Product boundary

Frigg’s category is local code context for coding agents. It gives agents repository-aware search, navigation, and bounded reads through MCP so their claims can be checked against local source.

What Frigg owns

Frigg owns the local evidence layer:

repository-aware file listing and exact text search
ranked discovery, known-symbol lookup, and multi-probe search
bounded source reads, citations, outlines, and structural queries
read-only definitions, references, implementations, and call navigation
target-first impact analysis with explicit trust and completeness
runtime status for adopted repositories
optional semantic recall, SCIP ingestion, and watch refreshes

What Frigg does not own

Frigg is not an AI pair programmer, IDE replacement, hosted code-intelligence platform, Copilot alternative, generic semantic-search product, framework runtime, or agent operating system.

It also does not control a host’s tool ordering, authorization, MCP registration, or subagent inheritance. If a child session lacks Frigg while its parent has it, repair the host integration or use that child’s allowed fallback; it is not evidence of a search-ranking failure.

Safety and side effects

Normal indexing reads source inside configured workspace roots and writes only Frigg-owned state such as .frigg/storage.sqlite3. It does not edit project source files.

Some optional or explicit operations have wider effects:

frigg adopt writes managed instructions, MCP configuration, optional hooks, and optional copied skills in the project or host skill locations.
Semantic providers can send source-derived embedding inputs to the configured OpenAI, Google, or OpenAI-compatible service. The local provider stays local.
Precise generators can execute repository-local or PATH tools and write .frigg/scip/ artifacts.
The CLI owns explicit maintenance such as frigg init and frigg index. The public MCP product surface has no reindex or source-write tool.

Why the boundary matters

The customer value is not a particular implementation detail. Frigg helps agents find the right files, narrow source windows, follow identities, and leave a traceable path to evidence. Hosts and agents still decide what to change and whether the evidence supports a conclusion.
