What is system-analysis?

A preparation skill for analyzing an accepted company model using systems-thinking methods. It gathers bounded information about workflows, states, measurements, decisions, constraints, evidence, and known gaps.

Use it before causal-loop or stock-flow analysis, Theory of Constraints, leverage-point analysis, TRIZ contradiction solving, or root-cause trees.

It prevents an analysis tool from guessing how the business works from unstructured prose or missing context.

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	$0.00035	$0.01232
Opus 5.5	$0.00014	$0.00493
Sonnet 5.5	$0.00007	$0.00246

Security

Grade A, and why

system-analysis 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 2mo 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.

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

System analysis projection

Use this skill before invoking a systems-thinking tool over the company model. It prepares the slice of accepted ontology that the tool needs and prevents the tool from guessing a system from loose prose.

When to use

Use when the user asks to analyze the company model with:

causal-loop or stock-flow thinking;
Theory of Constraints;
leverage-point analysis;
TRIZ contradiction solving;
why-tree/root-cause analysis.

Do not use this skill for standalone brainstorming that has no accepted ontology behind it.

Inputs

Read:

the accepted model slice relevant to the problem;
agent-os/SYSTEM_ANALYSIS.md;
specs/SYSTEM-ANALYSIS-SPEC.md;
source and evidence ids for the selected model slice;
open drift and unknowns that could affect the analysis.

Projection shape

Prepare a bounded projection with kind: systemAnalysisProjection. Use runtime.context_projection.build_system_analysis_projection when running inside this package, and validate the shape against schemas/system-analysis-projection.schema.json when possible.

The projection carries:

objective: measurable target or decision question;
analysisIntent: downstream analysis intent, such as constraint-finder, why-tree, triz, stock-flow, or leverage-finder;
modelIds: accepted objects, states, workflows, metrics, and decisions;
definitions: short accepted definitions with source ids;
workflow: participants, steps, transitions, exceptions, and metrics;
constraints: accepted bottlenecks, rules, policies, or source-of-truth limits;
delays: known waiting time, review time, handoff time, feedback delay;
metrics: formula, owner, source of truth, current value if available;
drift: open model-vs-reality gaps;
unknowns: missing fields that block the selected systems skill;
evidenceQuality: review risk, evidence mode, source adequacy, and SLA band;
competencyQuestions: questions this slice is supposed to answer;
sourceSummary: source ids, evidence ids, review package ids, and source event ids.

system-analysis is a skill published in the GitHub repository Vladick-Pick/business-ontology (3 stars, last pushed 3mo ago), licensed MIT. It adds 35 tokens to every session and 1,232 once invoked, about $0.0001 per session on Opus 5.5. 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.
