Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00024 | $0.00574 |
| Opus 5.5 | $0.00010 | $0.00230 |
| Sonnet 5.5 | $0.00005 | $0.00115 |
| Haiku 4.5 | $0.00002 | $0.00057 |
Grade A, and why
version scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Show the installed ai-sdlc plugin version, the latest published version on
the marketplace, and whether the install is up to date. Bypasses the 24h
cache used by the SessionStart staleness nag (AISDLC-89) — every run
re-fetches marketplace.json from main.
When to run this
- After you've ignored the SessionStart nag for a few sessions and want to re-check whether you're still behind.
- After running
/plugin update ai-sdlc && /reload-plugins, to confirm the install actually advanced. - When debugging "why doesn't
/<some-feature>work?" — the answer is often that the plugin is older than the documented version.
Output
ai-sdlc plugin
- Installed: v0.8.1
- Latest: v0.8.1
- Last checked: just now
- Status: ✓ up to date
When stale:
ai-sdlc plugin
- Installed: v0.7.0
- Latest: v0.8.1
- Last checked: just now
- Status: ⚠ stale — run /plugin update ai-sdlc && /reload-plugins
When the marketplace can't be reached:
ai-sdlc plugin
- Installed: v0.8.1
- Latest: unknown (fetch failed)
- Status: ? could not reach marketplace.json
Implementation contract
Run the version-check hook in print mode and surface its output verbatim:
node "${CLAUDE_PLUGIN_ROOT}/hooks/check-plugin-version.js" --print
The hook respects AI_SDLC_DISABLE_VERSION_CHECK=1 — if the operator has
opted out of the SessionStart nag, this command will print
ai-sdlc plugin version check disabled (AI_SDLC_DISABLE_VERSION_CHECK=1)
and exit. That's intentional — opt-out is opt-out across both surfaces.
Notes
- This command never mutates the install. To actually update, run
/plugin update ai-sdlc && /reload-plugins. Last checkedreflects the cache freshness AFTER this command refreshes it — so it always says "just now" on a successful fetch.- Network failures don't fail the command. They just report
Status: ? could not reach marketplace.json.
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.

version is a command published in the GitHub repository ai-sdlc-framework/ai-sdlc (415 stars, last pushed yesterday), licensed Apache-2.0. It adds 24 tokens to every session and 574 once invoked, about $0.0001 per session on Opus 5.5. 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.
