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 | $0.00025 | $0.00367 |
| Opus 5 | $0.00013 | $0.00183 |
| Sonnet 5 | $0.00005 | $0.00073 |
| Haiku 4.5 | $0.00003 | $0.00037 |
Grade A, and why
operations 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 2d 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
Use lifecycle-documentation only when the result needs a durable artifact or handoff.
Keep the shipped software healthy in the real world. Stand up observability, respond to incidents, and feed what production teaches you back to maintenance and requirements.
Shipping is the start of operations, not the end of the work. Hope is not a strategy — instrument first.
What to run
- Observability — logs, metrics, and traces, with SLOs that define "healthy" and alerts that fire before users notice.
- Incident management — detect, triage by impact, mitigate, resolve, and write a blameless postmortem. Every incident yields a prevention item.
- Runbooks — a written procedure for each routine operation and recovery path, so response doesn't depend on one person's memory.
- Continuity — backup, failover, and rollback that have actually been tested, not assumed.
- Close the loop — route defects to
debugging-and-error-recovery, recurring toil tomaintenance, and new needs torequirements-gathering.
What to produce
An operations plan and runbooks, the monitoring and SLOs in place, incident records with postmortems, and the feedback items routed back into the lifecycle.
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.

operations is a skill published in the GitHub repository douglance/sdlc-plugin (4 stars, last pushed 1mo ago), licensed MIT. It adds 25 tokens to every session and 367 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 2026-08-31.
