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 | $0.00143 | $0.00779 |
| Opus 5 | $0.00072 | $0.00390 |
| Sonnet 5 | $0.00029 | $0.00156 |
| Haiku 4.5 | $0.00014 | $0.00078 |
Grade A, and why
fcs-reconcile 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 10d 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.
What it actually says
fcs-reconcile（对账）
本 Skill 是工具集安全、输出与质量标准的参考实现。确定性对账引擎已实现（v0.3.0，发布状态 Preview）。
何时使用 / 不使用
- 应触发：银行流水 vs 收付款台账对账；应收与回款核对；应付与付款核对；两个业务系统交易明细核对。
- 不应触发：生成报表（→ 未来
fcs-report）、数据清洗（→fcs-clean）、凭证过账、税务/会计政策结论、需联网登录外部系统的任务。
数据处理声明（运行前须向用户展示并确认）
运行模式：本地隔离
将读取：N 个本地文件 ｜ 将写入：M 个结果文件
原始数据进入模型：否
网络访问：已禁用
源文件修改：否
终端输出交易明细：否
输入完整性：读取前后 SHA-256 校验
使用流程
- 用户选择左表（业务台账）与右表（银行流水/对方系统）。
- 运行前确认字段映射、匹配规则、容差、输出位置与隐私运行模式（见 docs/contracts/fcs-reconcile/input-contract.md）。
- 本地程序执行对账（
scripts/reconcile.py）。 - AI 只接收汇总结果（匹配率、各状态计数、勾稽结论），原始明细留本地。
- 生成结果工作簿与运行清单，用户复核并保存。
核心约束（不可退让）
- 只有候选唯一且规则完全满足时才自动确认（误判率 0，NFR-01）。
- 容差只用于差异分级，不放宽自动确认（技术设计 §5.3）。
- 金额一律
Decimal，不参与浮点运算。
关键规则与术语
- 匹配阶段与自动确认铁律：见 references/matching-rules.md。
- 中文财务术语与字段释义：见 references/field-glossary.md。
运行
python scripts/reconcile.py --config <config.yaml>
配置字段（字段映射、match.primary_key / match.composite_keys / amount_tolerance /
date_tolerance_days / direction_rule、output.path）见
docs/contracts/fcs-reconcile/input-contract.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.
- 10d ago First seen · 60 lines · 143 tokens per session scan A cd4898ceb6b8
fcs-reconcile is a skill published in the GitHub repository cxtx/finance-copilot-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 143 tokens to every session and 779 once invoked, about $0.0007 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.
