GitHub Actions CI is green for the exact commit. +3. `npm run verify` succeeds from a clean checkout. +4. `npm pack --dry-run` contains only the intended package files. +5. README, SECURITY, LICENSE and `.env.example` match the implementation. +6. No active credentials or local `.cos` state are present in the package/repository diff. +7. Any compatibility/model-default change has been checked against provider documentation or live model discovery. +8. The version/changelog accurately describes breaking behavior. -## 2. Direct Installation for Users -Even without NPM, people can use your tool immediately by cloning or using `npx`. +## Local release verification + +Use a clean clone or clean worktree: + +```bash +npm ci +npm run verify +npm pack --dry-run +``` + +`npm run verify` executes typecheck, production build and the integration/regression tests. `prepublishOnly` invokes the same verification gate automatically, but that is a backstop rather than a replacement for reviewing the result. + +## Package inspection + +`package.json` restricts the package payload to the compiled distribution and release documentation.

If Docker is unavailable, Codebase OS refuses native shell execution by default.

The sandbox currently provides: -While other agents crash on large codebases, Codebase OS is architected for the enterprise monorepo. +- read-only source bind mount; +- disposable writable workspace; +- read-only container root filesystem; +- network disabled unless the requested command is a recognized install/fetch operation; +- CPU, memory, PID, output-size and wall-time limits; +- dropped Linux capabilities and `no-new-privileges`; +- `.git` and `.cos` masking; +- credential-shaped file masking (`.env`, registry credentials, PEM/key files, service-account/credential JSON patterns); +- no inherited application credentials by default; +- explicit environment forwarding only through `COS_SANDBOX_ENV_ALLOW`; +- language-specific container images for supported verification commands. -* **Streaming Scanner**: Processes 1M+ files in bounded memory windows (200 files at a time). Never hits the Node.js 1.5GB heap limit. -* **Two-Stage Vector Search**: $O(1)$ retrieval using SQL-side "Sketch" pre-filtering. Scans 100k+ code chunks in milliseconds without loading blobs into JS memory. -* **Persistent Cognitive State**: Replaces the "Sliding Window" with an LLM-compressed session summary. The agent remembers critical discoveries from Step 1 even at Step 50. -* **Adaptive Topological Planning**: Centrality-weighted graph traversal. Hub nodes get deep blast-radius analysis (up to depth 20), while leaves remain shallow. +The sandbox is a defense layer, not a proof that arbitrary build dependencies are benign. Network-enabled package installation still executes third-party package lifecycle code inside the isolated container. ---- +## Provider configuration -## Under the hood +Supported provider families are OpenAI, Anthropic, Gemini, OpenRouter and Ollama. Provider instances are cached per credential **and model**, preventing a request for one model from accidentally reusing an instance configured for another. -- **Relationship Graph**: Persistent SQLite-backed directed graph with $O(1)$ reverse indexing and Kahn's topological sort. -- **Cognitive State**: Three-tier memory (Working / Session / Long-term) with LLM-based compression and SQLite persistence. -- **Execution model**: Unified diff patching with path-sandbox validation. Read-only project mounts and ephemeral write volumes. -- **Security**: Prompt injection scrubbing for all external data. Meta-character rejection engine for shell execution. -- **Persistence**: Optimized SQLite core with WAL mode, busy timeouts, and 512MB memory-mapped I/O for massive corpora. -- **SSE Dashboard**: Real-time step streaming and task-plan tracking at localhost:3000. +Codebase OS uses semantic roles (`reasoning-high`, `reasoning-fast`, `analysis-fast`, `design-premium`, `embedding-small`) rather than treating a permanent hard-coded model leaderboard as truth. Exact IDs can be pinned without changing source code, for example: ---- +```bash +COS_OPENAI_REASONING_HIGH_MODEL=... +COS_ANTHROPIC_REASONING_HIGH_MODEL=... +COS_GEMINI_ANALYSIS_FAST_MODEL=... +OPENAI_EMBEDDING_MODEL=... +GEMINI_EMBEDDING_MODEL=... +``` -## Providers +Provider defaults are compatibility defaults, not benchmark claims. Model availability, account entitlements and provider limits can change independently of Codebase OS. -Works with every major provider and routes by task type: +## Retrieval -| Provider | Models | Notes | -|:---|:---|:---| -| Anthropic | claude-3-5-sonnet, claude-3-5-haiku | Recommended for reasoning tasks | -| OpenAI | gpt-4o, gpt-4o-mini, o1 | Strong for code generation | -| Google | gemini-2.0-flash, gemini-1.5-pro | Fast, high context window | -| Ollama | qwen2.5-coder, deepseek-coder, llama3 | Fully local, zero API cost | +Semantic retrieval is hybrid: code-body embeddings are combined with keyword retrieval and typed graph context. The current local vector implementation is **not an ANN index** and does not claim O(1) lookup. For larger corpora it performs an O(N) scan over compact deterministic sketches and loads full vectors only for the best candidates before exact cosine re-ranking. ---- +This keeps full-vector memory bounded relative to corpus size, but it is not a substitute for HNSW/DiskANN-class infrastructure at very large enterprise scale. + +## Persistent engineering memory + +Durable state lives in `.cos/cos.db` and includes: + +- graph nodes and edges; +- file analyses/hashes; +- change transactions; +- impact/synchronization reports; +- failure snapshots; +- checkpoints; +- response cache; +- embedding cache; +- cognitive summaries/facts. + +Project memory is based on recorded engineering evidence such as changed files and recurring failure snapshots. It is not advertised as perfect recollection of every previous chat token. + +## Propagation safety + +`cos propagate` does not use a stale pre-save graph. Before impact planning it re-scans the changed dependency. It then analyzes only downstream dependents, applies candidate patches through the transactional patch tool, re-scans changed targets, and runs independent project verification. + +If verification fails, the propagation batch is reverted when the files still match the generated post-change state. Conflicts are surfaced instead of overwriting newer work. + +## Local dashboard + +The dashboard binds only to `127.0.0.1`, applies browser security headers, constrains static file serving to the UI root, rejects non-local/cross-origin approval mutations, and falls back to an available loopback port if the preferred port is busy. + +## CI and release gate + +The repository CI runs on Node 20 and requires: + +```text +npm ci +npm run typecheck +npm run build +npm test +npm pack --dry-run +``` + +`npm run verify` combines typecheck, build and tests, and `prepublishOnly` executes the same verification gate. + +A green badge means the actual GitHub Actions workflow succeeded for that ref. This README deliberately does not use a static “passing” badge. + +## Current scope and non-claims + +Codebase OS is designed to be a trustworthy software-change runtime, but the following are **not** claimed by the current implementation: + +- no claim of being “100× better” than another coding agent without controlled benchmark evidence; +- no guarantee that a one-million-file repository fits in Node memory—the persistent graph is still materialized in memory; +- no O(1) vector-search claim; +- no claim that LLM-generated summaries are lossless memory; +- no claim that static dependency connectivity alone proves causal impact; +- no claim that every programming language has equivalent diagnostic/build coverage; +- no claim that AI propagation is correct unless the independent verification evidence succeeds. + +These are engineering constraints, not marketing footnotes. Future scale/accuracy claims should be attached to reproducible benchmark artifacts. + +## Development + +```bash +npm ci +npm run typecheck +npm run build +npm test +npm run verify +``` -## Who this is for +Tests currently include regression coverage for dependency-first planning and context-validated transactional patches.

