Long Long Run
Use this skill when the work is not a short edit-and-exit task. Typical triggers:
- long-running training, tuning, evaluation, or monitoring
- project takeover, archaeology, recovery, or external-drive exploration
- tasks where one main objective must stay coherent across many turns
What this skill is
long-long-run is a code-first, agent-owned evidence-chain harness.
It is not a questionnaire and it is not a giant state form.
It is not a project management system or evidence archive.
The runtime owns:
- session binding
- mode semantics
- authorization to start implementation
- current evidence-chain context
- progress checkpoints
- hook context and stop behavior
The agent should mainly control it through Python or a very small CLI surface.
Runtime requirement
The runtime scripts require python3.
They use only the Python standard library and do not require third-party packages.
Modes
The runtime has exactly three modes:
inc
INC means Intent Noise Cancellation.
This is the default mode.
INC is for reducing uncertainty, clarifying the contract, and converging on the current best understanding of the work.
INC is not limited to passive analysis or conversational planning.
The agent should use judgment and take the actions needed to build or revise the evidence chain, make the work more legible, test assumptions, and clarify the contract, unless the user narrows that scope.
INC may be used as a standalone exploration or decision-support mode.
It does not have to lead to ACTIVE.
INC may inspect files, run commands, create probes, or make bounded changes when that is the right way to obtain evidence.
For substantive INC work, read references/inc-best-practices.md before synthesizing expert defaults, evidence-chain gaps, or the next INC move unless you have already read it in this session.
This especially applies when the user goal is unclear, the domain framing matters, acceptance criteria must be inferred, or the work may remain INC-only.
The distinction is semantic, not mechanical.
INC is allowed to stay live for the whole session.
INC does not have a stop guard.
INC does not grant implicit authorization to treat the work as the committed mainline.
active
ACTIVE means the user has explicitly chosen to let the agent carry the agreed direction as the mainline.
ACTIVE is not defined by a different tool set.
It is defined by commitment and ownership: the work is now being pursued as the authorized implementation and delivery track.
ACTIVE means authorized continuation until the objective is complete, blocked, stopped by the user, or changed enough to require INC.
ACTIVE has the stop guard.
disabled
There is no live long-long-run objective for the session.
The core rule
Readiness is not authorization.
Capability is not commitment.
The agent may be fully ready in INC and still remain in INC.
The agent may act in INC without that implying a transition to ACTIVE.
The user decides whether to enter ACTIVE.
The agent decides whether and when it is appropriate to raise that transition.
The runtime may enter ACTIVE only after explicit user authorization.
If new evidence shows that the authorized mainline needs a material change, return to INC or ask the user for confirmation instead of silently expanding the contract.
Expert defaults must be visible
In INC, the agent should act like a domain expert.
That means:
- propose strong default constraints
- propose quality standards and guardrails
- search when those standards are uncertain
Before presenting expert defaults, the agent should ask whether the domain needs calibration.
If current practice, ecosystem changes, standards, tools, versions, safety, policy, design conventions, or industry norms may affect the answer, perform a bounded domain calibration pass.
This pass should run discovery before validation: start from the user's wording and project vocabulary, discover domain terms and quality bars, then use focused searches to validate hypotheses.
It should not start from remembered solution terms unless the user or project evidence already points there.
If external calibration is skipped, the agent should make the reason visible.
But those defaults must not stay implicit.
The agent should surface them clearly so the user can:
- accept them
- adjust them
- reject them
INC must not feel like a black box.
Default quality posture
Ambiguity does not imply demo.
Unless the user explicitly asks for a demo, prototype, spike, POC, or other disposable artifact, the default delivery posture is:
Runtime shape
State is intentionally small.
The runtime keeps only:
runtimecontractthinkingactivationprogress
Do not try to store every thought.
Only store current durable truth that changes runtime behavior.
thinking is a working model, not private chain-of-thought.
thinking.evidence_chain should contain only current effective evidence.
If evidence is overturned, remove or replace it in evidence_chain; record the major change as a short checkpoint if the history matters.
progress.completion_signal records what evidence would make the agent judge the current objective complete enough to stop.
progress.closure records whether the current long-running objective is open or closed.
The stop guard helps prevent premature stopping in ACTIVE.
It prevents stopping merely because a local step produced a useful update while the authorized mainline still has a clear, contract-covered next step.
Legacy states
This runtime does not auto-migrate old long-long-run JSON.
If an older schema is found, normal runtime operations should surface a repair requirement.
Repair is required before relying on LLR state.
It does not have to happen before answering an unrelated user message.
When repair is needed, the agent should:
- read the old JSON explicitly
- infer the still-valid objective, contract, and progress
- rebuild the state in the current schema through the new runtime API

Prefer Python over large JSON patch commands.

CLI usage
Use the CLI when a direct script call is simpler than a Python snippet.
python3 "$LLR_CTL" current \
--auto-create \
--project-root /path/to/project
python3 "$LLR_CTL" checkpoint \
--summary "Finished the first project scan." \
--next-action "Read the backend entrypoints."
python3 "$LLR_CTL" authorize-active \
--evidence "The user explicitly said: start implementation now."
python3 "$LLR_CTL" activate
python3 "$LLR_PY/test_runtime.py"
