BD session-compactor
上下文压缩技能。当对话越来越长、token快爆的时候，自动压缩旧消息为摘要，保留最近上下文。 触发条件： - "压缩会话"、"compact"、"上下文满了" - 检测到消息超过阈值（默认100条或token估计超过80000） - 手动调用 $compact 无外部依赖，纯Node.js实现。
As a process D 41/100 · Unfinished process — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
For the model run — optional
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec
- warning
description-no-whendescription does not say WHEN to use the skill (no "use when")
Process rating: all ten parameters 41/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 40Consistency. Frontmatter name (session-compactor) differs from the folder (dragon-session-compactor)
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 100Steps. 8 steps
- 100Execution cost. Instruction body is 677 tokens
- 100Running it twice. No mutating operations
- low 10 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
Quality signals
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
- +3Output format is not stated: the model decides each time
- -5TODO / placeholder text left in the skill
- -31 of 2 scripts are never mentioned in SKILL.md
- +1No license
- +2Single-language instructions
- +3Description length 148: enough signal without eating the budget
- +4Structure: 16 headings
- +3Step-by-step instructions: 8 items
- +4Has examples (10 code blocks)
Quality base 70; lint remarks subtract, signals add up to 100. Result: 64.

This is a local session-compaction skill whose sensitive behavior is disclosed and aligned with its purpose, but users should be careful because it persists and rewrites conversation history.
