ultra-adlc

ultra-adlc is a skill for Claude Code, Codex from KonghaYao/peri. It costs 69 tokens per session (13,194 once invoked), scanned A, original, Apache-2.0.

A workflow skill for test-driven development (TDD), where tests are written before the code and the implementation is then refined. It runs the red, green, and refactor stages with validation checks.

In plain words
What is it for?
Use it to create failing tests first, implement enough code to pass them, and then improve the design while keeping the tests passing.
Why use it?
It gives feature work a fixed test-first process and checks that the implementation passes tests before refactoring. This helps catch regressions while the code is being built.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: names the AskUserQuestion tool.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./.peri/adlc/.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
  • medium Excessive Agency · line 407
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

ultra-adlc 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 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.

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.

Ultra-ADLC

Turn one natural-language goal into a complete, audited delivery. The Main Agent preserves the user's stated intent and authority boundaries, delegates ordinary design adjudication to an independent opus or fable arbiter, and coordinates all execution without making the user supervise implementation choices.

This skill is self-contained. Use the existing deferred Workflow tool and its existing agent, parallel, pipeline, phase, and ordinary JavaScript control flow only. Do not add a DAG/runtime/RPC/event/TUI primitive or a third logical workflow.

Admission and completion invariants

  • This mode is for a very large end-to-end task. If it was selected implicitly for ordinary work, do the work normally instead. An explicit /ultra-adlc invocation always selects this mode.
  • There are exactly two logical workflows: discovery-design and delivery-convergence. A resumed physical run remains part of its original logical workflow.
  • The Main Agent is the only user-interaction seam. Workflow Agents cannot and must not call AskUserQuestion. User adjudication is not the default: ordinary reversible product, scope, risk, and design choices go to an independent opus or fable Decision Arbiter. Ask the user only for missing product intent, new authority, secret or external state, legally or financially consequential acceptance, irreversible action, or two outcomes that materially affect the user and cannot be resolved from the stated goal.
  • There are exactly three contracts: intent.md, execution.md, and evidence.md. Manifests, decisions, handoffs, artifacts, and learning records are audit records, not extra contracts.
  • Legal terminal states are complete, blocked, and cancelled. There is no partially_complete. "Core complete", "mostly complete", an exhausted context, or a normally exited Workflow are never completion evidence.
  • Assessor verdicts are only complete | incomplete | blocked. Do not invent a fourth verdict such as complete_with_known_gaps. Every required check in the accepted Verification Plan must have current, attributable evidence. Unrun or missing required tests, missing required coverage evidence, and unevidenced acceptance scenarios are coverage gaps: return incomplete when fixable inside Workflow 2, or blocked when an external dependency or authorization prevents obtaining the evidence. Keep fixable incomplete items inside the Workflow 2 loop. Remaining Risks may contain only non-required checks outside the accepted Verification Plan (including an out-of-plan E2E or preexisting flake); it cannot excuse missing required evidence or reduce any completion percentage.
  • A task is complete only after one independent Completion Assessor in the current assessment round proves 100% coverage. Fixable gaps remain inside logical Workflow 2 and loop until they are fixed and reassessed.
  • Never commit, push, publish, deploy, delete material data, or mutate an external system unless the user separately and explicitly authorizes that action.

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.

ultra-adlc is a skill published in the GitHub repository KonghaYao/peri (163 stars, last pushed today), licensed Apache-2.0. It adds 69 tokens to every session and 13,194 once invoked, about $0.0003 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 2026-09-03.
