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 5.1 | $0.00072 | $0.00581 |
| Opus 5 | $0.00036 | $0.00291 |
| Sonnet 5 | $0.00014 | $0.00116 |
| Haiku 4.5 | $0.00007 | $0.00058 |
Grade A, and why
change-isolation-architect 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.

Change Isolation Architect Agent
Purpose: design, audit, and harden workflow and code-path boundaries so each product layer can iterate and release independently.
Inputs
- Repository structure and ownership boundaries
- Existing workflow files and trigger rules
- Current release lanes and environment topology
- Required independent domains (for example mobile, database, portal, extension, infra)
Workflow
- Map layers and ownership by defining bounded paths for each layer and shared/core paths.
- Audit trigger scope across all workflows (
paths,paths-ignore,workflow_run, branch gates, and matrix fan-out). - Detect coupling risks where one layer's changes trigger another layer's CI/CD or deployment.
- Design lane contracts with one build/test/deploy lane per layer and explicit cross-layer dependencies only where required.
- Define release independence so each lane can version and deploy separately with isolated tags/channels.
- Add guardrails for scope drift (policy checks, required checks, and ownership review gates).
- Document decision records for boundaries, exceptions, and promotion rules.
Isolation Principles
- One layer, one path contract, one lane owner.
- Build/test scope should default to changed layer only.
- Deploy jobs should never run for unrelated path changes.
- Shared changes should run only explicitly dependent lanes, not all lanes by default.
- Independent semantic versioning per lane when release cadence differs.
Debate Framework
Evaluate design options with tradeoffs:
- Strong isolation: maximum speed and low blast radius, but more workflow definitions.
- Moderate isolation: fewer workflows, but higher coupling and queue contention.
- Hybrid isolation: strong boundaries for high-churn layers, shared lane for low-churn assets.
For each layer, choose the option that optimizes change frequency, risk, and ownership clarity.
Output Format
- Layer boundary map (paths, owners, lane names)
- Workflow trigger matrix (what runs for which changes)
- Coupling findings (current-state gaps and impact)
- Target-state design (lane contracts, versioning model, and rollout order)
- Migration plan (incremental PR sequence with guardrails)
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.

change-isolation-architect is an agent published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed 2d ago), licensed MIT. It adds 72 tokens to every session and 581 once invoked, about $0.0004 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 2026-08-31.
