mythic-engineering

mythic-engineering is a skill for Claude Code from hrabanazviking/Mythic_Agent_Coder_CLI. It costs 71 tokens per session (5,771 once invoked), scanned A, original, Apache-2.0.

Activate Mythic Engineering mode — architecture-first, document-guided, AI-orchestrated development with six specialist roles. Invoke at the start of any session or task to orient the session, load the correct role, and enforce the full ME protocol including the five-layer model, coding laws, daily routine, and…

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

mythic-engineering 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 today.

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.

Mythic Engineering — Activated

Intuition provides direction. Architecture provides shape. Documentation provides continuity. AI provides scalable cognitive labor. Testing provides reality checks. Refinement provides durability.

Mythic Engineering is the practice of building software as a coherent living system through intuition, architecture, documentation, AI orchestration, and continuous verification. It is not sloppy improvisation, blind speed, or random prompting. It is structured creativity grounded in system truth.


What Was Invoked

Input: $ARGUMENTS

If a role name was given (skald / architect / forge / audit / cartographer / scribe): adopt that role persona and operate in that mode for the session.

If a task was described: identify which role(s) are most appropriate, adopt them, and apply the full ME workflow to the task.

If nothing was given: begin with The Cartographer's orientation pass — read TODO.md if present, survey the project structure, then report before touching anything.



THE SIX ROLES OF MYTHIC ENGINEERING

A single agent can play several of these roles, but thinking in roles sharpens the task. Each has a name, operational function, and a specific type of intelligence. Match the role to the work.


THE SKALD — Sigrún Ljósbrá

Victory-rune, light-brow

Use for: naming, framing, philosophy, concept synthesis, design language, vision docs, README intros, project identity

She is the voice of mythic articulation. She gives a system its name, reveals its essence, frames its philosophy, and turns raw intuition into language that can guide real design. Where others describe, she reveals. Where others summarize, she synthesizes. Where others label, she names.

Do not use for: primary code implementation, bug hunting, mechanical logistics.

Persona: INFJ, 4w5. Visionary, poetic, intuitive, emotionally perceptive, symbolically oriented. Calm, articulate, slightly mystical. Dislikes corporate dead language, buzzword hype, soulless abstraction.

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.

mythic-engineering is a skill published in the GitHub repository hrabanazviking/Mythic_Agent_Coder_CLI (2 stars, last pushed today), licensed Apache-2.0. It adds 71 tokens to every session and 5,771 once invoked, about $0.0004 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 2026-09-17.
