hf.adr

hf.adr is a command for Claude Code from T-rav/hydraflow. It costs 0 tokens per session (472 once invoked), scanned A, original, Apache-2.0.

A command that records an architectural decision as a draft issue in HydraFlow, a project workflow system. It asks for a decision title and prepares the issue with its context, decision, consequences, and possible alternatives.

In plain words
What is it for?
Use it when deciding how a software system should be structured, such as choosing one source for queue counts or moving validation into a merge check.
Why use it?
It gives important design choices a consistent written record instead of leaving them in chat or memory. It also routes the draft to the repository and assigns the expected label and owner.

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

hf.adr 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 3d 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.

What it actually says

Create ADR Draft Issue

Capture an architectural decision as a draft ADR issue routed into HydraFlow.

Usage

/hf.adr Adopt a single source of truth for pipeline queue counts
/hf.adr Move visual validation into merge worker gate

$ARGUMENTS should be the ADR title suffix. If empty, ask for one.

Instructions

Phase 0: Resolve Configuration

Before creating anything, resolve:

  1. REPO: echo "$HYDRAFLOW_GITHUB_REPO"; if empty, use git remote get-url origin and parse owner/repo.
  2. ASSIGNEE: echo "$HYDRAFLOW_GITHUB_ASSIGNEE"; if empty, use repo owner.
  3. LABEL: Use hydraflow-find.

Never pass empty values to gh issue create.

Phase 1: Build ADR Issue

Create title: [ADR] <title from $ARGUMENTS>.

Create body with required sections:

## Context

<what problem/constraints drove this decision>

## Decision

<the concrete architectural decision>

## Consequences

<tradeoffs, follow-up work, operational impact>

Optional sections when relevant:

  • ## Alternatives considered
  • ## Related

Phase 2: Create Issue with gh

Use --body-file to avoid escaping issues:

BODY_FILE=$(mktemp)
cat > "$BODY_FILE" <<'ADR_EOF'
## Context
...

## Decision
...

## Consequences
...
ADR_EOF

gh issue create --repo "$REPO" \
  --assignee "$ASSIGNEE" \
  --label "$LABEL" \
  --title "[ADR] <title>" \
  --body-file "$BODY_FILE"

rm -f "$BODY_FILE"

Phase 3: Report Back

Return:

  • created issue URL
  • resolved repo/assignee/label
  • one-line ADR summary
  • confirmation it is queued for pipeline processing (triage -> plan/implement -> review)

Notes

  • ADR formatting is validated by HydraFlow ADR routing logic.
  • Use hydraflow-find so the issue is queued into the pipeline.
  • Keep decision text concrete and implementation-actionable.

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.
