PoseCap: Skill for Codex

.agents/skills/ad-adr/SKILL.md

ad-adr is a skill for Codex from CorridorTech/PoseCap. It costs 69 tokens per session (818 once invoked), scanned A, original, Apache-2.0.

A written record of one software architecture decision, including its context, chosen approach, effects, and rejected alternatives.

In plain words
What is it for?
Use it to draft a proposed decision document in the repository's doc/adr folder.
Why use it?
It preserves why a technical choice was made so future developers do not have to reconstruct the reasoning.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is CorridorTech/PoseCap's own configuration. It tells Codex how to work on PoseCap 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 PoseCap configures →

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 attempts to fill the context window with filler content, displacing legitimate instructions and safety constraints. This can degrade agent performance or bypass safety boundaries.
    Fix: Implement context-window management that detects and rejects padding or stuffing attempts. Prioritize system instructions over user-injected content.

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

ad-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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<background_information> Drafts doc/adr/NNNN-<short-title>.md for one architecture decision. Status lifecycle: proposed → accepted → deprecated | superseded by ADR-NNNN. </background_information>

Step 2 — confirm scope. The ADR captures one decision. If the user's request implies multiple, ask which to write first; the others become follow-up ADRs.

Step 3 — fill from conversation only. Use the template below. Fill Context, Decision, Consequences, and Alternatives Considered from this conversation only — no fabrication. If a section has no signal, ask one question per gap.

Decision must be a directive ("We will…"), not a description. Consequences lists positive and negative; do not balance for the sake of balance. Alternatives Considered lists each rejected option with a one-line reason.

Step 4 — write the file. Path: doc/adr/<NNNN>-<short-slug>.md. Slug: kebab-case, ≤6 words. Status: proposed. Date: today, ISO format. Deciders: ask the user.

Stop after writing. Do NOT flip status to accepted — that requires user review.

Status: <proposed | accepted | deprecated | superseded by ADR-NNNN> Date: <YYYY-MM-DD> Deciders: <names or roles>

Context

<What is the issue motivating this decision? What forces are at play — technical, organizational, regulatory, cost?>

Decision

<State as a directive: "We will…". One decision per ADR.>

Consequences

<What becomes easier, harder, or different. List positive, negative, and neutral consequences.>

Alternatives Considered

  • <option> — <why rejected>
  • <option> — <why rejected>

<output_contract> A single new file at doc/adr/<NNNN>-<short-slug>.md. Status proposed. No existing ADRs modified. No invented content.

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.
