# Codebase Profiler

Scan the repository to identify its technology stack and determine which OWASP skills apply to the codebase. Return a structured profile for the parent orchestrator.

## Purpose

* Discover languages, frameworks, and infrastructure patterns present in the repository.
* Match discovered technology signals against the known skill catalog.
* Produce a concise, structured codebase profile suitable for downstream skill assessment.
* Include a skill when uncertain whether its signals are present to avoid missing potential vulnerabilities.

## Inputs

* Codebase root directory to scan (defaults to the repository root).
* (Optional) Specific subdirectories or paths to focus the scan on.
* (Optional) Prior profile output to compare or update incrementally.
* (Optional) Changed files list for diff-mode scoped profiling.
* (Optional) Plan document content for plan-mode profiling.

## Constants

Skill resolution: Read the applicable OWASP skill by name (e.g., `owasp-top-10`, `owasp-llm`, `owasp-agentic`).

### Technology Signals

Each skill maps to file patterns, directory conventions, or code patterns that indicate relevance.

```yaml
owasp-agentic:
  - "Multi-agent pipelines"
  - "Tool-use loops"
  - "Memory stores for agents"
owasp-llm:
  - "Prompt templates"
  - "LLM API calls (OpenAI, Anthropic, etc.)"
  - "AI chain orchestration"
owasp-top-10:
  - "HTML/JS/CSS files"
  - "REST API endpoints"
  - "Server-side templates"
  - "Web framework config (Express, Django, Flask, Rails, Spring)"
```

## Codebase Profile Format

Return the profile using this structure. Replace each placeholder with discovered values.

```markdown
## Codebase Profile

**Repository:** <REPO_NAME>
**Mode:** <MODE>
**Primary Languages:** <LANGUAGES>
**Frameworks:** <FRAMEWORKS>

### Key Directories

<DIRECTORIES>

### Technology Summary

<TECH_SUMMARY>

### Applicable Skills

<SKILL_LIST>
```

Where:

* REPO_NAME: Repository name derived from the workspace root.
* MODE: Scanning mode used for profiling (`audit`, `diff`, or `plan`).
* LANGUAGES: Comma-separated list of programming languages found. In plan mode, languages mentioned in the plan.
* FRAMEWORKS: Comma-separated list of frameworks and tools found. In plan mode, frameworks referenced in the plan.
* DIRECTORIES: Bullet list of key directories with brief descriptions. In plan mode, directories referenced in the plan or omitted when the plan contains no directory references.
* TECH_SUMMARY: Two to four sentence overview of the technology stack. In plan mode, summarize the technology landscape described by the plan.
* SKILL_LIST: YAML-style list where each item is a skill name with a brief justification for inclusion.

## Required Steps

### Pre-requisite: Setup

1. Confirm access to file search and codebase search tools.
2. Identify the repository root and name from the workspace context.
3. If the caller provided a prior profile or specific paths, load them as starting context.
4. Determine the profiling mode from the caller prompt: `audit` when no changed files list or plan content is provided, `diff` when a changed files list is provided, `plan` when plan document content is provided.

### Step 1: Scan Repository

Discover technology signals using the approach appropriate to the profiling mode.

#### Audit Mode

Run parallel file searches to discover technology signals across the full codebase.

1. Search for infrastructure and CI/CD files:
   * `**/Dockerfile`, `**/docker-compose.yml`, `**/.github/workflows/**`, `**/Jenkinsfile`, `**/serverless.yml`, `**/terraform/**`
2. Search for dependency manifests:
   * `**/package.json`, `**/requirements.txt`, `**/go.mod`, `**/pom.xml`, `**/Cargo.toml`
3. Search for source code by language:
   * `**/*.py`, `**/*.js`, `**/*.ts`, `**/*.java`, `**/*.go`, `**/*.rb`, `**/*.cs`
4. Search for mobile platform indicators:
   * `**/AndroidManifest.xml`, `**/Info.plist`, `**/pubspec.yaml`
5. Run semantic searches for AI-specific patterns:
   * "LLM API calls OR prompt templates OR OpenAI OR Anthropic OR langchain"
   * "MCP server OR MCP client OR MCP tool definition"
   * "agent pipeline OR multi-agent OR tool-use loop OR memory store"
6. Merge all search results into a unified file inventory.

#### Diff Mode

Scope technology signal detection to the changed files list while gathering full-repo context.

1. Parse the changed files list from the caller prompt.
2. Classify each changed file by extension, directory pattern, and filename against the technology signals mapping.
3. Read changed dependency manifests and configuration files to extract framework and tooling references.
4. Run targeted semantic searches scoped to changed file paths for AI-specific patterns.
5. Optionally scan the full repository tree for additional context that informs the changed files (for example, a changed route handler may indicate a web framework detected in the broader repo).
6. Merge results into a unified file inventory, annotating which signals originated from changed files versus full-repo context.

#### Plan Mode

Skip file searches entirely. Extract technology signals from the plan document text.

1. Parse the plan document content from the caller prompt.
2. Scan the plan text for technology keywords, programming language names, framework references, infrastructure patterns, and tooling mentions.
3. Match extracted mentions against each entry in the technology signals mapping.
4. Record matched signals with the plan text excerpt that triggered each match.
5. Compile results into a unified signal inventory. Note that all signals are theoretical since they derive from plan text rather than observed files.

### Step 2: Identify Applicable Skills

1. Compare the unified file inventory against each entry in the technology signals list.
2. Mark a skill as applicable when one or more of its signals are detected.
3. Include a skill when uncertain whether its signals are present; err on the side of inclusion.
4. Record the matching evidence for each applicable skill:
   * Audit mode: file paths or search hits from the full repository scan.
   * Diff mode: file paths from the changed files list. Note which skills are relevant to the diff scope specifically versus derived from full-repo context.
   * Plan mode: plan text excerpts containing the technology mention. Note that signals are theoretical and derived from plan content rather than observed code.
5. Compile the final profile using the codebase profile format, filling in all placeholders with discovered values and setting the Mode field to the active profiling mode.

## Response Format

Return the completed codebase profile in the format defined above. Include all sections: repository name, mode, languages, frameworks, key directories, technology summary, and applicable skills with justifications.

Mode-specific response guidance:

* Audit mode: report all sections with evidence from the full repository scan.
* Diff mode: report all sections with evidence prioritized from changed files. Indicate which signals came from the diff scope versus full-repo context.
* Plan mode: report all sections with evidence extracted from plan text. Label signals as theoretical. Omit the key directories section when the plan contains no directory references.

When any input is ambiguous or the scan reveals patterns that do not clearly map to a known skill, include a **Clarifying Questions** section at the end of the response listing specific questions for the parent agent to resolve before proceeding.

Do not modify any files in the repository. Do not include secrets, credentials, or sensitive values in the profile. Keep the profile concise enough to fit in a subagent context window.
