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 | $0.00084 | $0.00783 |
| Opus 5 | $0.00042 | $0.00392 |
| Sonnet 5 | $0.00017 | $0.00157 |
| Haiku 4.5 | $0.00008 | $0.00078 |
Grade A, and why
software-pricing 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 8d 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Pricing (CostBench)
Query verified, sourced software-pricing intelligence for 3,290+ products using the free CostBench service. No account or API key required. Data is read-only and every figure carries its source and date.
Decision order
- If CostBench MCP tools are available (
costbench:get_pricing,costbench:compare_software, etc.) — use them directly. Products are addressed byslug(e.g.salesforce,microsoft-teams,openai-api). - Otherwise, use the bundled script (requires network access to costbench.com):
scripts/pricing.sh get_pricing salesforce
scripts/pricing.sh compare_software slack,microsoft-teams
scripts/pricing.sh discover_software category=crm maxPrice=50
The script path is relative to this skill's directory. It calls the hosted MCP endpoint over plain HTTPS and prints the JSON result.
Tools
| Tool | Use it for |
|---|---|
get_pricing |
Full sourced record: tiers, hidden costs, contract terms, negotiation tips, price history. Args: slug, optional depth (summary|full). |
get_hidden_costs |
Just the documented hidden/implementation/add-on fees. Args: slug. |
get_negotiation_tips |
Sourced negotiation tactics with success-likelihood. Args: slug. |
get_price_history |
Per-quarter price snapshots + trend — did the price change? Args: slug. |
compare_software |
Side-by-side of 2–4 products. Args: slugs (array). |
discover_software |
Find products by category, maxPrice, hasFreeTier. |
calculate_tco |
True multi-year cost for a team. Args: slug, seats, optional tier, termYears. |
estimate_llm_cost |
Cost of an LLM/API workload from a real rate card. Args: slug, inputTokens, outputTokens, optional model. |
Finding the slug
If you don't know a product's slug, use discover_software with a category, or try the obvious kebab-case of the product name (microsoft-teams, google-workspace, openai-api). get_pricing returns a "No product found" message if the slug is wrong.
What ships with it
1 file 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.

software-pricing is a skill published in the GitHub repository aadilr/costbench-mcp (0 stars, last pushed 14d ago), licensed MIT. It adds 84 tokens to every session and 783 once invoked, about $0.0004 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.
