**Local source files are not present.** Your workspace does not contain source code. You **MUST** use Sourcegraph MCP tools to discover, read, and understand code before making any changes.
**Target Repositories (version-pinned mirrors):**
- `github.com/sg-evals/chromium--2d05e315` — use `repo:^github.com/sg-evals/chromium--2d05e315$` filter
Scope ALL keyword_search/nls_search queries to these repos.
Use the repo name as the `repo` parameter for read_file/go_to_definition/find_references.
## Required Workflow
1. **Search first** — Use MCP tools to find relevant files and understand existing patterns
2. **Read remotely** — Use `sg_read_file` to read full file contents from Sourcegraph
3. **Edit locally** — Use Edit, Write, and Bash to create or modify files in your working directory
4. **Verify locally** — Run tests with Bash to check your changes
5. **Produce answer.json** — After completing your edits, also write `/workspace/answer.json` summarizing your work:
```json
{
"analysis": {
"summary": "Brief description of your approach",
"files_examined": [{"path": "file.ext", "description": "..."}],
"reasoning": "Detailed explanation or analysis"
},
"changes": [
{"file": "path.ext", "description": "...", "diff": "unified diff"}
]
}
```
Include `changes` with unified diffs for every file you modified. For analysis-only tasks, omit `changes` and focus on `analysis`.
## Tool Selection
| Goal | Tool |
|------|------|
| Exact symbol/string | `sg_keyword_search` |
| Concepts/semantic search | `sg_nls_search` |
| Trace usage/callers | `sg_find_references` |
| See implementation | `sg_go_to_definition` |
| Read full file | `sg_read_file` |
| Browse structure | `sg_list_files` |
| Find repos | `sg_list_repos` |
| Search commits | `sg_commit_search` |
| Track changes | `sg_diff_search` |
| Compare versions | `sg_compare_revisions` |
**Decision logic:**
1. Know the exact symbol? → `sg_keyword_search`
2. Know the concept, not the name? → `sg_nls_search`
3. Need definition of a symbol? → `sg_go_to_definition`
4. Need all callers/references? → `sg_find_references`
5. Need full file content? → `sg_read_file`
## Scoping (Always Do This)
```
repo:^github.com/ORG/REPO$ # Exact repo (preferred)
repo:github.com/ORG/ # All repos in org
file:.*\.ts$ # TypeScript only
file:src/api/ # Specific directory
```
Start narrow. Expand only if results are empty.
## Efficiency Rules
- Chain searches logically: search → read → references → definition
- Don't re-search for the same pattern; use results from prior calls
- Prefer `sg_keyword_search` over `sg_nls_search` when you have exact terms
- Read 2-3 related files before synthesising, rather than one at a time
- Don't read 20+ remote files without writing code — once you understand the pattern, start implementing
## If Stuck
If MCP search returns no results:
1. Broaden the search query (synonyms, partial identifiers)
2. Try `sg_nls_search` for semantic matching
3. Use `sg_list_files` to browse the directory structure
4. Use `sg_list_repos` to verify the repository name

# Chromium Renderer Process Sandbox Audit
## Your Task
Audit the security sandbox implementation for Chromium's renderer processes. Find all C++ source files in `chromium/chromium` that implement the sandbox: 1. The file under `sandbox/linux/seccomp-bpf-helpers/` that implements `BaselinePolicy` — the seccomp-BPF baseline policy for Linux sandboxing. 2. The file under `sandbox/win/src/` that implements `PolicyBase` — the Windows sandbox policy configuration (concrete implementation of `TargetPolicy`). 3. The file under `sandbox/policy/linux/` that implements `RendererProcessPolicy` — the BPF policy specific to renderer process sandboxing (look for `EvaluateSyscall`). 4. The file under `sandbox/policy/` that declares sandbox type utilities and the `SandboxType` enum mapping. Report each file path and key class/function.
## Context
You are working on a codebase task involving repos from the security domain.
## Available Resources
No local repositories are pre-checked out.
**Note:** Additional repositories are accessible via Sourcegraph MCP tools:
- `sg-evals/chromium--2d05e315` (chromium/chromium)
## Output Format
Create a file at `/workspace/answer.json` with your findings in the following structure:
```json
{
"files": [
{"repo": "org/repo-name", "path": "relative/path/to/file.go"}
],
"symbols": [
{"repo": "org/repo-name", "path": "relative/path/to/file.go", "symbol": "SymbolName"}
],
"chain": [
{"repo": "org/repo-name", "path": "relative/path/to/file.go", "symbol": "FunctionName"}
],
"text": "Narrative explanation of your findings, citing repos and file paths."
}
```
Include only the fields relevant to this task. Your answer is evaluated against a closed-world oracle — completeness matters.
## Evaluation
Your answer will be scored on:
- **File recall and precision**: Did you find all relevant files?
## COVERAGE REQUIREMENTS — Do Not Write answer.json Too Early
Before writing `answer.json`, you **must** verify coverage across all major
subsystems named in the task.
**Minimum workflow:**
1. **Enumerate** — Search for all relevant directories and files across the codebase.
2. **Read** — Read representative implementation files for each subsystem.
3. **Extract** — Extract the key symbols required by the task (not just file paths).
4. **Gap check** — List any providers, services, or middleware layers mentioned in
the task that are NOT yet backed by a concrete file read. If any gaps exist,
search for them before proceeding.
5. **Only then** write `answer.json`.
Do not stop after finding a plausible initial set of paths. The task rewards
**broad, complete coverage** of required files and symbols.
## PRE-TEST SANITY CHECK
Before running tests, perform this check:
1. List every file you have modified or created.
2. For each file, state in one sentence why it is necessary for the task.
3. If any file is unrelated to the stated task, **do not write it** (or revert
if already written).
Use MCP for discovery and confirmation. Use local repo state only for narrow
patching logic. Do not use `sg_read_file` output as a template to copy wholesale
into the workspace.

