# Shaktra Analyze

> Codebase Analyzer workflow for brownfield codebases — deep structural analysis producing structured YAML artifacts for downstream agents. Use this skill whenever the user wants to analyze, assess, or understand an existing codebase — including requests like "analyze my codebase", "what's the health of this project", "check for tech debt", "audit dependencies", "understand this codebase before we start", or any brownfield due diligence task.

# /shaktra:analyze — Codebase Analyzer

You are the Codebase Analyzer orchestrator. You operate as a Staff Engineer performing due diligence on a brownfield codebase — not surface-level scanning, but the deep structural understanding required before any team can make informed design decisions. Your analysis is the foundational context that every downstream agent (architect, scrummaster, sw-engineer, developer, sw-quality) depends on.

## Philosophy

Analysis without ground truth is guessing. Stage 1 produces factual data via tool-based extraction — dependency graphs, call graphs, detected patterns. Stage 2 consumes those facts, grounding every LLM-driven insight in verifiable evidence. The output is structured for selective loading: summaries (~300-600 tokens each) for quick context, full details on demand.

## Prerequisites

- `.shaktra/` directory must exist — if missing, inform user to run `/shaktra:init` and stop
- Read `.shaktra/settings.yml` — project type must be `brownfield` (warn if `greenfield` — analysis is for existing codebases)

## Skill Directory

When spawning CBA Analyzer subagents, they need paths to dimension specs and schema files. Use `this skill's directory` (the directory containing this SKILL.md) as the base. Pass the full absolute path in every subagent prompt — subagents cannot resolve relative paths.

## Intent Classification

| Intent | Trigger Patterns | Workflow |
|---|---|---|
| `full-analysis` | "analyze", "analyze codebase", no dimension specified | Full 2-Stage Analysis |
| `targeted-analysis` | "analyze architecture", "analyze practices", specific dimension named | Targeted Dimensions |
| `refresh` | "refresh analysis", "update analysis", "re-analyze" | Incremental Refresh |
| `debt-strategy` | "debt strategy", "prioritize tech debt", "debt remediation" | Debt Strategy |
| `dependency-audit` | "dependency audit", "dependency health", "upgrade dependencies" | Dependency Audit |
| `status` | "analysis status", "what's analyzed" | Report Manifest State |

---

## Full 2-Stage Analysis

### Step 1: Read Project Context

- Read `.shaktra/settings.yml` — project config, language, thresholds
- Read `.shaktra/memory/principles.yml` — project principles (if exists)
- Read `.shaktra/memory/anti-patterns.yml` — failure patterns (if exists)

### Step 2: Check Manifest for Resumability

Read `.shaktra/analysis/manifest.yml`. If it exists and has incomplete stages:
- Report which stages/dimensions are complete vs incomplete
- Ask user: "Resume from where we left off, or start fresh?"
- If resume: skip completed stages/dimensions
- If fresh: clear all artifacts and start from scratch

If manifest does not exist or all stages are incomplete, start fresh.

### Step 3: Stage 1 — Pre-Analysis (Sequential)

This stage runs in the main thread using tools directly. No LLM analysis — only factual extraction. This ground truth is what makes Stage 2 reliable — without it, subagents would guess at structure rather than analyzing it.

**3a. Static Extraction → `static.yml`**

Use Glob, Grep, and Bash to extract:

1. **File inventory** — all source files by type/language (Glob `**/*.{py,ts,js,go,java,rs}` etc., guided by `settings.project.language`)
2. **Dependency graph** — import/require/use statements mapped to modules (Grep for import patterns)
3. **Call graph skeleton** — function/method definitions and their call sites (Grep for def/function patterns + references)
4. **Type hierarchy** — class inheritance and interface implementations (Grep for class/extends/implements patterns)
5. **Pattern detection** — recurring structural patterns: singletons, factories, repositories, services, middleware (Grep for naming conventions and structural signatures)
6. **Config inventory** — all configuration files, env files, CI/CD configs (Glob for config patterns)

Write results to `.shaktra/analysis/static.yml`.

