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 | $0.00012 | $0.03151 |
| Opus 5 | $0.00006 | $0.01576 |
| Sonnet 5 | $0.00002 | $0.00630 |
| Haiku 4.5 | $0.00001 | $0.00315 |
Grade B, and why
power-skills-diff scanned grade B with 1 finding 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 3d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

/fire-skills-diff - Compare Skill Versions
Compare two versions of a skill to see what changed between them.
Purpose
- Understand how a skill evolved
- Review changes before rollback
- Compare project vs global versions
- Audit skill modifications
- Learn from skill improvements
Arguments
| Argument | Required | Default | Description |
|---|---|---|---|
skill |
Yes | - | Skill path: {category}/{skill-name} |
v1 |
No | current | First version (base) |
v2 |
No | previous | Second version (compare) |
Usage Examples
# Compare current with previous version
/fire-skills-diff database-solutions/n-plus-1
# Compare two specific versions
/fire-skills-diff database-solutions/n-plus-1 1.0.0 2.0.0
# Compare current with specific version
/fire-skills-diff security/jwt-auth current 1.2.0
# Compare project vs global version
/fire-skills-diff api-patterns/pagination project global
# Side-by-side output
/fire-skills-diff performance/caching 1.0.0 2.0.0 --side-by-side
# Show only specific sections
/fire-skills-diff testing/snapshot --section "Code Example"
Process
Determine which versions to compare:
Default behavior:
v1= current (HEAD)v2= previous (HEAD~1)
Special keywords:
currentorhead= Latest versionpreviousorprev= One version before currentproject= Version in project libraryglobal= Version in global libraryX.Y.Z= Specific semantic version{commit-hash}= Specific git commit
# Resolve v1
if v1 == "current" or v1 == "head":
v1_ref = "HEAD"
elif v1 == "project":
v1_ref = "HEAD" (in project library)
elif v1 == "global":
v1_ref = "HEAD" (in global library)
else:
v1_ref = find_commit_for_version(skill, v1)
# Resolve v2 similarly
Fetch content for both versions:
cd ~/.claude/plugins/dominion-flow/skills-library
# Get v1 content
v1_content=$(git show {v1_ref}:{category}/{skill-name}.md)
# Get v2 content
v2_content=$(git show {v2_ref}:{category}/{skill-name}.md)
# For project vs global comparison
v1_content=$(cat ~/.claude/plugins/dominion-flow/skills-library/{category}/{skill-name}.md)
v2_content=$(cat ~/.claude/fire-skills-global/{category}/{skill-name}.md)
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.

power-skills-diff is a command published in the GitHub repository ThierryN/fire-flow (77 stars, last pushed 21d ago), licensed MIT. It adds 12 tokens to every session and 3,151 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