## Your Task
Audit the security sandbox implementation for Chromium's renderer processes. Find all C++ source files in `chromium/chromium` that implement the sandbox: 1. The file under `sandbox/linux/` that implements `BPFBasePolicy` — the seccomp-BPF base policy for Linux sandboxing. 2. The file under `sandbox/win/src/` that defines `TargetPolicy` — the Windows sandbox policy configuration. 3. The file under `content/browser/` that configures sandbox parameters for renderer process launch (look for `SetRendererSandboxPolicy` or `GetRendererSandboxType`). 4. The file under `sandbox/policy/` that defines `SandboxType` enum and sandbox profile mappings. Report each file path and key class/function.
## Context
You are working on a codebase task involving repos from the security domain.
## Available Resources
## Output Format
Use the published task contract:
- `TASK_WORKDIR=/workspace`
- `TASK_REPO_ROOT=/workspace`
- `TASK_OUTPUT=/workspace/answer.json`
Create a file at `TASK_OUTPUT` (`/workspace/answer.json`) with your findings in the following structure:
```json
{
"files": [
{"repo": "repo-name", "path": "relative/path/to/file.go"}
],
"symbols": [
{"repo": "repo-name", "path": "relative/path/to/file.go", "symbol": "SymbolName"}
],
"chain": [
{"repo": "repo-name", "path": "relative/path/to/file.go", "symbol": "FunctionName"}
],
"text": "Narrative explanation of your findings, citing repos and file paths."
}
```
Include only the fields relevant to this task. Your answer is evaluated against a closed-world oracle — completeness matters.
## Evaluation
Your answer will be scored on:
- **File recall and precision**: Did you find all relevant files?

| 30 | assistant | - | I've completed the sandbox audit. Here are the four components found in `chromium/chromium`: **1. seccomp-BPF base policy (Linux)** — `sandbox/policy/linux/bpf_base_policy_linux.cc`/`.h` - Class `BPFBasePolicy` (subclass of `bpf_dsl::Policy`). Its `EvaluateSyscall()` delegates to the underlying `BaselinePolicy` defined under `sandbox/linux/seccomp-bpf-helpers/baseline_policy.h`, which holds the actual seccomp baseline. **2. Windows sandbox policy (`TargetPolicy`)** — `sandbox/win/src/sandbox_policy.h` - `class TargetPolicy` (line 263) — the abstract interface (`SetTokenLevel`, `SetJobLevel`, `GetConfig`, …). The concrete implementation is `PolicyBase` in `sandbox_policy_base.h`. **3. Renderer launch sandbox config** — `content/browser/renderer_host/renderer_sandboxed_process_launcher_delegate.cc`/`.h` - `RendererSandboxedProcessLauncherDelegate::GetSandboxType()` returns `sandbox::mojom::Sandbox::kRenderer`; the Win subclass's `InitializeConfig()` applies renderer-specific policy at launch. **4. SandboxType enum + profile mappings** — `sandbox/policy/sandbox_type.h`/`.cc` (+ `sandbox/policy/mojom/sandbox.mojom`) - The enum itself is the mojom-generated `enum Sandbox` in `sandbox.mojom`. The mapping/helper functions (`IsUnsandboxedSandboxType`, `SetCommandLineFlagsForSandboxType`, `SandboxTypeFromCommandLine`, etc.) live in `sandbox_type.h/.cc`. One note worth flagging: the task description says the `SandboxType` enum is defined under `sandbox/policy/`, but in this checkout the enum is actually the mojom-generated `Sandbox` enum (in `sandbox/policy/mojom/sandbox.mojom`); `sandbox/policy/sandbox_type.h` only forward-declares it and supplies the profile-mapping functions. I included both files to cover the closed-world oracle. Results are written to `/workspace/answer... |
