Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Fill a placeholder — infer the best content from surrounding context.Key capabilities
- →Infers content for placeholder tags
- →Analyzes surrounding context for generation
- →Resolves external resource references
- →Supports scope modifiers for precise filling
How it works
It reads the surrounding text and any referenced resources to generate content that fits naturally into the specified placeholder position.
Inputs & outputs
When to use ph
- →Generating transition sentences
- →Filling documentation stubs
- →Updating code placeholders with context-aware content
About this skill
Placeholder
Activation Boundary
This is a tag-only worker skill. Use it only after execute or execute-one
selects an exact <@ph...> annotation in a target document and hands off its
context. Never activate it from ordinary chat, semantic similarity, or any
skill other than those two routers. Without that handoff, produce no
placeholder and direct the user to add the tag and run a router.
Generate content that fits naturally at the tag position and replace only the tag with it.
Tag
<@ph>
<@ph: hint about what to fill>
Example: We evaluated <@ph: the number of participants> participants.
Input
- File path — the document being processed.
- Surrounding block — the maximal run of non-blank lines containing the tag; blank lines bound it.
- Prompt (optional) — a hint (for example "a transition sentence"). Default: infer from context.
Workflow
- Read the text before and after the tag; read the full file if broader context helps.
- Generate content that fits naturally at that exact position in tone, style, and meaning.
- Write the result back: replace ONLY the
<@ph>tag with the generated text. All surrounding text stays untouched.
Scope Modifiers
<@ph> never modifies surrounding content, so modifiers mainly provide
context:
- Protect
<< >>— context only; never modify. This skill does not remove protect delimiters outside its own insertion. - Field
(( ))— when the tag sits inside a field, generate content that belongs in that field.
Context References
Double-backtick references in the prompt point to resources that inform the
generated content (for example <@ph: a summary based on ``results.md``>).
Resolve paths relative to the document's directory unless absolute.
Rules
- The output must read as if it had always been part of the text; keep it concise and contextually appropriate.
- Replace only the selected annotation. Preserve every unrelated annotation,
<@comment: ...>tag,<@chat-model>block, and contextual literal/example byte-for-byte. - On any error (for example an unreadable referenced file), fail cleanly: leave the tag, change nothing, report.
When not to use it
- →When the placeholder lacks sufficient surrounding context
- →When the user wants to manually define the content
Limitations
- →Depends on context quality
- →Requires removal of tags and modifiers
How it compares
It uses context-aware inference to fill placeholders rather than simple template substitution.
