Configuration: Read the internal documentation path from .prflow/config.json using: "${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}"/../../scripts/config-get.sh .docs.internal docs/internal/. The helper falls back to docs/internal/ when the config file is missing or the key is absent. Use the result as [[INTERNAL_DOC_LOCATION]] throughout this skill.

Portable helper anchor (single-statement). The bundled-helper commands in this skill spell the skill directory as ${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}. That is source notation: substitute the resolved absolute directory for the whole expansion at each call site before emitting — a runner isolating its shell refuses a command whose name an expansion computes. Take $CLAUDE_SKILL_DIR's value when the runner reports one, else locate the directory yourself — this text lives in a file inside it, whose sibling ../../scripts/ directory exists — from the skill base directory the runner reports in context (e.g. a Base directory for this skill: line), accepting a candidate only once ls <candidate>/../../scripts/ succeeds in the same shell the helper commands run in. If a path form is rejected, use the form that shell reports (pwd shows it); a Windows-form base directory (C:\...) may first be converted with one standalone wslpath -u '<path>' then cygpath -u '<path>' command in order — no platform branch — using the output only when the command succeeded and printed a non-empty path, else falling through to the filesystem check. Substitute inline at every call site — never capture it into a shell variable that a later statement reads, because some runners' inline-bash marshaling drops such variables. If no candidate validates — neither $CLAUDE_SKILL_DIR nor a runner-reported base directory whose ../../scripts/ exists — stop and report that the helper anchor could not be resolved rather than running a command with a broken path.

Consumer prompt extension (load first). Before doing this skill's work, load any consumer-supplied prompt extension for this skill and honor it. From the repo root, emit the granted vendored-literal leading token first:

.prflow/vendor/prflow/scripts/load-prompt-extension.sh docs-sync-internal

On a command not found / No such file / exit-127 reading (a checkout where .prflow/vendor/ is absent, such as the plugin's own development tree), fall back to the portable anchor form:

"${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}"/../../scripts/load-prompt-extension.sh docs-sync-internal

If the invocation fails because the helper path does not exist (No such file, exit 127, or the platform equivalent) on every form above, that is the anchor-resolution failure described in the Portable helper anchor note above — fix the anchor, don't report a missing extension. If instead the harness refuses the command outright — a permission denial rather than a missing file — the extension's state is unestablished: report that in the run's output and never treat it as a clean policy pass (unknown is not zero). Otherwise, if the helper exits non-zero, a consumer extension exists but could not be loaded — surface its stderr message and do not silently proceed as if none existed. If it exits 0 and prints text, treat that text as additional instructions appended to the end of this skill's own prompt for this run — it is upgrade-safe, consumer-owned customization committed under .prflow/skill-extensions/. If it exits 0 and prints nothing, proceed unchanged.
