context-prime

context-prime is a skill for Claude Code, Codex from strikersam/autonomous-ai-agency. It costs 28 tokens per session (666 once invoked), scanned A, original, MIT.

A repository-reading workflow that gives a coding agent an overview of a codebase before it starts a substantial task.

In plain words
What is it for?
Use it when joining an unfamiliar repository, starting a complex feature, or investigating a difficult bug across several files.
Why use it?
It reduces wrong assumptions about the project’s structure, rules, and existing patterns. This helps avoid unnecessary or conflicting code changes.

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

context-prime 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 7d 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.

Skill: context-prime

Purpose

Prime Claude with deep repository context before starting any significant task. Ensures Claude has a full mental model of the codebase architecture, conventions, and constraints before writing a single line of code.

Trigger

Use at the start of:

  • A new coding session on an unfamiliar area
  • A complex feature that touches many files
  • A debugging session for a hard-to-reproduce bug
  • Onboarding to a new repository

Process

Step 1: Read Core Docs

In order:

  1. CLAUDE.md — primary instructions and conventions
  2. README.md — project overview and purpose
  3. TOOLS.md — available tooling
  4. agent/CLAUDE.md — agent-specific context (if exists)
  5. Any docs/ folder overview files

Step 2: Map the Architecture

Scan the top-level directory structure. For each major directory:

  • Identify its purpose
  • Note key files within it
  • Understand how it connects to other directories

Build a mental map: [module] → [responsibility] → [interfaces with]

Step 3: Find Conventions

Look for patterns across 5-10 representative files:

  • Naming conventions (files, functions, classes, variables)
  • Import organization style
  • Error handling patterns
  • Testing patterns (test file location, naming, fixtures)
  • Comment/docstring style
  • Type annotation usage

Step 4: Understand Data Flow

Trace the main data flow through the system:

  • Entry points (API routes, CLI commands, event handlers)
  • Core processing logic
  • Storage/persistence layer
  • Output/response formation

Step 5: Identify Constraints

Note any explicit constraints from CLAUDE.md or comments:

  • Performance-sensitive areas
  • Security boundaries
  • Deprecated patterns to avoid
  • In-progress refactors to be aware of

Step 6: Declare Readiness

Output a structured context summary:

## Context Prime Complete

### Architecture

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.

context-prime is a skill published in the GitHub repository strikersam/autonomous-ai-agency (11 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 666 once invoked, about $0.0001 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 2026-08-31.
