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.

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 | $0.00045 | $0.01801 |
| Opus 5 | $0.00023 | $0.00901 |
| Sonnet 5 | $0.00009 | $0.00360 |
| Haiku 4.5 | $0.00005 | $0.00180 |
Grade A, and why
openspec-superpowers 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 5d 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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenSpec <-> Superpowers Bridge
This skill orchestrates the SDD-TDD workflow by connecting OpenSpec's artifact pipeline to Superpowers' execution skills. It supports four modes: plan, run, verify, and archive.
Mode: plan
Purpose: Create implementation-plan.md from the sdd-tdd schema template.
Skill dependency: superpowers:writing-plans
Instructions
- Read the current change's
tasks.mdviaopenspec instructions implementation-plan --change <change>. - Activate the
superpowers:writing-plansskill. - Investigate the codebase before writing anything. Read the modules the change touches, confirm build/test/lint commands, note conventions (naming, base classes, route prefixes, DTO patterns) and missing prerequisites (dependencies, config). Record these under "Key facts for implementers" in the plan. A plan written without reading the code is fiction.
- Generate
implementation-plan.mdin the change directory, following the schema template structure exactly -- including its embedded generation rules. - Map every unchecked OpenSpec task ID from
tasks.mdto exactly one plan step. If any task is unmapped, the plan is incomplete -- do not proceed. - Do NOT check off
tasks.mdcheckboxes during planning. Task completion happens only inrunmode.
Quality bar (from superpowers:writing-plans)
The plan must be executable by an engineer with zero context for this codebase who cannot ask questions. Concretely, every step contains:
- Complete, copy-pasteable code -- the actual test and the actual implementation, with imports. Never a description of code.
- Exact file paths from the repo root, marked (create) or (modify).
- Exact commands with expected output -- the RED command with the exact expected failure (assertion message or error type), the GREEN command expecting pass, and a commit command.
Anti-patterns that mean the step must be rewritten, not patched:
- Prose standing in for code: "add validation logic", "wire up the controller", "handle the error case"
- Placeholders:
// TODO,// implement here,..., "similar to Step N" - Commands without expected outcomes: "run the tests" with no stated failure/pass criteria
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.

openspec-superpowers is a skill published in the GitHub repository kxdds/sdd-tdd (1 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 1,801 once invoked, about $0.0002 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 2026-08-31.
