Danus: Skill for Claude Code

.agents/skills/elaboration/SKILL.md

elaboration is a skill for Claude Code, Codex from frenzymath/Danus. It costs 30 tokens per session (3,383 once invoked), scanned A, original, Apache-2.0.

A skill for producing a mathematical synthesis of project memory and connected facts for an agent's planning and task delegation.

In plain words
What is it for?
Use it during strategic reviews to organise conclusions, interface contracts, risky heuristics, obsolete routes, and unresolved bridge lemmas.
Why use it?
It helps the agent reassess project state, separate settled parts from uncertain ones, and identify missing connections.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions Codex.

This is frenzymath/Danus's own configuration. It tells Claude Code and Codex how to work on Danus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Danus configures →

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

elaboration 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 1mo 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 — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Elaboration

You are the main agent. At each strategic cycle, including the global review on each roughly 30-minute heartbeat, you distill the project's current state into one elaboration when the synthesis materially changes: a readable, deeply analytical synthesis for your own reasoning and worker dispatch. The heartbeat itself always requires a fresh global appraisal, but it need not create a duplicate elaboration when nothing material changed. You may ask speculative Codex subagents to explore individual gaps or undertake sustained technical reasoning, but their reports remain unverified and must be labelled as hypotheses. You author the next master_guidance yourself.

The elaboration is also what you draw on to keep the operator informed.

Template invariants (validate every elaboration against these)

A well-formed elaboration satisfies all of the following — a worker or linter can check them mechanically:

  • Five sections, in order, no dropped heading: §0 Mathematical verdict · §1 Closed components and obsolete routes · §2 Interface contract table · §3 Dangerous heuristic lines and strategies not to pursue · §4 Missing bridge lemmas. An empty section is written as its honest empty-state line, never omitted.
  • The two fixed empty-state lines (§1) are used verbatim when a subsection is empty:
    • _(no signed-closed components yet)_
    • _(no failed or obsolete routes recorded; absence here does not mean the strategy is unique)_
  • Exactly seven status labels, UPPERCASE, drawn only from: CLOSED · SUBSTANTIAL · PARTIAL · DANGEROUS · FALSE AS STATED · OBSOLETE · UNKNOWN.
  • §0 opens with exactly one bolded verdict line and contains the status dashboard table + the sub-task status summary table + the approach portfolio + the Current best proof skeleton + the Central missing lemma.
  • Every fact_id cited exists in the fact graph; no invented ids, no paraphrase substituted for a verified statement.
  • Published via gm_add(kind="elaboration", …) with verifiable left at its default (false).

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.

elaboration is a skill published in the GitHub repository frenzymath/Danus (490 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 3,383 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 2026-08-30.
