knowledge-resume

Knowledge Resume

Give the user a fast, grounded status view of a cogni-knowledge base so they know what is inside and what the right next action is. This skill is read-only with respect to the binding and the wiki — it never writes. The only side effect is that the native health.py invocation appends its health-check log line to wiki/log.md (the same side effect the old cogni-wiki:wiki-resume dispatch produced — unchanged).

Read ${CLAUDE_PLUGIN_ROOT}/references/delegation-contract.md once at the start of a session so you remember the wiki-engine boundary — cogni-knowledge computes the wiki health verdict on the vendored wiki-health engine (resolved vendored-first), it does not dispatch cogni-wiki:wiki-resume.

When to run

• User asks for status, overview, or "where was I" on a knowledge base
• User returns after a gap and wants orientation
• Right after knowledge-setup or a knowledge-finalize run finished, to confirm the deposit and suggest the next step
• Proactively when a session opens in a directory containing .cogni-knowledge/binding.json

Never run when

• A specific target was named (--knowledge-slug, or a --knowledge-root pointing at one base) and that target directory has no .cogni-knowledge/binding.json — abort and offer knowledge-setup instead (Step 1, point 2). This is the narrow named-but-unbound case, not the no-target case: when no --knowledge-slug is given the skill legitimately runs to print the Step 0.5 discovery menu, whose empty-discovery sub-case is itself where the start-a-new-base / knowledge-setup affordance is now offered.

Parameters

Parameter	Required	Description
--knowledge-slug	No (conditional)	Slug of the knowledge base to resume. Resolves to cogni-knowledge/<slug>/ unless --knowledge-root overrides. When omitted (and --knowledge-root does not point at a single bound base), the skill runs the Step 0.5 discovery menu — listing the bound bases plus a peer "start a new base" offer — instead of resuming a single target.
--knowledge-root	No	Override the default knowledge-base directory.
--verbose	No	Includes the last 10 wiki/log.md entries verbatim (default: last 3).

Workflow

0. Pre-flight

Required engine. This skill computes the wiki health verdict on the vendored wiki-health engine — cogni-knowledge ships a byte-identical copy in-tree under scripts/vendor/cogni-wiki/, so a bound base shows its resume status without cogni-wiki installed and this skill no longer dispatches cogni-wiki:wiki-resume, mirroring the native posture of knowledge-dashboard and knowledge-query. It reads the inverted-pipeline manifests via pipeline-summary.py and never reaches cogni-research. The cogni-wiki install is only a fallback layout. Probe both so the skill aborts cleanly here rather than failing mid-skill:

# vendored-first: the in-tree wiki-health scripts are self-contained
test -d "${CLAUDE_PLUGIN_ROOT}/scripts/vendor/cogni-wiki/skills/wiki-health/scripts" && WIKI_OK=yes || WIKI_OK=no

# fallback: an installed cogni-wiki sibling / marketplace cache (legacy layout)
if [ "$WIKI_OK" = "no" ]; then
  probe_plugin() {
    local plugin="$1" skill="$2"
    test -f "${CLAUDE_PLUGIN_ROOT}/../${plugin}/skills/${skill}/SKILL.md" && return 0
    for d in "${CLAUDE_PLUGIN_ROOT}/../../${plugin}/"*/skills/"${skill}"/SKILL.md; do
      [ -f "$d" ] && return 0
    done
    return 1
  }
  probe_plugin cogni-wiki wiki-setup && WIKI_OK=yes || WIKI_OK=no
fi

If WIKI_OK is no, abort:

cogni-knowledge's vendored wiki-health scripts are missing and no cogni-wiki install was found. Reinstall cogni-knowledge, then retry.

Resume is read-only with respect to disk; the vendored-first probe gives the user the same clean signal every other knowledge-* read/render skill emits. This probe is the early-abort gate only — Step 2's resolve_wiki_scripts is the authoritative resolver for the actual health.py path; keep the two vendored-first precedences in sync.

0.5. Discovery — resolve the target base (no clear target → present bases + offer a new one)

Resume is the natural orientation front door: the moment a session opens is the moment a user either continues prior work or starts new work. So when the invocation gives no clear single target, do not abort — present what exists and the start-a-new affordance as peers, then stop for the user to choose. This step is read-only (a Glob + per-base knowledge-binding.py read, no writes), consistent with the rest of the skill.

