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 | $0.00090 | $0.00388 |
| Opus 5 | $0.00045 | $0.00194 |
| Sonnet 5 | $0.00018 | $0.00078 |
| Haiku 4.5 | $0.00009 | $0.00039 |
Grade A, and why
constellation-start 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 8d 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
Start the Constellation live board
Brings the WS server + local bridge online. Use when:
- Setting up Constellation for a new project (first-time start)
- Restarting after a crash or operator-initiated stop
- Verifying the board is reachable from the current host
Steps
- Check
state.jsonexists (<project>/.constellation/state.jsonor<project>/dashboard/live/state.json). If absent, initialise from the schema inconstellation/reference/state-schema.md. - Spawn
node constellation/reference/runtime/server.cjson the configured port (default:7878). - Spawn
node constellation/reference/runtime/local-bridge.cjs(file-IO control bridge for turn-based agents). - Verify both processes are alive (the §13.16.4 HELLO churn dampening should NOT fire on cold start; if it does, indicates a stale lock).
- Print the dashboard URL (
http://localhost:7878/) for the operator. - (Optional) Spawn the watchdog (
node constellation/reference/runtime/watchdog.eux-equivalent) for server/bridge liveness monitoring.
Stop sequence
Use /constellation-stop to graceful-shutdown both processes (HELLO churn dampening + reconnect-friendly close).
Spec source
Constellation.md §6 (reference implementation) + §4 (runtime patterns).
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.

constellation-start is a skill published in the GitHub repository SoliEstre/EstreGenesis (8 stars, last pushed 2d ago), licensed Apache-2.0. It adds 90 tokens to every session and 388 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 2026-08-31.
