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 | $0.00093 | $0.04180 |
| Opus 5.5 | $0.00037 | $0.01672 |
| Sonnet 5.5 | $0.00019 | $0.00836 |
| Haiku 4.5 | $0.00009 | $0.00418 |
Grade A, and why
diagnostic-db-revisions 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 1mo 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 — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Diagnostic: Post Revision Analysis
You analyze WordPress post revision accumulation — how many revision records exist, which post types are generating the most revisions, whether revision capping is configured, and what database savings are available from setting or reducing a revision limit.
Overview
WordPress automatically saves a new revision every time a post is saved or autosaved. By default, there is no limit to how many revisions are stored — a post edited 500 times accumulates 500 revision rows in wp_posts. On active editorial sites, revision accumulation causes:
- Database bloat: Each revision stores a full copy of the post content, including post_title, post_content, post_excerpt, and metadata
- Slow query times: Larger
wp_poststables slow down post listing queries, especially in the admin panel - Backup size growth: Revision rows are included in database backups, increasing backup size and time
- Maintenance overhead: Manual cleanup requires identifying and deleting revision posts safely
Revisions do NOT affect frontend performance directly — they are filtered out of public queries by WordPress. The performance impact is indirect: larger wp_posts tables, slower admin queries, and inflated backups.
WP_POST_REVISIONS is the PHP constant that controls revision behavior. It can be set in wp-config.php to any of: an integer limit, true (unlimited), or false (disabled). If not defined, WordPress defaults to unlimited revisions. This skill checks the actual configured value and handles all four cases.
How It Works
Prerequisites
Before running checks, you need:
- Site connection profile from
sites.json(loaded by CoWork or /diagnose) WP_CLI_PREFIXset by the /diagnose command's Source-Type Routing sectionWP_CLI_AVAILABLE=true(this skill requires WP-CLI for all checks)
If WP_CLI_AVAILABLE is false, return a single Warning finding and stop.
Step 1: Dynamic Table Prefix Retrieval
Never hardcode wp_. Always retrieve the prefix dynamically before running any queries:
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.

diagnostic-db-revisions is a skill published in the GitHub repository dr-robert-li/cowork-wordpress-expert (29 stars, last pushed 8mo ago), licensed MIT. It adds 93 tokens to every session and 4,180 once invoked, about $0.0004 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.
