What it does

Adr Authoring is an agent skill from magnus919/agent-skills. Write, review, and maintain architecture decision records with clear context, alternatives, consequences, confirmation links, and lifecycle governance. Use when a consequential technical decision or its enforceable architectural constraint must remain understandable. Do not use for system-wide evolutionary architecture design, general observability, or operating a named test or CI tool.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files (for example `README.md`, `evals/evals.json` and `references/adr-format.md`). Compatibility notes: No runtime dependency.

It sits in Development, covering Architecture decision records. The repository describes itself as: Curated collection of AI agent skills for Hermes and other agent frameworks. The licence is MIT.

When your agent uses it

  • A consequential technical decision
  • Its enforceable architectural constraint must remain understandable
  • System-wide evolutionary architecture design
  • General observability

Example prompts

  • “/adr-authoring”

Requirements

  • Compatibility (from SKILL.md): No runtime dependency.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read the repository's agent instructions, contributing guide, ADR index, template, and a few recent records before drafting. Reuse the…
  2. Treat this skill's layouts and templates as fallbacks only. Do not move, renumber, rename, or rewrite existing ADRs to fit the skill. If…
  3. If no convention exists, use a flat docs/adr/ directory, stable sequential identifiers, a small index, and a lightweight Nygard template…

What it can do on your machine

Read from SKILL.md and the folder at commit 22b4723. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • thinkrelevance.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    No runtime dependency.

    From compatibility in the SKILL.md frontmatter.

Context cost

Adr Authoring loads about 2.1k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 930 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~101
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~14k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ADR Authoring

Architecture Decision Records for capturing design rationale. ADRs supply the temporal dimension — decisions over time — that structure-only views (C4) miss.

Start with Repository Conventions

  1. Read the repository's agent instructions, contributing guide, ADR index, template, and a few recent records before drafting. Reuse the established location, numbering, headings, status vocabulary, approval process, and amendment policy.
  2. Treat this skill's layouts and templates as fallbacks only. Do not move, renumber, rename, or rewrite existing ADRs to fit the skill. If local conventions conflict, preserve the existing records and identify the specific conflict before changing the convention.
  3. If no convention exists, use a flat docs/adr/ directory, stable sequential identifiers, a small index, and a lightweight Nygard template (MADR when option analysis needs more structure). Read references/project-setup-guide.md only when establishing a new decision log.
  4. Read references/adr-to-pyramid-mapping.md only if the project already uses artifact pyramids or the user requests that organization. Index links can provide layered navigation without relocating canonical records.

Decision, Approval, and Evidence

Keep these three facts distinct, using the repository's existing fields or linked records:

  • Proposal: What is recommended, why, alternatives, consequences, and unresolved questions. A draft or recommendation is not an accepted decision.
  • Decision authority and scope: Who approved what, when, and for which environment or stage. Approval to experiment permits the bounded experiment; it does not establish production adoption. An accepted ADR may authorize only an experiment if that scope is explicit. Do not invent a decider, date, or broader approval.
  • Implementation evidence: Links to changes, checks, observed results, and remaining gaps. Acceptance does not prove implementation; passing a prototype check does not prove production readiness. Label a validation plan as planned until results exist.

For example, “approved an isolated database trial” supports a trial-scoped decision. A successful restore rehearsal is evidence for the tested recovery scenario; neither fact alone means “database adopted in production.”

ADR Lifecycle

Use the local lifecycle and amendment rules. When absent, use proposed → accepted | rejected, with accepted decisions later deprecated or superseded by a linked successor.

Preserve accepted rationale. By default, a changed decision gets a new ADR; update the old record's status and successor link while retaining its identifier and location. If the repository uses living documents, make dated, attributable amendments under its policy. Do not impose mutability on an immutable log or replace a living-document process with an immutable one.

Record rejection and supersession reasons, maintain the index, and preserve links. Review format and meeting length follow the team's process; acceptance requires evidence of the relevant decision authority, not a mandatory ceremony.

Template Selection

Use the repository template first. This table applies only when no template is established.

WhenTemplateSections
Quick decision, single rationaleNygardStatus, Context, Decision, Consequences
Multi-option trade-off analysisMADRDecision Drivers, Considered Options, Pros/Cons, Links
High-stakes, regulatory, complianceTyree & Akerman12 sections: Issue, Positions, Argument, Implications, etc.
Vendor/procurement decisionBusiness CaseEvaluation criteria, Cost/SWOT, Recommendations
QA/contract-driven environmentPlanguageTag, Gist, Priority, Stakeholders, Risks

Full catalog with section-by-section guidance in references/adr-format.md.

File Naming Conventions

Follow local naming first. For a new log, use present tense imperative verb phrases, lowercase-dashes, .md extension:

001-choose-database.md
002-format-timestamps.md
003-manage-secrets.md

Status lives in the document header, not the filename — status changes shouldn't require renames.

Teamwork & Governance

  • Who can create: Any team member who has read the ADR process docs
  • What justifies: Decisions affecting future "why", cross-team coordination, long-term maintainability, external interfaces
  • What usually does NOT: Routine changes already covered by standards. Record a bounded experiment when its authorization, constraints, or consequences need durable rationale.
  • Roles per ADR: Primary contact, secondary contact, accountable team
  • Amendments: Follow repository policy; preserve decision history and distinguish new evidence from a changed decision.

See references/adr-format.md for the full governance model and teamwork questions.

Fitness-Function Confirmation

Applicability: Use when an ADR makes a claim that can be checked through code, configuration, runtime telemetry, a scheduled audit, or a bounded human review.

Read references/fitness-functions.md to select the function's scope, cadence, evidence, threshold, owner, exception path, and retirement rule. Use templates/fitness-function-record.md for the operational record. Keep the ADR as the owner of the durable decision and its link to confirmation; keep implementation and execution in the project's test, CI, telemetry, or governance systems.

Completion and Boundaries

Complete when the requested ADR or review follows local conventions, identifies decision scope and authority without invention, preserves history, and distinguishes observed evidence from planned checks. If acceptance is unresolved, deliver a proposed record and name the missing decision rather than claiming acceptance.

When not to use

Route system-wide architecture and change sequencing to software-architecture, and named-tool implementation to the relevant operational skill. This skill owns decision rationale and confirmation links, not execution of the implementation or a general observability program.
