BD file-writer
Safe file writing strategy for large files. Use when you need to write or update large files (over 5000 bytes) to avoid truncation. Provides step-by-step approach: (1) Read current state, (2) Use edit tool for precise modifications, (3) Verify results, (4) Repeat until complete. Also provides fallback strategies and error recovery.
Safe file writing strategy for large files.
As a process D 49/100 · Unfinished process — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- 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.

Process rating: all ten parameters 49/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 4 mutating operations with no state check
- 40Result and completion. Does not say what the result is
- 40Consistency. Frontmatter name (file-writer) differs from the folder (file-writer-safe)
- 50Failures and branches. 0 branches, has a failure section
- 60Tools and files. Uses tools (read) that frontmatter does not declare
- 100Steps. 46 steps
- 100Execution cost. Instruction body is 1797 tokens
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
- +1No license
- +2Single-language instructions
- +3Description length 333: enough signal without eating the budget
- +4Structure: 26 headings
- +3Step-by-step instructions: 46 items
- +4Has examples (11 code blocks)
Quality base 70; lint remarks subtract, signals add up to 100. Result: 74.
