full-cycle

full-cycle is a skill for Claude Code, Codex from Mark-Life/agent-skills. It costs 74 tokens per session (1,443 once invoked), scanned A, original, MIT.

A workflow for taking an idea or goal through research, human decisions, implementation, review, and a pull request ready for approval. A pull request is a proposed set of code changes that teammates can inspect before merging.

In plain words
What is it for?
It helps survey options, choose an approach, implement changes, check them with independent review, and prepare a dry, reviewable pull request.
Why use it?
It keeps broad investigation, decisions, coding, measurement, and repeated review in one process. It also distinguishes measured results from work that was not actually run.

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

full-cycle 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 yesterday.

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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Full cycle

Carry work from an idea to a PR a stranger can approve. Spend tokens freely: fan out subagents in dynamic workflows wherever breadth, independent opinions or adversarial checks make the answer better. The human spends attention: they steer and correct, the agent does the deep work.

Five words carry this skill. Tier list: every survey ends in a ranked list with one plain reason per row. Recommended: every question to the human carries the agent's own pick. Receipts: every number was really measured; what was not run is said. Skeptic: every finding is reproduced by a second agent before anyone acts on it. Dry: review ends only when rounds stop producing real findings.

Asking the human

Research until you could make the call yourself, then hand the human the call. Each ask lays out what they need to decide and nothing more: the options, what each costs and gains, what it touches. Mark your pick (recommended) with one plain reason. The human confirms, picks another, or redirects.

The human switches context all day, and a thread may span weeks. Each message stands alone: answer first, plain words, one picture where a picture is faster than a paragraph. A Mermaid map for structure and flow, a motion schematic for what changes over time (pr-issue skill, motion.md), a screenshot or slowed real recording for what a user sees. Style is owned by the agent-to-human skill.

Peers

From what the product is, name its peers: open-source apps and libraries that face the same problem. For a coding-agent client that means other agent UIs, editors and CLIs. Read their code, not their marketing. Every research stage answers "how did others solve this problem?" with file paths as evidence.

Stages

Gates marked ask wait for the human. Everything else runs unattended.

  1. Survey. A workflow fans out across the problem space — for "optimize the app": rendering, startup, bundle, network, memory, server latency. Each agent measures or reads, not guesses, and checks the peers. Return a tier list of areas. Ask which to take.
  2. Deep dive. Inside the chosen area, build or reuse a repeatable measurement, take a baseline, then return a tier list of concrete targets with their measured cost. A target whose cost is an estimate gets a probe: a throwaway fix, measured, reverted. Probes routinely refute the obvious suspect; rank by probe results.
  3. Options. For the top target, 2–4 fixes, always including the answer to "is there a stupid simple solution we're not thinking about?" and the peers' approach. Prototype the serious ones in isolated worktrees and measure them interleaved. For each: upside, downside, what else it touches, and a picture of how the system changes. Ask which to build.
  4. Pre-review. Before coding, one agent attacks the chosen design with "what have we missed?" and returns the final brief.
  5. Implement in its own worktree and branch, following the repo's AGENTS.md/CLAUDE.md and owning specs.
  6. Review until dry. See below.
  7. Evidence. Rebuild before measuring; stale builds lie. Before and after run interleaved, five or more rounds, median with spread. Render or call counts beat milliseconds when timings are noisy. Run the full test suite once. Record media: slow a real recording until the difference is visible, and add a capture-only on-screen marker (a frame counter, a timestamp) when the change is about time.
  8. PR. Write it with the pr-issue skill: before/after table, the options rejected and why, future work, visuals. Slice into one-problem PRs, stacked when they build on each other. Show the human the local media paths before any PR body changes. Ask before opening anything on a repo the human does not own.

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.

full-cycle is a skill published in the GitHub repository Mark-Life/agent-skills (3 stars, last pushed 2d ago), licensed MIT. It adds 74 tokens to every session and 1,443 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-05.
