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 | $0.00101 | $0.00756 |
| Opus 5 | $0.00051 | $0.00378 |
| Sonnet 5 | $0.00020 | $0.00151 |
| Haiku 4.5 | $0.00010 | $0.00076 |
Grade A, and why
state-check 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 9d 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.

What it actually says
State Check
Run a structured Operational State Check for a function or the full company.
Variables
function: sales | product | partnerships | tribe | research | company-wide context: [Brief situational context — what's happening that prompted this check?]
Instructions
Before running, read:
outputs/operations/workspace/31c-operational-state-model.md— Core operational states for each functionreference/state-check-guide.md— State Check format and four questionscontext/current-data.md— Current metrics and active workstreamscontext/pipeline.md— Active pipeline context
Run a structured State Check using the four questions from the State Check Guide:
1. Sea State (2 min) What external conditions have changed since last check? What's the environment doing?
2. Current State (3 min) What operational state is [function] actually in right now? Not what we want — what's true? Evidence: [list observable signals]
3. Heading Check (2 min) Are we on heading? Have we drifted? Assessment: [on heading / slight drift / significant drift]
4. Course Corrections (3 min) If drift detected: what specific, behavioral adjustments restore the state? Course corrections are behaviors, not goals. "Do X daily" not "achieve Y."
Output format:
Function: [name]
Current State: [one sentence assessment]
On Heading: Yes / Slight drift / Significant drift
Sea State Summary: [2-3 sentences]
Course Corrections: [bulleted list, max 3]
Next State Check: [recommended timing]
Total output: 1 page max. The point is clarity, not comprehensiveness.
What ships with it
1 file 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-check is a skill published in the GitHub repository mishahanin/heading-os (11 stars, last pushed 3d ago), licensed Apache-2.0. It adds 101 tokens to every session and 756 once invoked, about $0.0005 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 2026-09-03.
