What is arch-lens-state-lifecycle?

A tool for drawing how application state changes, including field rules, validation checks, and safe resuming from saved progress.

Use it to document state lifecycles, mutation controls, validation gates, checkpoints, and resume detection.

It makes the rules that prevent invalid or corrupted state easier to inspect.

Token cost

What it costs to keep this loaded

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	$0.00034	$0.02653
Opus 5	$0.00017	$0.01326
Sonnet 5	$0.00007	$0.00531
Haiku 4.5	$0.00003	$0.00265

Security

Grade A, and why

arch-lens-state-lifecycle 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 309 lines — stays where its author put it; the contents beside it link to each section on GitHub.

State Lifecycle Architecture Lens

Cognitive Mode: Perspective (Quality Overlay) Primary Question: "How is state corruption prevented?" Focus: Field Contracts, Validation Gates, Resume Safety, State Mutation Control

When to Use

Need to understand state management architecture
Documenting field lifecycle contracts
Analyzing resume and checkpoint safety
User invokes /autoskillit:arch-lens-state-lifecycle or /autoskillit:make-arch-diag state

Critical Constraints

NEVER:

Modify any source code files
Show business logic details
Focus on data content (focus on mutation rules)
Run subagents in the background (run_in_background: true is prohibited)

ALWAYS:

Focus on STATE MUTATION RULES
Show field lifecycle categories
Document validation gates
Include resume detection strategy
BEFORE creating any diagram, LOAD the /autoskillit:mermaid skill using the Skill tool - this is MANDATORY
If the Skill tool cannot be used (disable-model-invocation) or refuses this invocation, do NOT proceed with diagram creation. Abort this step and omit the diagram from output.
After writing the diagram file, emit the absolute path as a structured output token as your final output. Resolve the relative temp/arch-lens-state-lifecycle/... save path to absolute by prepending the full CWD:
```
diagram_path = /absolute/cwd/temp/arch-lens-state-lifecycle/{filename}.md
```
This token is MANDATORY — the pipeline cannot proceed without it.

Arguments

/autoskillit:arch-lens-state-lifecycle [context_path]

context_path (optional) — Absolute path to a PR context file containing new files (★-prefixed) and modified files (●-prefixed) from the PR diff. When provided, read this file before beginning analysis and focus the diagram on the architectural areas affected by these specific files. When absent, explore the full CWD.

Analysis Workflow

Step 0: Read PR context (when provided)

If a context_path positional argument is present:

Read the file at context_path
Extract: new files list (★-prefixed), modified files list (●-prefixed)
Focus Step 1 exploration on the modules/components these files belong to
Apply ★ prefix on diagram nodes representing new files/components
Apply ● prefix on diagram nodes representing modified files/components

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.

arch-lens-state-lifecycle is a skill published in the GitHub repository TalonT-Org/AutoSkillit (5 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 2,653 once invoked, about $0.0002 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.
