do

do is a skill for Claude Code, Codex from doodledood/manifest-dev. It costs 52 tokens per session (6,638 once invoked), scanned A, original, MIT.

A task executor that follows a written Manifest, a plan containing deliverables, requirements, and checks. It works through the deliverables and verifies each acceptance criterion and global rule.

In plain words
What is it for?
Use it to execute a manifest-backed feature, fix, refactor, or other defined task, including its required verification checks.
Why use it?
It turns a defined plan into tracked implementation work and makes the required results explicit. It also records important deviations or changes in approach instead of hiding them.

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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Execution

What binds the run

Work toward the manifest's Deliverables in the order listed. Acceptance Criteria and Global Invariants are the binding layer — they are what the run owes, and gates are the only thing that can hold it open. Process Guidance is advisory: recommendations on how to work, weighed rather than enforced, and set aside when the work is better for it — name every departure on whichever terminal path the run takes — completion summary, escalation payload, or pending summary — and in the execution log too when a log is being kept, since advisory only stays safe while departing stays visible. The Initial Approach and the Deliverable order are likewise plan, not contract: pivot either when reality diverges, and name the deviation the same way a departure is named. Resequence when execution changes what the order was built on — a real dependency the order missed, or a shift in which Deliverable is now least proven, since proving the leading approach is exactly what ordering by uncertainty is for. Every judgment the run weighs rather than obeys — departing from Process Guidance, pivoting the Initial Approach, resequencing, choosing what stays below a bar on a terminal path — steers by the manifest's Intent: better than the Problem's baseline story, within the size the Appetite says the problem is worth, comparing down to that baseline rather than up to an ideal.

Running gate evaluations

Resolve execution policy before implementation starts. --verification accepts per-gate, consolidated, or self and defaults to per-gate; after resolving that default, load exactly one matching reference: references/per-gate-verification.md, references/consolidated-verification.md, or references/self-verification.md. The selected reference owns evaluator topology, evaluator provenance, and mode-specific evidence wording for completion and unattended backstops. --verifier-model <model> is optional and applies to the independent modes: when supplied, use it for every verifier execution and reject the policy before work if the active host cannot honor that selector; when omitted, verifier executions inherit the invoking context's model choice. The selected mode, the verifier-model provenance, and whether --exhaustive-verification is in force are fixed for the run and never change in response to cost, elapsed rounds, findings, or model preference. A later invocation changing any of them — including adding or dropping the flag — starts a new run with a fresh gate ledger rather than mixing evidence provenance. None of them is written into the Manifest.

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.

do is a skill published in the GitHub repository doodledood/manifest-dev (72 stars, last pushed 4d ago), licensed MIT. It adds 52 tokens to every session and 6,638 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