When a clear target IS given, skip this step and go straight to Step 1. A clear target is either: --knowledge-slug is set, OR --knowledge-root is set and points at a single base (its own .cogni-knowledge/binding.json exists). In both cases there is exactly one base to resume — Step 1 resolves it as before.

When no clear target is given (no --knowledge-slug, and --knowledge-root is absent or points at a parent directory holding multiple bases):

1. Resolve the search root. If --knowledge-root is set, use it as the search root; otherwise use cogni-knowledge/ relative to the current working directory.

2. Discover the bound bases. Glob <search-root>/*/.cogni-knowledge/binding.json. For each hit, read its binding fail-soft (an unreadable / malformed binding is omitted, never aborts the scan):

   python3 ${CLAUDE_PLUGIN_ROOT}/scripts/knowledge-binding.py read \
       --knowledge-root <hit-parent-dir>
   

   Capture knowledge_slug, knowledge_title, and created from each successful read.

3. Present the menu — bases AND a peer "start a new base" entry. Print a numbered list of the discovered bases (knowledge_title · <slug> · created <date>), then one final peer entry:

   Bound knowledge bases under <search-root>/:
     1. <knowledge_title> · <slug> · created <date>
     2. <knowledge_title> · <slug> · created <date>
     …
     N. Start a new base — run `knowledge-setup` to bootstrap one.
   
   Resume an existing base with `knowledge-resume --knowledge-slug <slug>`,
   or start a new one with `knowledge-setup`.
   

   Then stop — do not enter Step 1. Resume is read-only, so the menu is a presented suggestion, not an interactive dispatch (the skill has no AskUserQuestion); the user re-invokes with the slug they pick, or runs knowledge-setup.

4. Empty-discovery sub-case (the Glob found no bound base under the search root): print

   No bound knowledge bases found under <search-root>/.
   Run `knowledge-setup` to bootstrap your first base.
   

   Then stop. This is the no-target home of the start-a-new-base affordance (the named-but-unbound case stays in Step 1, point 2).

1. Resolve the knowledge root and read the binding

This step runs only on the slug-resolved path — --knowledge-slug was supplied, or Step 0.5 resolved a single clear target. (A no-target invocation never reaches here; Step 0.5 prints the discovery menu and stops.)

1. Resolve knowledge_root:

   • If --knowledge-root is set, use it.
   • Otherwise, knowledge_root = cogni-knowledge/<knowledge-slug>/ (relative to the current working directory).

2. Read the binding:

   python3 ${CLAUDE_PLUGIN_ROOT}/scripts/knowledge-binding.py read \
       --knowledge-root <knowledge_root>
   

   On success: false, abort and offer knowledge-setup. Do not auto-create.

3. Extract from the binding: knowledge_slug, knowledge_title, wiki_path, research_projects[], created, and the charter (binding.get("charter", {}).get("domain"/"audience"/"scope", "") — schema 0.1.4; the .get chain falls through to "" on a pre-0.1.4 binding, read-only fail-soft). (The bound wiki's own slug, if needed for display, comes live from <wiki_path>/.cogni-wiki/config.json — never cached in the binding.)

   Then read the topic lineage for display via the themes subcommand (don't render open_themes[] from the raw binding — a researched seed is never pruned out of it; themes partitions it against covered_themes[] at read time):

   python3 ${CLAUDE_PLUGIN_ROOT}/scripts/knowledge-binding.py themes \
       --knowledge-root <knowledge_root>
   

   Capture open_active (still-open seeds, researched ones already dropped) and covered (each {label, question_slug}, where label is already the labels[0]-with-question_slug-fallback render). Read-only and fail-soft (structurally-invalid / pre-0.1.4 binding → empty lists, success: true).

4. When --knowledge-slug was supplied, validate the binding's knowledge_slug matches it. Mismatch → abort. (On the --knowledge-root-resolved single-base path there is no slug to match against — skip this check and take the binding's own knowledge_slug as authoritative.)

