coding-agent

coding-agent is a skill for Claude Code, Codex from ssmurfgg04-gif/context-m. It costs 19 tokens per session (734 once invoked), scanned A, original, Apache-2.0.

A coding workflow guide covering planning, implementation, verification, testing, task state, and user preferences.

In plain words
What is it for?
Use it when a user asks for code implementation and needs help breaking down, carrying out, and checking the work.
Why use it?
It gives structure to software work while leaving execution under the user’s control and avoiding automatic code runs or network requests.

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

coding-agent 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 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.

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

When to Use

User explicitly requests code implementation. Agent provides planning, execution guidance, and verification workflows.

Architecture

User preferences stored in ~/code/ when user explicitly requests.

~/code/
  - memory.md    # User-provided preferences only

Create on first use: mkdir -p ~/code

Quick Reference

Topic File
Memory setup memory-template.md
Task breakdown planning.md
Execution flow execution.md
Verification verification.md
Multi-task state state.md
User criteria criteria.md

Scope

This skill ONLY:

  • Provides coding workflow guidance
  • Stores preferences user explicitly provides in ~/code/
  • Reads included reference files

This skill NEVER:

  • Executes code automatically
  • Makes network requests
  • Accesses files outside ~/code/ and the user's project
  • Modifies its own SKILL.md or auxiliary files
  • Takes autonomous action without user awareness

Core Rules

1. Check Memory First

Read ~/code/memory.md for user's stated preferences if it exists.

2. User Controls Execution

  • This skill provides GUIDANCE, not autonomous execution
  • User decides when to proceed to next step
  • Sub-agent delegation requires user's explicit request

3. Plan Before Code

  • Break requests into testable steps
  • Each step independently verifiable
  • See planning.md for patterns

4. Verify Everything

After Do
Each function Suggest running tests
UI changes Suggest taking screenshot
Before delivery Suggest full test suite

5. Store Preferences on Request

User says Action
"Remember I prefer X" Add to memory.md
"Never do Y again" Add to memory.md Never section

Only store what user explicitly asks to save.

Workflow

Request -> Plan -> Execute -> Verify -> Deliver

Common Traps

  • Delivering untested code -> always verify first
  • Huge PRs -> break into testable chunks
  • Ignoring preferences -> check memory.md first

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

coding-agent is a skill published in the GitHub repository ssmurfgg04-gif/context-m (1 stars, last pushed today), licensed Apache-2.0. It adds 19 tokens to every session and 734 once invoked, about $0.0001 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 2026-08-31.
