What is hdd-stage-adr-brief?

A workflow for drafting a staging Architecture Decision Record (ADR), a document that records the context, chosen approach, hypotheses, and validation plan for a technical change.

Use it to create the next numbered staging ADR, record dependencies and conflicts, and check that its contents are complete.

It helps turn research into a complete, testable proposal before code is written.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 244 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00007	$0.00244
Opus 5	$0.00003	$0.00122
Sonnet 5	$0.00001	$0.00049
Haiku 4.5	$0.00001	$0.00024

Security

Grade A, and why

hdd-stage-adr-brief 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 4d 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

HDD Stage ADR Module

Inputs

task_goal
paths_to_inspect
acceptance_checks
hypotheses

Steps

Select next ADR number and staging filename.
Draft ADR sections: context, decision, hypotheses, validation plan.
Ensure each hypothesis is SOFT and directly testable.
Record dependency and conflict notes.
Validate ADR completeness against acceptance checks.

Outputs

status
summary
artifacts

Stop Conditions

Success: staging ADR exists and passes completeness checks.
Failure: ADR missing testability or essential constraints.
Escalation: numbering collision or unresolved dependency conflict.

Changes

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.
