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 | $0.00031 | $0.01881 |
| Opus 5 | $0.00015 | $0.00941 |
| Sonnet 5 | $0.00006 | $0.00376 |
| Haiku 4.5 | $0.00003 | $0.00188 |
Grade A, and why
state 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.
How it starts
The opening of the file, as written. The whole thing — 273 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Intent
Create a structured representation of the current state of a domain, system, or entity. This is the foundation for world modeling, enabling tracking of entities, relationships, and properties over time.
Success criteria:
- State captured in structured, queryable format
- Entities and relationships clearly identified
- Uncertainty and confidence explicitly represented
- Evidence anchors for all state assertions
Compatible schemas:
schemas/output_schema.yamlreference/world_state_schema.yaml
Inputs
| Parameter | Required | Type | Description |
|---|---|---|---|
scope |
Yes | string | What domain/system to model (e.g., "user authentication", "payment processing") |
schema |
No | object | State schema defining expected structure |
timestamp |
No | string | Point in time for state (default: now) |
depth |
No | string | Modeling depth: surface, detailed, comprehensive |
Procedure
-
Define scope boundaries: Clarify what is included in the state model
- Identify system or domain boundaries
- Determine entity types to include
- Establish relationship types to capture
-
Identify entities: Enumerate entities within scope
- Extract entity references from sources
- Assign unique identifiers
- Capture entity properties/attributes
-
Map relationships: Document connections between entities
- Identify relationship types (contains, depends_on, references)
- Note relationship directionality
- Capture relationship properties
-
Capture current values: Record current state of each entity
- Document property values with evidence
- Note uncertainty where values are unclear
- Record observation timestamp
-
Apply schema: Structure state according to schema if provided
- Validate against schema constraints
- Note schema violations or extensions needed
- Ensure required fields are populated
-
Ground state claims: Attach evidence to all assertions
- Reference source files, commands, or observations
- Note confidence level for each assertion
What ships with it
5 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.

state is a skill published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 4d ago), licensed Apache-2.0. It adds 31 tokens to every session and 1,881 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.
