Core concepts

-# Cortex memory and AI providers - -
Route bounded, evidence-backed repository context to Claude, Codex/OpenAI, or Ollama without mixing unverified model output into trusted run memory.
- -Cortex is AgentDiff's provider-neutral intelligence layer. It is not a second agent framework and it does not silently execute model output. It connects verified transaction evidence to an explicitly selected API or local client. - -## Architecture - -Each request passes through four isolated stages: - -1. **Evidence memory** reads completed AgentDiff transaction cards from `.agentdiff/memory.json`. -2. **Hybrid retrieval** ranks cards using task and path overlap, recency, policy risk, and optional semantic vectors. -3. **Context packing** labels clean runs separately from prior `review` or `deny` findings and applies a strict result limit. -4. **Provider routing** sends the current task and context to exactly one configured provider. - -This follows the useful provider-isolation pattern in [Hermes Agent memory providers](https://hermes-agent.nousresearch.com/docs/user-guide/features/memory-providers/), while applying an AgentDiff-specific trust rule: model responses are unverified and are **never** written into the evidence store. A later `agentdiff run` records the actual verified state instead. - -## Supported providers - -| Provider | Cortex adapter | Default behavior | -|---|---|---| -| OpenAI / Codex API | `openai-api` or `codex-api` | Responses API, `gpt-5.6-terra`, medium reasoning, persisted reasoning context | -| Codex client | `codex-cli` | Ephemeral `codex exec` session with a read-only sandbox | -| Anthropic API | `anthropic-api` or `claude-api` | Messages API, `claude-sonnet-5` | -| Claude Code client | `claude-cli` | Non-persistent print session in plan permission mode | -| Ollama API | `ollama-api` | Native `/api/chat`; the local model is required | -| Ollama client | `ollama-cli` | `ollama run`; the local model is required | - -The OpenAI adapter uses the current [Responses API model guidance](https://developers.openai.com/api/docs/guides/latest-model), including `previous_response_id` for a continued response. Anthropic's current [model IDs](https://platform.claude.com/docs/en/about-claude/models/model-ids-and-versions) use a dateless pinned format for Claude 4.6 and newer. Ollama uses its native [chat](https://docs.ollama.com/capabilities/tool-calling) and [embedding](https://docs.ollama.com/capabilities/embeddings) endpoints; its OpenAI-compatible Responses layer does not preserve `previous_response_id`, so Cortex does not pretend that it does. - -## Memory trust classes - -Cortex treats a previous run according to its recorded outcome: - -- `ALLOW` is a verified clean-run example. -- `REVIEW` and `DENY` are warnings and never successful implementation examples. -- generated skill cards remain explicit files under `.agentdiff/skills/` and include their originating capsule ID. -- raw prompts, API keys, and provider responses are not added to trajectory memory. - -This keeps useful long-term context without allowing a plausible model answer to become repository truth. - -## Hybrid retrieval - -Local retrieval works without a model or network connection. Its deterministic score combines: - -- task and symbol/path term overlap; -- exact path matches; -- recency decay over recorded episodes; and -- higher visibility for risky historical findings. - -Optional Ollama embeddings add semantic similarity to the score. They enrich the index; they do not replace deterministic evidence signals. - -```bash -ollama pull embeddinggemma -agentdiff cortex memory index --model embeddinggemma -agentdiff cortex memory search "authentication session regression" --embedding-model embeddinggemma -``` - -The embedding vectors remain in `.agentdiff/memory.json`. The text sent to the local embedding endpoint is the compressed card—not the full evidence capsule or raw file contents. - -## Per-turn hooks - -`RepositoryMemoryProvider` exposes the same lifecycle a provider plugin needs: - -```python -from agentdiff import CortexRouter, RepositoryMemoryProvider, create_provider - -provider = create_provider("ollama-api", model="qwen3.6") -memory = RepositoryMemoryProvider(".", max_memories=4) -router = CortexRouter(provider, memory=memory, root=".") - -result = router.ask("Plan the smallest safe authentication fix") -print(result.response.text) -router.shutdown() -``` - -`prefetch()` runs before the request, `sync_turn()` runs after it, and `shutdown()` releases provider resources. The built-in repository provider deliberately makes `sync_turn()` a no-op because the returned model text has not been verified. - -## Safety boundary - -API adapters return text and expose no execution tools. Local Claude and Codex clients can inspect the repository, but Cortex starts them in plan/read-only modes. To make changes, run an explicit agent command through the normal transaction boundary: - -```bash -agentdiff run --task "Fix authentication" -- codex -``` - -Provider APIs can incur cost and send the packed task context to the configured service. Ollama stays local when its endpoint points to localhost.

04 Generate Changes
-
-

Deterministic transforms.
Agent fallback.

-

Known migrations use deterministic AST transforms with 100% precision. Complex migrations fall back to a supervised coding agent. Either way: the patch is untrusted until AgentDiff proves it.

-
-
-
- DETERMINISTIC - AST Transforms -

Provider-extensible transforms for known breaking changes. Zero hallucination risk, exact AST syntax trees.

-
-
- SUPERVISED - Agent Fallback -

Coding agents handle arbitrary multi-file refactoring, but output is sandboxed and treated as unproven input.

-
-
- POLICY CORE - Untrusted by Default -

Regardless of source, no code reaches your repository without passing the deterministic verification engine.

07 Differentiation
-
-

Not another coding agent.
The trust layer.

-

Coding agents generate code. Dependabot bumps versions. Neither scores blast radius, verifies changes in clean rooms, or attaches cryptographic proof. AgentDiff is the verifier between generation and deployment.

08 Under The Hood
-
-

Trust engine
architecture.

-

Built on deterministic foundations: no-follow filesystem scanning, tamper-evident SHA-256 digests, warm isolated workspaces, and safe promotion.

-
-
-
- PROOF ENGINE - Clean-Room Replay -

Every patch is replayed in a fresh, isolated worktree. Syntax, types, and test suites run from scratch with zero leakage from the agent environment.

-
-
- EVIDENCE - Durable Capsules -

Captures before/after manifests, SHA-256 checksums, policy provenance, blast-radius components, and process identifiers in a versioned local capsule.

-
-
- RECOVERY - Selective Rollback -

Targeted undo for review and deny mutations without blowing away allowed work. Human edits become conflicts and are safely preserved.

-
-
-
-
- REPAIR LOOP - Bounded Retries -

When proof fails, the automatic repair loop retries the patch—strictly bounded to the initial task scope. No infinite agent loops.

-
-
- POLICY ENGINE - Deterministic Rules -

Fine-grained path rules with explicit provenance. Every mutation is categorized with allow, review, or deny and audit trail.

-
-
- WARM WORKSPACES - Zero Cold Starts -

Pre-warmed workspace snapshots enable sub-second clean-room verification runs without costly dependency reinstallations.

-

09 Honest Boundaries
-

Evidence, not
security theater.

-
-
-

The local runtime observes a subprocess. It does not pretend to be a kernel sandbox just because an AI agent executed the command.

-
    -
  • Does capture no-follow filesystem state and versioned evidence
    • -
  • Does enforce command mutation policy before local process launch
    • -
  • Does not block network access in local observation mode
    • -
  • Does not claim causal ownership of machine-wide port changes
    • -
- Read the full security trust model -
