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 | $0.00096 | $0.01624 |
| Opus 5 | $0.00048 | $0.00812 |
| Sonnet 5 | $0.00019 | $0.00325 |
| Haiku 4.5 | $0.00010 | $0.00162 |
Grade A, and why
narrating-cost-volumes 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 12d 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 — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Narrating Cost Volumes
Draft the cost volume narrative: the words that explain and justify the numbers. This skill writes the narrative and basis-of-estimate text around a cost model the user's pricing or finance team has built. It does not build the cost model and does not produce cost figures. Its job is to make the proposed costs understandable, credible, realistic, and consistent with the rest of the proposal.
When to use this skill
Use this skill once the pricing team has a cost estimate and the technical and management volumes are drafted, to write the cost volume narrative, the basis of estimate, and the cost-realism and reasonableness narrative, and to check that the cost volume agrees with the rest of the proposal.
It is not a pricing tool. It does not set rates, build cost models, or estimate
hours — those are the pricing team's work and the subject of
estimating-price-to-win on the strategy side.
Inputs
Required:
- The cost model and figures from the user's pricing team — labor categories, hours, rates, indirect rates, fee, ODCs, by CLIN and period.
- The solicitation's cost volume instructions (Section L) and cost evaluation criteria (Section M), and the Section B CLIN structure.
Preferred upstream artifacts:
12-sections/: the technical and management volumes, for the cost-technical consistency check.04-price-to-win.md: the price posture the bid is taking.10-compliance-matrix.md: the cost volume requirement rows.
Without the cost model, this skill cannot produce a cost volume. Ask the user for the pricing team's figures; do not generate cost numbers.
Read ../../shared/glossary.md, ../../shared/federal-solicitation-primer.md,
and ../../shared/pursuit-workspace.md if not already read this session.
Intake
Ask these as a numbered list. Skip what the solicitation answers.
- The cost model. What are the proposed costs, by CLIN and period — labor categories, hours, direct rates, indirect rates, fee, escalation, ODCs? Who on the pricing team owns them?
- Cost volume instructions. What does Section L require — format, CLIN structure, supporting detail, a separate basis of estimate, cost element breakdowns, the page or file rules?
- Cost evaluation. How does Section M evaluate cost or price — reasonableness, realism (cost-reimbursement), total evaluated price, options? Is this best-value or LPTA?
- Contract type. FFP, T&M, cost-reimbursement, or hybrid? (This governs how much cost detail and realism narrative is needed.)
- Cost-technical link. Are the technical and management volumes drafted, so the cost volume can be checked against the staffing and approach they propose?
What ships with it
2 files 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.

narrating-cost-volumes is a skill published in the GitHub repository danielkinneyspears/federal-proposal-skills (5 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 96 tokens to every session and 1,624 once invoked, about $0.0005 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.
