sourcecode 1.27.0

Deterministic codebase context for AI coding agents

sourcecode

Compressed AI-ready context for Java/Spring enterprise codebases.

---

What is it?

sourcecode analyzes a repository and produces structured JSON or YAML designed to be fed directly to AI agents or language models. It solves the "stuff the whole repo into the prompt" problem by extracting a deterministic, high-signal summary: stack detection, entry points, dependencies, git hotspots, inline annotations, and confidence metadata.

Optimized for Java/Spring Boot monorepos. Works on any codebase.

Quickstart

# High-signal summary (1000–3000 tokens depending on repo size) — recommended starting point
sourcecode --compact

# Add git hotspots and uncommitted file count
sourcecode --compact --git-context

# Analyze a specific path
sourcecode /path/to/repo --compact

# Copy result to clipboard
sourcecode --compact --copy

# Structured output for AI agents (identity, entry points, dependencies, confidence)
sourcecode --agent

# Only process git-modified files (forces compact output)
sourcecode --changed-only

Example output for a Spring Boot project (--compact):

  "stacks": [{ "stack": "java", "detection_method": "manifest", "confidence": "high",
               "primary": true, "frameworks": ["Spring Boot", "MyBatis"] }],

Flags reference

Flag	Alias	Default	Description
--compact		off	High-signal summary (1000–3000 tokens): stacks, entry points, dependencies, risk flags, confidence, gaps. Includes security_surface, mybatis, and transactional_boundaries for Java projects.
--agent		off	Structured noise-free JSON for AI agents: identity, entry points, dependencies, confidence, gaps. Auto-enables dependency, env-var, and code-notes analysis.
--full		off	Remove truncation limits on transactional_boundaries, mybatis.dto_mappers, and other capped lists.
--git-context	-g	off	Include git activity: recent commits, change hotspots, and uncommitted changes.
--changed-only		off	Limit output to git-modified files (staged, unstaged, untracked). Forces compact output.
--depth		4	File tree traversal depth (1–20). Java/Maven projects auto-adjust to 12.
--format	-f	json	Output format: json or yaml.
--output	-o	stdout	Write output to a file instead of stdout.
--copy	-c	off	Copy output to clipboard after a successful run. No-op when --output is set or clipboard is unavailable.
--no-redact		off	Disable automatic secret redaction. Output may contain sensitive values.
--version	-v	—	Show version and exit.

prepare-context — task-specific context

Generates a focused context bundle for a specific AI coding task. More targeted than --compact: each task re-ranks files according to its own signal priorities.

sourcecode prepare-context TASK [PATH] [OPTIONS]

Tasks

Task	What it surfaces	Primary use
explain	Architecture, entry points, key dependencies	Onboarding an LLM to a new project
onboard	Full structural context: entry points, architecture, key files, dependencies	New developer or agent joining the codebase
fix-bug	Files ranked by risk (annotations, churn, uncommitted changes), suspected areas	Debugging session
refactor	Structural problems, improvement opportunities, high-annotation files	Code quality review
generate-tests	Source files without test pairs, coverage gap analysis	Writing missing tests
review-pr	Uncommitted/changed files + architectural impact	Pre-merge review
delta	Changed files with multi-hop impact analysis, structural import graph, system-level impact summary	Incremental CI/review context

Options

Option	Description
--since REF	Git ref for delta task (e.g. HEAD~3, main, v1.2.0). Required for delta; ignored for other tasks.
--symptom TEXT	(fix-bug only) Keyword hint for the bug — boosts matching files and surfaces related code notes.
--llm-prompt	Append a ready-to-use LLM prompt to the output.
--dry-run	Show what would be analyzed without running it.
--copy / -c	Copy output to clipboard after a successful run.
--output / -o	Write output to a file.
--task-help	List all tasks with descriptions and exit.

Examples

# Explain the current repo
sourcecode prepare-context explain

# Focus on bug-prone files, with a symptom hint
sourcecode prepare-context fix-bug --symptom "NullPointerException in OrderService"

# Incremental context: files changed since branch diverged from main
sourcecode prepare-context delta . --since main

# Onboard with a ready-to-paste LLM prompt
sourcecode prepare-context onboard --llm-prompt

# List all tasks
sourcecode prepare-context --task-help

delta — incremental impact analysis

The delta task is the recommended mode for CI pipelines and PR reviews. It goes beyond listing changed files: it builds a structural import graph and propagates impact transitively up to 3 hops.

sourcecode prepare-context delta [PATH] --since REF

Output fields:

Field	Description
changed_files	Files modified in the git range
relevant_files	Changed files + files pulled in by the import graph (scored by artifact type and hop distance)
impact_summary	Human-readable summary: artifact types changed and active risk areas
affected_modules	DDD domain modules touched by the change
risk_areas	Per-area severity breakdown (security, api, persistence, etc.)
change_type	Closed taxonomy: behavioral_change, structural_change, configuration_change, dependency_change, security_change
system_impact	Subsystems affected, behavioral changes, runtime impact notes
dependency_graph_summary	Verified structural import edges (hop 1–3) and propagation_depth. Only real imports — no heuristics, no test files.
impact_score_per_file	Per-file numeric impact score (0–1)
since	The git ref used
gaps	What the analysis could not determine

How the import graph works:

1. Each changed file is classified by artifact type (controller, service, repository, security, spring_config, etc.).
2. A BFS traversal walks the import graph repo-wide (not restricted to the same module), up to 3 hops deep.
3. dependency_graph_summary.edges only contains verified import / @Autowired / constructor-injection relationships. Test files and heuristic proximity matches are excluded from edges (they appear in relevant_files only if they have real imports of changed files).
4. Score decays 30% per hop: a directly-changed SecurityConfig.java scores 0.90; its direct importer scores 0.63; a transitive importer scores 0.44.

# Changed service → controller → facade (3 hops)
sourcecode prepare-context delta . --since main

# Output includes:
# dependency_graph_summary.edges:
#   hop-1: OrderService.java → OrderRepository.java
#   hop-2: OrderRepository.java → OrderController.java
#   hop-3: OrderController.java → OrderFacade.java
# propagation_depth: 3

Output schema

All outputs include a confidence_summary block with overall, stack, and entry_points confidence levels (high / medium / low), plus an analysis_gaps list describing what could not be analyzed and why.

Java/Spring-specific fields

When a Java manifest (pom.xml or build.gradle) is detected, the output includes additional fields:

Field	Description
language_version	Java version from maven.compiler.source or equivalent
deployment.spring_boot_version	Spring Boot version
deployment.packaging	jar or war
deployment.app_server_hint	weblogic, wildfly, etc. (when detectable)
security_surface.resource_names	Values of @M3FiltroSeguridad(nombreRecurso=...) annotations across all controllers
mybatis	Mapper interface / XML file pairing summary
transactional_boundaries	Classes annotated with @Transactional
deployment_risks	Static risk flags: spring-boot-2.x-eol, legacy-java-runtime, legacy-app-server-deployment

Telemetry

Anonymous, opt-in telemetry collects: version, OS, commands used, flags, duration, repo size range, and errors. No source code, paths, secrets, or output content is ever collected.

sourcecode telemetry status    # current setting
sourcecode telemetry enable    # opt in
sourcecode telemetry disable   # opt out (permanent)

Alternatively, set the environment variable:

export SOURCECODE_TELEMETRY=0

Configuration

sourcecode config    # show version, config file path, telemetry status
