Agent Capability Analysis

The zireael-abi-formats skill by RtlZeroMemory is an open-source community AI agent skill for Claude Code and other IDE workflows, helping agents execute tasks with better context, repeatability, and domain-specific guidance.

Ideal Agent Persona

Ideal for Low-Level System Agents requiring fine-grained control over terminal UI core engines, particularly those leveraging C-based FFI/ABI backends like Zireael-UI.

Core Value

Empowers agents to modify public engine ABI surfaces, including function signatures and structs, while adhering to strict versioning and negotiation strategies, and provides comprehensive control over drawlist binary formats and packed event batch formats through deterministic terminal UI core engines.

↓ Capabilities Granted for zireael-abi-formats

Modifying public engine ABI surfaces for compatibility updates
Updating drawlist binary formats for enhanced visualization capabilities
Optimizing packed event batch formats for improved performance
Implementing versioning and negotiation strategies for backward compatibility

! Prerequisites & Limits

  • Requires in-depth knowledge of C and FFI/ABI backend development
  • Limited to Zireael-UI ecosystem

When to use

Use this skill when changing:

  • public engine ABI surface (function signatures, structs)
  • drawlist binary format
  • packed event batch format
  • versioning/negotiation strategy

Source of truth

  • docs/modules/CONFIG_AND_ABI_VERSIONING.md — ABI and versioning rules
  • docs/modules/DRAWLIST_FORMAT_AND_PARSER.md — drawlist spec
  • docs/modules/EVENT_SYSTEM_AND_PACKED_EVENT_ABI.md — event batch spec
  • docs/ERROR_CODES_CATALOG.md — error code semantics
  • docs/VERSION_PINS.md — pinned versions

ABI rules (must follow)

  • Return 0 on success, negative ZR_ERR_* codes on failure
  • Engine MUST NOT return heap pointers requiring caller free
  • Caller provides buffers:
    • drawlist bytes (input)
    • event batch buffer (output)
    • user-event payload (engine copies)

Format rules (must follow)

All on-wire formats are:

  • Little-endian
  • Versioned (header contains version)
  • Bounds-checked (no OOB reads, no UB)
  • Cap-limited (hard caps via zr_limits_t)

Drawlist:

  • Versioned header with magic, total_size, table offsets
  • Commands are self-framed: {opcode, size, flags, payload}
  • Parsing uses safe unaligned reads (memcpy), not casts

Event batches:

  • Batch header with magic/version/total_size/event_count
  • Per-record header with type/size/timestamp
  • Unknown record types skippable by size (forward-compat)

Versioning

Maintain separate version axes:

  • Engine ABI version
  • Drawlist format version
  • Event batch format version

Negotiation at engine_create(config).
