How this analysis is made

Examples

Configuration location
Where is Stripe configured? I need to find the API keys and related settings.
Authentication flow
How does authentication work? Walk me through the login, session, and token verification process.
Infrastructure definitions
Where are the Kubernetes manifests for the API service? Show me the deployment, service, and ingress definitions.

Research

Research the codebase to find and explain specific topics. This is a read-only skill - it discovers and documents information but does not modify code.

When to Use

  • Understanding where something is configured (e.g., "Where is Stripe configured?")
  • Learning how a feature works (e.g., "How does authentication work?")
  • Finding implementation details (e.g., "Where are RSS feeds fetched and parsed?")
  • Locating infrastructure definitions (e.g., "Where are the Kubernetes manifests for the API?")
  • Mapping dependencies and data flows

Input

A research question about the codebase. Examples:

  • "Where is Stripe configured?"
  • "How does authentication work?"
  • "Where are RSS feeds fetched and parsed?"
  • "Where do we define Kubernetes manifests for the API service?"

If no question is provided, ask for clarification before proceeding.

Workflow

1. Interpret the Research Topic

Rewrite the question as a clear, concrete research goal:

  • "Where is Stripe configured?" → "Find where and how Stripe API keys are configured and used"
  • "How does authentication work?" → "Identify the main entry points for authentication and session handling"

If the topic is ambiguous, make a reasonable assumption and state it in the report.

2. Explore the Codebase

Use a top-down search strategy:

  1. High-level scan: Identify relevant directories and key modules
  2. Pattern matching: Use Glob and Grep to find likely matches by name, keywords, and patterns
  3. Deep reading: Read the most relevant files in detail

3. Build an Organized Understanding

Identify:

  • Which files, directories, and modules are involved
  • Main functions, types, or components that implement the feature
  • Related configuration (YAML, env, Terraform, Kubernetes, CI, etc.)
  • Important relationships:
    • Call chains or data flows
    • Entry points and public APIs
    • Integration with external services or other modules

4. Report Back Clearly

Produce a structured report including:

  • Topic: The research question answered
  • Locations: List of relevant paths (files/directories)
  • Summary: Short explanation for each location
  • Architecture notes: Key interactions or data flows
  • Follow-ups: Suggestions for next investigations

Output Format

Use the template at references/templates/research-findings.md for comprehensive reports.

For quick answers, use this minimal format:

## Research: [Topic]

### Locations
- `path/to/file` — [what it does]
- `path/to/dir/` — [what it contains]

### Summary
[How these pieces work together]

### Architecture Notes
[Key data flows or interactions]

### Follow-ups
- [Suggestion for next investigation]

Constraints

  • Read-only: Do NOT modify any files
  • No implementation: Do NOT create tests or code changes
  • Focused: Keep the report focused on the requested topic
  • High-value: Prefer insights over exhaustive file listings
  • Clear: Structure findings so a human can quickly follow

Example

Research Question: "How does authentication work?"

Research Goal: Identify the main entry points for authentication
and session handling.

Locations:
- `pkg/auth/handler.go` — HTTP handlers for login/logout/refresh
- `pkg/auth/jwt.go` — JWT token generation and validation
- `pkg/auth/middleware.go` — Authentication middleware for protected routes
- `pkg/auth/session/` — Session storage and management
- `config/auth.yaml` — Authentication configuration (token TTL, providers)

Summary:
Authentication uses JWT tokens with refresh token rotation. The
middleware validates tokens on protected routes and injects user
context. Sessions are stored in Redis with configurable TTL.

Architecture Notes:
- Login flow: handler.go → jwt.go (generate) → session/ (store)
- Request flow: middleware.go → jwt.go (validate) → inject user context
- Supports OAuth providers via config/auth.yaml

Follow-ups:
- Review token refresh logic for security
- Document the OAuth provider setup process
- Add integration tests for session expiration

Begin by interpreting the research question and planning the exploration strategy.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/codebase-research-mm8o51o5/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/codebase-research-mm8o51o5' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/codebase-research-mm8o51o5/download' --output '.skill-downloads/codebase-research-mm8o51o5/SKILL.md.part' && mv '.skill-downloads/codebase-research-mm8o51o5/SKILL.md.part' '.skill-downloads/codebase-research-mm8o51o5/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/codebase-research-mm8o51o5'

openskills read 'codebase-research-mm8o51o5'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/codebase-research-mm8o51o5/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
