Executing Plans Inline
obra/superpowers
Has the agent carry out an implementation plan itself, task by task in the current session, keeping a ledger, proving each step with a test and ending with one whole-branch review.

What it does
Start Here is an agent skill from fl-sean03/OpenSDL. Establish or resume an OpenSDL laboratory through a normal agent conversation. Use when a user says start here, set up or configure my lab, plan a new lab or cell, describe existing equipment, continue a lab build, or turn a laboratory idea into a simulator-first implementation plan.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Planning. The repository describes itself as: A modular Python foundation for reproducible computational and autonomous laboratories. Alpha; the reference profile is simulator-only. The licence is Apache-2.0.
When your agent uses it
- A user says start here
- Configure my lab
- Describe existing equipment
- Continue a lab build
Example prompts
- “/start-here”
Workflow steps
11 steps, taken from the first numbered list in SKILL.md.
- Read the nearest AGENTS.md. Inspect the worktree, branch, recent commits, and current directory
- Determine whether the user is in this framework repository, a generated laboratory repository,
- When a separate lab repository is needed, collect its name, owner, and destination. Use
- In a lab repository, read docs/lab/context.md, inventory.md, setup-plan.md, and
- Classify the setup as existing, greenfield, or hybrid. Identify the first outcome before trying
- Update the shared lab files with confirmed facts, evidence, assumptions, unknowns, constraints,
- Track inventory evidence, integration, and visual-twin state separately. An inventory entry is
- Map the first workflow to resources, typed capabilities, simulators, manual steps, data, tests,
- Update executable manifests or workflows only from confirmed information and supported
- Record any custom 3D request in the lab setup plan with its purpose, source evidence,
- Hand the next task to create-lab, orient-lab, design-lab, add-capability, add-adapter,
What it can do on your machine
Read from SKILL.md and the folder at commit 43f4988. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Start Here loads about 956 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 475 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Start or resume a laboratory
Inputs
- intended laboratory outcome or first useful workflow
- existing, planned, or hybrid setup
- repository or proposed destination
- known equipment, compute, manual work, samples, data, and locations
- relevant constraints, hazards, and available evidence
Begin with partial input. Ask for only the highest-value missing information.
Procedure
- Read the nearest
AGENTS.md. Inspect the worktree, branch, recent commits, and current directory before changing files. - Determine whether the user is in this framework repository, a generated laboratory repository, or an uninitialized destination.
- When a separate lab repository is needed, collect its name, owner, and destination. Use
create-labonly after the destination is confirmed and safe. - In a lab repository, read
docs/lab/context.md,inventory.md,setup-plan.md, anddecisions.mdwhen present. Then readopensdl.yamland only the workflows needed for the task. - Classify the setup as existing, greenfield, or hybrid. Identify the first outcome before trying to inventory the entire laboratory.
- Update the shared lab files with confirmed facts, evidence, assumptions, unknowns, constraints,
and decisions. Keep the product-wide work list in
docs/development/backlog.md. - Track inventory evidence, integration, and visual-twin state separately. An inventory entry is not authority to execute equipment.
- Map the first workflow to resources, typed capabilities, simulators, manual steps, data, tests, and gaps. Prefer one complete simulation path over a broad incomplete configuration.
- Update executable manifests or workflows only from confirmed information and supported
contracts. Run
opensdl validatefor any executable file changed. - Record any custom 3D request in the lab setup plan with its purpose, source evidence, dimensions, and target workflow. An agent can build the tailored Blender scene directly in the laboratory repository. OpenSDL currently has no dedicated digital-twin command and intentionally has no model catalog.
- Hand the next task to
create-lab,orient-lab,design-lab,add-capability,add-adapter,develop-workflow,add-domain-pack, ordebug-runas appropriate. Usedesign-labwhen the open question is physical or interface design rather than OpenSDL configuration.
Show full SKILL.md (158 more words)Show less
Do not run doctor, capability listing, inspection, or event queries merely for onboarding. They
read without writing and will not create a store that is not there, but they report operational
evidence rather than declared configuration, which is a different question from setting a
laboratory up. Never pass doctor --reconcile during onboarding: it releases the leases of running
runs and records their interrupted tasks as failed or as intervention_required depending on what
each capability declared, and nothing clears intervention_required.
Completion
The repository contains enough confirmed shared context for a fresh agent to continue. The first workflow has a capability and gap map. Any executable changes validate, and the next skill or future dependency is explicit.
Stop conditions
Stop before mutation when repository ownership or the destination is unclear. Stop when sources conflict, secrets or unintended facility details would enter Git, or a required typed operation is missing. Do not commission equipment or perform physical work through this skill.