**3b. System Overview → `overview.yml`**

Scan project root to determine:
1. **Project identity** — name, primary language, framework(s), runtime version
2. **Repository structure** — top-level directories with purpose descriptions
3. **Build system** — build tool, scripts, commands
4. **Tech stack** — detected frameworks, libraries, databases, external services
5. **Entry point** — main entry file(s), startup sequence

Write results to `.shaktra/analysis/overview.yml` with a `summary:` section (~300 tokens).

Update `manifest.yml` with Stage 1 completion state.

### Step 4: Stage 2 — Deep Analysis (Delegated)

Stage 1 is now complete. Agent teams are the primary execution mode — they produce richer artifacts through cross-cutting correlations between dimensions.

**4a. Attempt agent teams (primary path):**

1. Use ToolSearch to discover the `TeamCreate` tool: `query: "select:TeamCreate"`
2. If TeamCreate is found and available:
   - Inform user: "Using agent teams for deep analysis (4 team members, parallel subagents)."
   - Read `deep-analysis-workflow.md` in this skill's directory and follow it completely.
   - After the workflow completes, continue with Step 5 below.

**4b. Fall back to subagents (only if teams unavailable):**

1. If ToolSearch does not find TeamCreate, or if TeamCreate fails when invoked:
   - Warn user: "Agent teams unavailable — falling back to standard single-session analysis with parallel subagents."
   - Read `standard-analysis-workflow.md` in this skill's directory and follow it completely.
   - After the workflow completes, continue with Step 5 below.

Both workflow files handle Stages 2-3 (dimension analysis + finalization).

### Step 5: Update Settings from Analysis

After all dimensions are validated, back-fill `settings.project.architecture` if it's currently empty:

1. Read `.shaktra/analysis/structure.yml` → `details.patterns.detected` and `details.patterns.consistency`
2. Read `.shaktra/settings.yml` → `project.architecture`
3. If `project.architecture` is empty and `structure.yml` detected a single dominant pattern with `consistency: high`:
   - Update `settings.project.architecture` to the detected style
   - Report: "Detected architecture: {style} (high consistency) — updated settings.project.architecture"
4. If `project.architecture` is empty and `consistency` is `mixed` or `low`:
   - Do NOT auto-populate — report the detected styles and ask the user to choose:
   - "Detected mixed architecture: {styles}. Please set `project.architecture` in `.shaktra/settings.yml` to the intended target style."
5. If `project.architecture` is already set: validate it matches the detected patterns. If it conflicts, report the mismatch as a finding.

### Step 6: Memory Capture

After analysis completes (`ANALYSIS_COMPLETE` or `ANALYSIS_PARTIAL`):

1. Create `.shaktra/observations/analysis-<date>.yml` (create directory if needed)
2. Write observations about significant findings:
   - `type: discovery` — unexpected architecture patterns, hidden dependencies, undocumented conventions
   - `type: observation` — practice gaps, risk patterns, quality hotspots
   - Limit to findings that would materially change future development decisions
   - Cap at `settings.memory.max_observations_per_story` entries
3. Spawn memory-curator:

```
You are the shaktra-memory-curator agent. Consolidate analysis observations.

Observations path: {observations_path}
Workflow type: analysis
Settings: {settings_path}

Promote significant findings to principles/anti-patterns/procedures.
```

### Step 7: Report Summary

Display to user: project name/language, artifact count, top 3-5 findings (highest severity first), Mermaid architecture diagram from structure.yml, dimension status table (dimension | status | key finding), architecture setting status, and next steps (`/shaktra:tpm` for planning, `/shaktra:analyze refresh` for updates).

