0.2.1 

func (s *Store) UpdateMemoryTokensSaved(id SessionID, delta int) error

UpdateMemoryTokensSaved atomically increments memory_tokens_saved by delta (may be negative). delta is clamped above at 1_000_000_000 to prevent overflow; negative values are preserved so callers can track memory overhead accurately.
