Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00018 | $0.02441 |
| Opus 5 | $0.00009 | $0.01221 |
| Sonnet 5 | $0.00004 | $0.00488 |
| Haiku 4.5 | $0.00002 | $0.00244 |
Grade A, and why
history scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SourceAtlas: Smart Temporal Analysis (Git History)
Constitution: ANALYSIS_CONSTITUTION.md v1.0
Context
Analysis Scope: $ARGUMENTS (default: entire repository) Goal: Extract actionable insights from git history Time Limit: 5-10 minutes Prerequisite: code-maat (will ask permission to install if missing)
Quick Start
- Check cache (skip if
--forceflag present) - Check code-maat installation (install if needed with permission)
- Generate git log (last 12 months, code-maat compatible)
- Run analyses: Hotspots, Coupling, Contributors
- Risk assessment combining all dimensions
- Generate report following output-template.md
- Verify output using verification-guide.md
- Auto-save to
.sourceatlas/history.md
Your Task
You are analyzing git commit history to understand:
- Hotspots - Files changed most frequently (likely complex/risky)
- Temporal Coupling - Files that change together (hidden dependencies)
- Recent Contributors - Who has knowledge of which areas (bus factor)
- Risk Areas - Aggregate assessment for prioritization
What You'll Discover
| Analysis Type | Insight | Business Value |
|---|---|---|
| Hotspots | Complexity indicators | Refactoring priorities, technical debt |
| Coupling | Hidden dependencies | Architecture review targets |
| Contributors | Knowledge distribution | Bus factor risks, training needs |
| Risk | Aggregate assessment | Resource allocation decisions |
Core Workflow
Execute these steps in order. See workflow.md for complete details.
Step 0: Check Prerequisites (30 seconds)
Purpose: Ensure code-maat is installed and Java is available.
Check code-maat:
if [ -f "$HOME/.sourceatlas/bin/code-maat-1.0.4-standalone.jar" ]; then
export CODEMAAT_JAR="$HOME/.sourceatlas/bin/code-maat-1.0.4-standalone.jar"
fi
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

history is a skill published in the GitHub repository lis186/SourceAtlas (48 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 2,441 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
