What it does

Lane is an agent skill from lukeed/lane. Use lane in this repository — create isolated worktrees, read existing context before editing, and record constraints that future work must preserve.

Its SKILL.md is about 930 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 Development, covering Git worktrees. The repository describes itself as: Copy-on-write worktrees with memory that survives them. The licence is MIT.

When your agent uses it

  • Tasks that involve Git worktrees

Example prompts

  • “/lane”

What it can do on your machine

Read from SKILL.md and the folder at commit 4235dd7. 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 (its code samples are bash).

    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

Lane loads about 928 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 407 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~928

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.

description
Use lane in this repository — create isolated worktrees, read existing context before editing, and record constraints that future work must preserve.

lane

This repository keeps durable context / memories as Markdown under .lane/. You must read before editing a file, via lane why <path>, then record only the non-obvious constraints or decisions another agent would otherwise have to rediscover.

Workflow

bash
lane new fix-login     # create a branch and worktree
# edit and commit as usual
lane merge             # land on local trunk
lane merge --squash    # land on local trunk as one commit
lane push              # push the lane for a pull request

lane new prints the worktree path. Work there, not in the parent checkout.

lane merge rebases, audits memory, updates local trunk, and removes the lane. Commit or stash tracked changes first.

The push workflow is for protected trunks. After the pull request merges, run lane prune. Use lane ls --json for machine-readable lane state.

Read before editing

bash
lane why src/auth.rs
lane why src/

Run lane why for every file you intend to edit. A directory returns all notes beneath it; --json includes full ids, anchors, timestamps, and note text.

Run lane check before landing. For every stale note, take exactly one action:

bash
lane note confirm <id>              # the note is still true
lane note replace <id> "<rewrite>"  # the constraint has changed
lane note retire <id>               # the constraint no longer applies

An unambiguous id prefix is enough. Use lane note edit <id> for the interactive menu, or the direct commands above in scripts and agent workflows.

Other lifecycle commands:

bash
lane note restore <id>  # restore a retired note
lane note pin <id>      # protect a note from eviction
lane note unpin <id>    # remove that protection

Record what must stay true

Not every file or commit needs a note. Only record significant, non-obvious constraints — never a summary of the change.

Commit Message Trailer(s)

If lane install hooks has been run, then git hooks are active and you can add notes while writing commit messages. Include a Why: trailer when the finding belongs with a commit:

text
make verification constant-time

Why: src/auth.rs#fn verify | early return leaks token length

The form is Why: <path>[#<anchor>] | <text>. The path and | separator are required; omit the anchor to target the whole file.

Run lane install hooks once if trailers are not being captured.

Manually

Record a finding directly when it does not belong to a commit, or if lane install hooks has not been run:

bash
lane note add src/auth.rs -a "fn verify" "must stay constant-time"

Supplying text is non-interactive and defaults to @file when -a is omitted. Omit the text only when you want the interactive prompt.

Anchors

An anchor describes what a note is about:

anchormatches
fn verifya declaration by kind and name
verifya uniquely named declaration
#script, #stylea top-level component block
## Rate limitinga Markdown section
@filethe whole file

Run lane anchors <path> --json and prefer the canonical anchor it returns. Ambiguous declaration names are refused with their available choices.

Rules

  • Never edit .lane/ by hand; use the lane note commands.
  • Do not pass --dirty unless the lane should inherit the parent checkout's uncommitted work.
  • Keep each note to one constraint.
  • Do not record what a commit changed.

Run lane --help for the command list, or lane <command> --help for details.

With the skills CLI, run `npx skills add lukeed/lane --skill lane -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/lane, .gemini/skills/lane, .github/skills/lane and .opencode/skills/lane in your project.

What does Lane need to run?

SKILL.md names no scripts, command-line tools or credentials: Lane is instructions for the agent only.

Does Lane access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Lane safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