2. Compute the wiki status natively (vendored health.py + direct reads)

Resolve the vendored wiki-health scripts dir vendored-first (the same resolve_wiki_scripts posture knowledge-dashboard / knowledge-ingest use), then invoke health.py directly — no Skill dispatch:

. "${CLAUDE_PLUGIN_ROOT}/scripts/resolve-wiki-scripts.sh"
WIKI_HEALTH_SCRIPTS=$(resolve_wiki_scripts wiki-health health.py) \
  || abort "cogni-wiki wiki-health scripts not found (vendored copy missing)"

2a. Health verdict. Run the vendored health.py against the bound wiki (it resolves _wikilib itself; read-only apart from the health-check log line it appends — the same side effect the old dispatch produced):

python3 "${WIKI_HEALTH_SCRIPTS}/health.py" --wiki-root "<wiki_path>"

Parse the JSON envelope and capture data.errors, data.warnings, and data.stats (entries_count_actual, entries_count_drift, claim_drift_count). The one-line verdict for Step 3 is OK when errors is empty, else N issues — <first error class(es)>; surface entries_count_drift / claim_drift_count as warnings when non-zero. Also scan data.warnings[] for the structural-drift finding classes the detect child emits — structural_drift (a curated front-door region, the OVERVIEW-NARRATIVE placeholder or an empty ROOT-LINKS sentinel, left unpopulated on a >= 0.0.8 base) and schema_version_lag (config schema_version trails the engine's current schema) — and capture whether either class is present. These are warnings, not errors, so a drifted >= 0.0.8 base still reads a bare OK verdict; the Step 3 repair branch therefore keys on the captured class, not on the verdict. Fail-soft: an absent or unparseable warnings[] leaves both flags unset and the repair branch is skipped (never block resume on a warnings read — the parallel of the schema_version fail-soft posture below). On success: false (e.g. <wiki_path>/.cogni-wiki/config.json absent), surface the error and still print the binding section per Edge cases.

2b. Context brief + recent log (direct reads). Read the wiki's own orientation surfaces directly — both fail-soft (a missing file is omitted, never an abort). Resolve each path through the control-file resolver (legacy wiki/<file> today, wiki/meta/<file> once the layout flip lands — prefers wiki/meta/ when present) rather than hardcoding it:

• CONTEXT_BRIEF=$(python3 "${CLAUDE_PLUGIN_ROOT}/scripts/control-path.py" context-brief --wiki-root "<wiki_path>"), then Read "$CONTEXT_BRIEF" (auto-rebuilt by ingest/finalize) for the one-paragraph summary.
• LOG_PATH=$(python3 "${CLAUDE_PLUGIN_ROOT}/scripts/control-path.py" log --wiki-root "<wiki_path>"), then Read "$LOG_PATH" for recent activity — show the last 3 lines by default, the last 10 when --verbose is set.
• Entry count comes from <wiki_path>/.cogni-wiki/config.json (entries_count), cross-checked against data.stats.entries_count_actual from 2a. Capture schema_version from the same config read — the Step 3 decision tree branches on it (health.py does not surface it).

For each deposited project (cap at 5, newest first), read its inverted-pipeline depth so the summary shows how far each project got, not just that it exists:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/pipeline-summary.py project \
    --project-path <research_projects[i].project_path>

Capture sub_questions, fetched, phase_reached, and the distill fields concepts_total / claims_attached / claims_deduped. Legacy deposits (no .metadata/ manifests) return zeros + phase_reached: "none" — render their depth as (legacy deposit) rather than 0 sub-questions. Then read the knowledge-base-global fetch-cache verdict once:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/pipeline-summary.py cache-health \
    --knowledge-root <knowledge_root>

Capture verdict (and entries).

3. Compose the cogni-knowledge summary

Print a ≤ 12-line summary that layers the binding onto the wiki status:

