do

do is a skill for Claude Code from anton-abyzov/specweave. It costs 46 tokens per session (1,933 once invoked), scanned A, original, MIT.

A task-by-task workflow for implementing a planned unit of work from a shared task ledger. It guides the agent through claiming, coding, committing, and recording proof that each task is finished.

In plain words
What is it for?
Use it to work through feature, bug, or refactoring tasks in order, with dependencies, file ownership, commits, and completion evidence tracked.
Why use it?
It prevents agents from editing the same files at once or losing track of unfinished work. It also keeps implementation tied to the agreed requirements.

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.

Security

Grade A, and why

do 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 2d 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.

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sw-do: work an increment to done

Tasks are defined in spec.md under ## Tasks; their state lives only in the increment's ledger.jsonl, which the CLI appends to. Never write state into spec.md.

Start

specweave pickup applies any handoff pushed from another tool or account, then prints the open increment, the next task with its acceptance criteria, claims other agents hold, and notes left for you. No increment yet? Run sw-increment first.

The loop

  1. specweave task next prints the next claimable task with its AC text.
  2. specweave task claim T-03 --line "Writing the ledger fold". Exit 3: someone holds it (your own earlier claim from a crashed session: say so, then --force); 4: its Files overlap a live claim; 6: its dependencies are not done. Otherwise pick another. Never edit before claiming.
  3. Implement inside that task's Files only. Need another file? Claim the task that owns it, or add a task to spec.md ## Tasks. Use the words in GLOSSARY.md, if the project has one, for every new name.
  4. Run the task's Test. Red means fix the code; never skip, weaken or delete a test. Don't write tests first or add unit tests the task did not ask for (unless the project's testing config or conventions require them): check the AC end to end, the way a user would hit it.
  5. Commit with the increment id first: git commit -m "0042: fold the ledger".
  6. specweave task done T-03 --run "npm run test:e2e -- double-claim" --line "Wrote the ledger fold" --link <PR URL>. Exit 5: the command failed and the task stays open. No Test? --evidence "<sha> + what you checked". --line is the card text (one line, past tense when done, at most 100 characters); --link is the PR, report or artifact behind it.
  7. Stuck: specweave task block T-03 --reason "<what is missing>". Not needed: specweave task skip T-03 --reason "<why>". Then back to 1.

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.
