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 5.1 | $0.00115 | $0.01071 |
| Opus 5 | $0.00057 | $0.00535 |
| Sonnet 5 | $0.00023 | $0.00214 |
| Haiku 4.5 | $0.00012 | $0.00107 |
Grade A, and why
sdlc-guided 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 7d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
sdlc-guided
The doorway into the human-in-the-loop agentic-sdlc flow. On hosts like Codex
that have skills but no commands, this stands in for the retired sdlc:start
command.
Stay a doorway
A doorway that starts doing the work is no longer a doorway, and a run whose artifacts were half-written before Phase 0 cannot be reasoned about. So this skill reads intent and delegates; it does not touch the repository.
Specifically, nothing here may:
- Make
docs/superpowers/runs/<run-id>/, or any other run or task directory. - Write
meta.json,requirements.md,complexity.json,design.md,plan.md,events.jsonl,decisions.jsonl,work-item.md, or any ledger. - Do a phase's work early — no intake, no sizing, no brainstorming, no planning, no branch guard, no building, no QA, no status repair.
- Improvise
sdlc-enginebecause the host would not invoke it.
That last one is the tempting failure. If sdlc-engine cannot be reached,
say startup is blocked and stop there. A hand-rolled approximation looks
helpful and leaves behind artifacts nothing downstream can trust. Ownership of
every artifact starts inside sdlc-engine Phase 0, and not one step sooner.
When the project owns implementation
Read .agentic/agentic-sdlc/config.json before delegating. If it names project orchestrators, pass their
routing contract through to sdlc-engine: this package still owns intake,
planning, QA and the delivery handoff, while implementation is delegated once to
the orchestrator the project selected. Fleet workers are never called directly —
going around the project's own orchestrator is how two pipelines end up believing
they own the same change.
Inputs
raw_input— whatever the user is asking for: prose, a tracker reference, or a path to a story filemode_flag—--greenfieldwhen starting from nothing, otherwise unsetescalate_on— risk flags that force a human decision; defaults to["security", "breaking-change"]
Usage Examples
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

sdlc-guided is a skill published in the GitHub repository Jarroslav/agentic-os (0 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 115 tokens to every session and 1,071 once invoked, about $0.0006 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.