The sandbox uses a disposable writable workspace, read-only source mount/container root, resource limits, dropped capabilities, `no-new-privileges`, credential-file masking and network-off defaults. + +If Docker is unavailable, native command execution is **blocked by default**. `COS_ALLOW_NATIVE_SANDBOX=1` is an explicit reduced-isolation override and should not be used for untrusted repositories. + +### Credentials + +The Docker sandbox does not inherit the parent process environment by default. Environment forwarding is explicit through `COS_SANDBOX_ENV_ALLOW`. + +Credential-shaped repository files such as `.env`, registry credential files, PEM/private-key files and service-account/credential JSON patterns are masked before repository contents are copied into the disposable workspace. Example/template env files are not treated as secrets unless they match another credential rule. + +This is defense in depth, not a secret-detection completeness guarantee. Do not store production credentials in source repositories. + +### Network + +Container networking is disabled for normal build/test commands. It is enabled only for recognized dependency installation/fetch operations (or explicit internal calls that require network). A network-enabled package installation may execute third-party lifecycle code inside the container; it should not be treated as trusted merely because it runs in Docker. + +### Dashboard + +The local dashboard binds to `127.0.0.1`. Static file serving is constrained to the packaged UI root, and mutation endpoints reject non-local/cross-origin requests. Do not expose the dashboard through a reverse proxy or port-forward without adding authentication and transport security appropriate to that environment. + +### Model/source prompt injection + +Repository text included in retrieval/propagation context is labeled as untrusted data. Scanner ingestion also removes several common prompt-instruction marker patterns before embedding. Pattern scrubbing is not a complete prompt-injection defense; tool policy, path isolation, transactional mutation and independent verification are the authoritative safety boundaries. + +## Verification boundary + +A model cannot certify its own mutation. After changes, the independent verification kernel discovers applicable project gates and executes them separately. If code changed and no supported verification strategy exists, completion fails closed. + +A green verification result proves only the checks that actually ran. It does not mathematically prove absence of security vulnerabilities, logic errors or missing tests. + +## Rollback boundary + +Rollback is conflict-aware. A transaction is reversed only if the filesystem still matches the recorded post-change state. If a developer or later automation changed the same file, rollback stops rather than overwriting newer work. + +## Recommended operating practice + +- Use a clean Git worktree/branch for autonomous changes. +- Keep Docker running and leave native execution disabled. +- Use least-privilege, short-lived development credentials only when a task genuinely requires them. +- Keep sensitive `.env` and credential material outside source control. +- Review generated diffs and verification evidence before merging. +- Protect `main` with CI/branch rules in repositories where Codebase OS is used autonomously. diff --git a/package-lock.json b/package-lock.json index 5880eb3..ef882d9 100644 --- a/package-lock.json +++ b/package-lock.json @@ -18,13 +18,13 @@ "chokidar": "^3.5.3", "cli-table3": "^0.6.3", "commander": "^11.1.0", -
