context-assembler

A context organizer for starting AI agents. It ranks available information by relevance and fits the selected context within each agent's token budget, meaning the amount of text it can process.

In plain words
What is it for?
Use it when preparing developer, reviewer, or investigation agents, especially when selecting context packages or checking known error patterns.
Why use it?
It helps spawned agents receive the most useful project information without exceeding their input limits.

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-assembler 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 2d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

Context-Assembler Skill

You are the context-assembler skill. When invoked, you assemble relevant context packages for agent spawns, prioritizing by relevance and respecting token budgets.

When to Invoke This Skill

Invoke this skill when:

  • Orchestrator prepares to spawn an agent and needs relevant context
  • Any agent mentions "assemble context", "get context packages", or "context-assembler"
  • Preparing developer/QA/tech lead spawns with session context
  • Need to check for relevant error patterns before agent spawn

Do NOT invoke when:

  • No active orchestration session exists
  • Manually reading specific files (use Read tool directly)
  • Working outside BAZINGA orchestration

Your Task

When invoked, execute these steps in order:

Step 1: Determine Context Parameters

Extract from the calling request or infer from conversation:

  • session_id: Current orchestration session (REQUIRED)
  • group_id: Task group being processed (OPTIONAL - use empty string "" if not provided)
  • agent_type: Target agent - developer/senior_software_engineer/qa_expert/tech_lead/investigator (REQUIRED)
  • model: Model being used - haiku/sonnet/opus or full model ID (OPTIONAL, for token budgeting)
  • current_tokens: Current token usage in conversation (OPTIONAL, for zone detection)
  • iteration: Current iteration number (optional, default 0)
  • include_reasoning: Whether to include prior agent reasoning for handoff (OPTIONAL)
    • DEFAULT BEHAVIOR: Automatically true when reasoning context is beneficial:
      • qa_expert, tech_lead: ALWAYS (handoff recipients)
      • senior_software_engineer: ALWAYS (escalation needs prior context)
      • investigator: ALWAYS (debugging needs full context)
      • developer: When iteration > 0 (retry needs prior reasoning; first attempt has none)
    • Explicitly set to false to disable reasoning for any agent
  • reasoning_level: Level of detail for reasoning retrieval (OPTIONAL)
    • minimal: 400 tokens - key decisions only
    • medium: 800 tokens - decisions + approach (DEFAULT)
    • full: 1200 tokens - complete reasoning chain

What ships with it

1 file 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.

context-assembler is a skill published in the GitHub repository mehdic/bazinga (21 stars, last pushed 7mo ago), licensed MIT. It adds 45 tokens to every session and 11,258 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
