aragora: Skill for Claude Code

.agents/skills/elves-aragora/SKILL.md

elves-aragora is a skill for Claude Code, Codex from synaptent/aragora. It costs 167 tokens per session (2,911 once invoked), scanned A, original, MIT.

An autonomous development workflow for the Aragora code repository that works through development tasks in repeated batches.

In plain words
What is it for?
It is for requests such as implementing a plan overnight or continuing development while the user is away. It is not intended for one-off edits.
Why use it?
It supports unattended work while requiring tests, multi-agent review, evidence records, and a final decision before a batch is considered complete.

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is synaptent/aragora's own configuration. It tells Claude Code and Codex how to work on aragora 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 aragora 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

elves-aragora 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.

Elves (aragora-native)

This is an aragora-bound fork of the Elves autonomous-development skill. The unattended Ralph Loop (try → check → feed back → repeat across sprint-sized batches, surviving context compaction) is unchanged. What changes is the gate. Upstream Elves closes a batch on npm test plus a GitHub PR comment. In aragora, "the tests are the watch" is necessary but not sufficient: a batch is only complete when it has passed aragora's own evidence-first governance.

Positioning. aragora's README states it "does not sell lights-out autonomy as the default story" and "does not advance work without evidence, review, and clear terminal states." This fork honors that. It keeps Elves' overnight leverage but subordinates it to receipts, model quorum, and human settlement. The elves work the night shift; aragora decides what is allowed to land.

When to use

Trigger inside ~/development/aragora (or any aragora checkout) when the user wants a long, unattended run: "run overnight", "I'm going offline until 8", "implement this plan end-to-end", "keep going without me", "do not stop". For one-off single edits, do not use this skill.

The two-call handoff (unchanged from Elves)

  1. Stage the run — clean the plan, generate the survival guide / learnings / execution log from the templates in references/, claim a dedicated branch + worktree, run preflight, and stop. See references/kickoff-prompt-template.md.
  2. Launch in a fresh call with a short, behavior-heavy prompt.

The aragora validation gate (the core difference)

Every batch runs through references/validation-gate-aragora.md. In short, a batch is not complete until all of the following hold, in order:

  1. Local truth. Project validation passes against current HEAD: pre-commit run --all-files, mypy (no new errors above .mypy-baseline), and the relevant pytest slice. Total test count must never decrease.
  2. Adversarial review = a debate, not a comment. Run a heterogeneous-model adversarial review of the batch diff via aragora itself (e.g. aragora ask framed as a review of git diff <default-branch>...HEAD, or the repo's aragora-review-gate path). Capture the exact head SHA reviewed, the model/provider families, independence from the authoring lane, the recommendation, and any dissent. Unresolved dissent blocks the batch.
  3. Receipt. Produce a DecisionReceipt for the batch decision and verify it: aragora verify <receipt.json> (and/or aragora receipt verify). The receipt binds the decision to the reviewed SHA. No receipt → batch not closed.
  4. Tier classification + settlement. Classify the batch against docs/REVIEW_AUTHORITY_PRINCIPLES.md (Tier 0-4):
    • Tier 0-2 (docs/tests, additive internal, live automation/CLI/observability): a green, receipt-backed model quorum with no unresolved dissent is sufficient to record settlement autonomously and continue. Still never merge by default — settlement records the authorization packet; the human or a recorded merge-on-green preference plus helper authorization does the merge. §Conductor never grants merge authority by itself.
    • Tier 3-4 (semantic correctness, persistence, security/RBAC/auth, public API/SDK, migrations; or secrets/deployment/workflow policy/destructive ops/merge-authority self-modification): HARD STOP. The model quorum prepares the packet, but the run must pause and require explicit human risk acceptance (the aragora/human-settlement signal) before that batch is considered landed. Continue with other non-blocked batches if any exist; otherwise checkpoint and wait.

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.

elves-aragora is a skill published in the GitHub repository synaptent/aragora (11 stars, last pushed yesterday), licensed MIT. It adds 167 tokens to every session and 2,911 once invoked, about $0.0008 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 2026-08-30.