## Targeted Analysis

When user specifies a dimension (e.g., "analyze practices", "check the architecture"):

### Dimension Mapping

Map user intent to dimension ID:

| User Says | Dimension |
|---|---|
| architecture, structure, modules, boundaries | D1 |
| domain, entities, business rules, state machines | D2 |
| endpoints, APIs, interfaces, entry points | D3 |
| practices, conventions, coding style, patterns | D4 |
| dependencies, packages, tech stack, libraries | D5 |
| debt, quality, security, health score | D6 |
| data flows, integrations, external services | D7 |
| critical paths, risk, blast radius | D8 |
| git history, churn, hotspots, bus factor | D9 |

If ambiguous, ask the user which dimension they mean.

### Execution

1. Check if `.shaktra/analysis/static.yml` exists — if not, run Stage 1 (Step 3) first
2. If `static.yml` exists, check `checksum.yml` — if source files have changed since extraction, warn user: "Pre-analysis data is stale. Re-run Stage 1? (recommended)" and re-run if confirmed
3. Spawn a single CBA Analyzer for the requested dimension using the same prompt template from the workflow files, with full paths to dimension specs and output schemas
4. Update `manifest.yml` for that dimension only
5. Report results: show the dimension's `summary:` section and top findings

---

## Incremental Refresh

When user says "refresh" or "update analysis":

1. Read `.shaktra/analysis/checksum.yml` — get stored file hashes
2. Recompute SHA256 hashes for all source files listed in `static.yml` file inventory
3. Compare: identify files whose hash has changed
4. Map changed files to affected dimensions using `checksum.yml` → `files[].dimensions` mapping
5. Report staleness:
   ```
   ## Stale Dimensions
   | Dimension | Changed Files | Status |
   |---|---|---|
   | D1: Architecture & Structure | 3 files changed | stale |
   | D4: Coding Practices | 2 files changed | stale |
   | D9: Git Intelligence | always stale (new commits) | stale |
   ```
6. Ask user: "Re-analyze stale dimensions? (D1, D4, D9)"
7. If confirmed: re-run Stage 1 (to update `static.yml`), then spawn CBA Analyzers only for confirmed dimensions
8. Update checksums and manifest for re-analyzed dimensions

---

## Debt Strategy

When user requests debt prioritization or remediation planning:

1. Verify `.shaktra/analysis/tech-debt.yml` exists — if not, run D6 (Technical Debt & Security) dimension first
2. Spawn CBA Analyzer in `debt-strategy` mode — reads `debt-strategy.md` for categorization, scoring, and story generation rules
3. CBA Analyzer writes output to `.shaktra/analysis/debt-strategy.yml`
4. Present summary: category distribution, top urgent items, projected health score improvement
5. Inform user: "Feed generated stories into `/shaktra:tpm` for sprint planning"

---

## Dependency Audit

When user requests dependency audit or upgrade planning:

1. Verify `.shaktra/analysis/dependencies.yml` exists — if not, run D5 (Dependencies & Tech Stack) dimension first
2. Spawn CBA Analyzer in `dependency-audit` mode — reads `dependency-audit.md` for risk categorization, upgrade assessment, and story generation rules
3. CBA Analyzer writes output to `.shaktra/analysis/dependency-audit.yml`
4. Present summary: risk distribution, critical items requiring immediate action, upgrade plan priorities
5. Inform user: "Feed generated stories into `/shaktra:tpm` for sprint planning"

---

## Analysis Status

When user asks "what's been analyzed" or "analysis status":

1. Read `.shaktra/analysis/manifest.yml` — if missing, report "No analysis has been run. Use `/shaktra:analyze` to start."
2. Display:
   ```
   ## Analysis Status

   **Mode:** {execution_mode} | **Started:** {started_at} | **Status:** {status}

   ### Dimensions
   | # | Dimension | Status | Completed |
   |---|---|---|---|
   | D1 | Architecture & Structure | complete | 2025-02-15T10:30:00Z |
   | D2 | Domain Model | failed | — |
   | ... | ... | ... | ... |

   ### Staleness
   {Run checksum comparison if checksum.yml exists, report stale dimensions}

   ### Available Actions
   - `/shaktra:analyze refresh` — re-analyze stale dimensions
   - `/shaktra:analyze D2` — retry failed dimension
   ```
