What is light-orchestrator?

A coordinator for multi-stage research projects that stores the project’s official state in .light/passport.yaml and manages stages, checkpoints, handoffs, and recovery.

It helps start or resume projects, route work across stages 1–13, join parallel results, detect stale information, recover failures, and prepare handoffs.

It prevents research work from losing track of its current stage, failed checks, unfinished branches, or required user decisions.

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	$0.00141	$0.03824
Opus 5	$0.00071	$0.01912
Sonnet 5	$0.00028	$0.00765
Haiku 4.5	$0.00014	$0.00382

Security

Grade A, and why

light-orchestrator 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.

The scan reads SKILL.md. This mod also ships 9 executable files (resident/session_start_resident.py, scripts/decision_checkpoint.py, scripts/execution_mode.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 355 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Light orchestrator

Coordinate, route and recover the research lifecycle. Do not impersonate the stage skills and do not turn a deterministic check into a research judgment.

Read references/orchestrator-resource-map.md before a real lifecycle run. It defines intake, state authority, migration, evidence states, access tiers, resident budget and handoff. Read references/integration-contract.json when changing any role, gate or route. The detailed rationale is ../../docs/design/orchestrator-spec.md.

Non-negotiable boundaries

Never choose the research direction, final idea, plan, venue, back-edge, revision-budget exception, known-limitation conversion or final delivery for the user. Present a recommendation, evidence, alternatives and consequences, then stop.
reroute.py is advisory. Only passport.py add-back-edge --authorization-id <user-record> may write a real back-edge, and only after the user authorizes that exact route.
A back-edge must go to an earlier stage (to < from). The 2⊣3 data feasibility result is an admission_hold, not a back-edge.
Never call a gate passed from prose. Use a producer's light.findings.v1, run_checkpoint.py, its exit code, a fresh timestamp and a content hash.
Never collapse evidence states. Use only VERIFIED, PLANNED, UNKNOWN, UNAVAILABLE or FAILED.
Never overwrite dirty/untracked user work, silently migrate a passport, silently rerun a stale downstream chain, or silently mark a limitation.
Never put an overlay or engineering skill in the scientific DAG. system-design, frontend-design, patent-disclosure and software-copyright have no stage, findings, STAGE_GATES, ROUTES or scientific back-edge.
Never claim 23-skill delivery because files exist. Verify the live inventory, hashes, checkpoints, limitations, handoff and user delivery decision.
Never silently install or reconfigure local runtimes. If a stage emits an environment advisory such as r_advisory.requires_user_choice=true, present the choices and consequences; only continue with install/config after an explicit user authorization. Non-interactive runs may choose the documented honest fallback only when the downstream contract does not require that runtime.

Changes

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.
