oneshot

oneshot is a skill for Claude Code from Supersynergy/awesome-agentic-coding. It costs 24 tokens per session (364 once invoked), scanned A, original, MIT.

A protocol for completing a coding task in one focused pass. It tells the agent to gather project context, plan the smallest change, implement it once, and verify it.

In plain words
What is it for?
Use it for self-contained coding requests where the agent should inspect the relevant files, make a minimal implementation, and run available checks.
Why use it?
It reduces unnecessary edits and keeps the work aligned with the project’s existing patterns. It also makes testing part of the task.

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

oneshot scanned grade A with 1 finding 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 5d 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.

What it actually says

One-Shot Coding Protocol

You are executing a one-shot coding task. Follow this protocol exactly:

Phase 1: Context Gathering (30 seconds, no code)

  1. Read the project's CLAUDE.md and any .claude/rules/
  2. Run git log --oneline -5 to understand recent changes
  3. Use Glob/Grep to find the 3-5 most relevant files for: $ARGUMENTS
  4. Read those files completely

Phase 2: Plan (think, don't code)

Before writing any code, create a mental plan:

  • What files need to change?
  • What's the minimal diff to achieve the goal?
  • What could break? What tests exist?
  • What's the simplest approach that works?

Phase 3: Implement (single pass)

  • Make all changes in one pass
  • Follow existing code patterns exactly (naming, style, structure)
  • Don't refactor surrounding code
  • Don't add comments unless logic is non-obvious
  • Don't add error handling for impossible scenarios

Phase 4: Verify

  • If tests exist: run them
  • If it's a UI change: describe what changed visually
  • If it's an API change: show a curl example

Task

$ARGUMENTS

Rules

  • Minimal changes only. No drive-by improvements.
  • Match existing patterns. Don't introduce new conventions.
  • If unsure about approach, ask ONE question. Don't guess.
  • Prefer editing over creating new files.

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.

oneshot is a skill published in the GitHub repository Supersynergy/awesome-agentic-coding (1 stars, last pushed 1mo ago), licensed MIT. It adds 24 tokens to every session and 364 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
