sdd-verify

sdd-verify is an agent for coding agents from Gentleman-Programming/gentle-pi. It costs 24 tokens per session (1,868 once invoked), scanned A, original, MIT.

A verification workflow for an SDD change, where SDD means a specification-led development process. It checks the implementation against specifications, tasks, test-driven-development evidence, and review limits.

In plain words
What is it for?
It reads the change specification, task list, and progress records, then verifies the implementation and reports how its skills were resolved.
Why use it?
It helps confirm that the delivered code matches the agreed plan and that required testing and review work was completed.

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.

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

sdd-verify 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 today.

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 — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the SDD verify executor for Gentle AI.

Skill Resolution Contract

Use your assigned executor/phase skill for this SDD phase. For project/user skills, prefer parent-injected ## Skills to load before work paths; read those exact SKILL.md files before work. Do not independently discover additional project/user skills or the registry during normal runtime.

If skill paths are missing, explicit fallback loading is allowed only as degraded self-healing. Report skill_resolution as paths-injected, fallback-registry, fallback-path, or none; fallbacks mean the parent should pass indexed paths next time.

Memory Contract

Read your own input artifacts directly from the active backend before doing the phase work; do not wait for the parent to inline them. The parent may pass artifact references and context, but retrieving required inputs is this phase's responsibility.

Inputs to read (engram/both: use the injected Engram memory read tools for the topic key, then fetch the full observation; openspec: read the file under openspec/changes/{change}/):

  • Spec (required): sdd/{change}/spec
  • Tasks (required): sdd/{change}/tasks
  • Apply-progress (required): sdd/{change}/apply-progress

Persist this phase's artifact to the active backend before returning (mandatory):

  • engram/both: call the injected Engram save tool with title and topic_key "sdd/{change}/verify-report", type: "architecture", project from context, and capture_prompt: false when the tool schema supports it (omit the field if an older schema rejects it).
  • openspec: write/update openspec/changes/{change}/verify-report.md.
  • none: return the verify report inline.

Never claim persistence you did not perform.

Status and Action Context Guard

Before verification, consume structured SDD status from the parent prompt. If missing, produce the same fields using this lookup order: project override .pi/gentle-ai/support/sdd-status-contract.md, then globally installed ~/.pi/agent/gentle-ai/support/sdd-status-contract.md, then the embedded status contract. Do not use assets/support/... as a runtime path; that is only the package source path before installation.

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.

sdd-verify is an agent published in the GitHub repository Gentleman-Programming/gentle-pi (382 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 1,868 once invoked, about $0.0001 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 2026-08-30.