• Knowledge base. <knowledge_title> (<knowledge_slug>), created <created>
• Charter. When charter.domain is non-empty (schema 0.1.4): <charter.domain> · for <charter.audience> · scope <charter.scope>. Omit the line entirely on a pre-0.1.4 / unframed base. When the charter is set, append a one-line read-only re-steer offer beneath it: "Re-steering the base? Run knowledge-setup --reframe --knowledge-slug <slug>." This is a suggestion only — resume stays read-only (the re-frame write lives in knowledge-setup, never here).
• Wiki path. <wiki_path> — wiki health verdict from Step 2a (one line: "OK" / "N issues — <first error class(es)>"; append a · entries drift <±N> / · claim drift <N> note when those stats are non-zero, and a · structural drift / · schema lag note when the Step 2a structural_drift / schema_version_lag warning class is present — paralleling the drift suffixes so a degraded front door is visible even when the verdict is a bare "OK")
• Deposited research projects. <count> — one line per project (newest first, cap 5, "and N more" for the rest), each as: <slug> — <sub_questions> sub-questions · <fetched> fetched · phase <phase_reached> + · <concepts_total> concepts (<claims_deduped>/<claims_attached> claims deduped) when concepts_total > 0 (the Phase-4.5 distill compounding signal) + · synthesis ✓ when the binding entry's report_source == "wiki" + (<deposited_at>). Legacy deposits show <slug> — (legacy deposit) (<deposited_at>).
• Pipeline status. Knowledge-base-global fetch-cache (one shared cache across all projects): one line by verdict — healthy → fetch-cache healthy (<entries> sources); stale → fetch-cache stale — re-run knowledge-curate to re-fetch aged sources (or knowledge-refresh to re-run the pipeline on stale topics); empty → fetch-cache empty — run knowledge-plan first.
• Topic lineage. Use the themes subcommand output from Step 1. If covered or open_active is non-empty, print them as two short lists: render the covered list from covered[] (each entry's label — already the labels[0]-with-question_slug-fallback render; never the raw object or the theme_key), and the open list from open_active (plain strings — the still-open seeds, with researched seeds already dropped off so the backlog tracks reality). Else omit.
• Next action. One line, selected by the decision tree below.

The Step 2 health detail (the verdict line plus any errors/warnings worth surfacing, the context-brief summary, and the recent-log lines) appears above the summary so the user has the structural detail at hand; cogni-knowledge's contribution is the binding overlay.

Next action — recommend by pipeline phase

Pick the one Next-action line to print by branching on workflow state, not by reading out a fixed sequence. The state field is each project's phase_reached from pipeline-summary.py project (none → plan → curate → fetch → ingest → distill → compose → verify); a finalized project has report_source == "wiki" in its binding entry (the · synthesis ✓ marker). Evaluate top to bottom and stop at the first match:

• Wiki has structural issues (Step 2a verdict ≠ OK): "Fix the structural issues first — see the health detail above; run knowledge-lint --fix=all to repair the mechanical drift classes (a separate operator-invoked write step — resume never auto-fixes), or knowledge-health for a deeper read-only structural verdict. Then resume the pipeline, or knowledge-query --knowledge-slug <slug> --question '...' to ask what the base already knows."
• Base predates the curated layout (Step 2b schema_version < 0.0.8 — compare as dotted integer tuples, e.g. (0,0,10) > (0,0,8), never as strings): "Migrate this base to the curated layout — run knowledge-index --migrate --knowledge-slug <slug> (dry-run preview first; add --apply to execute). Control files move under wiki/meta/, the overview folds into the index intro, and the flat root splits into root-map + per-type sub-indexes." Suggestion only — resume never runs the migration (the write lives in knowledge-index, mirroring the charter re-steer posture). A missing or unparseable schema_version skips this branch (never block resume on a version read — the parallel of the existing fail-soft posture).
• Curated front door has drifted (Step 2b schema_version >= 0.0.8 AND Step 2a flagged a structural_drift or schema_version_lag warning class): "Regenerate the drifted front-door regions — run knowledge-index --repair --knowledge-slug <slug> (dry-run preview first; add --apply to execute). It re-renders the theme-scoped ROOT-LINKS region and reconciles a lagging schema_version to the engine's current schema; a stale overview narrative is re-authored as part of that same knowledge-index --repair run." Suggestion only — resume never runs the repair (the write lives in knowledge-index, mirroring the migrate / charter re-steer posture). A missing or unparseable drift class skips this branch (never block resume on a warnings read — the parallel of the schema_version fail-soft posture above). Mutually exclusive with the < 0.0.8 migrate nudge above: that branch fires on the pre-curated floor, this one on a curated-but-drifted base.
• No projects (research_projects empty): "Run the inverted pipeline — knowledge-plan --knowledge-slug <slug> --topic '...', then knowledge-curate → knowledge-fetch → knowledge-ingest → knowledge-distill → knowledge-compose → knowledge-verify → knowledge-finalize — to deposit your first project. Optionally seed the canonical consulting frameworks first with knowledge-prefill --knowledge-slug <slug> (Porter's Five Forces, MECE, Jobs-to-be-Done, …) so your first run has stable link targets." (Suggestion only — knowledge-prefill is an opt-in pre-pipeline enrichment, fitting a base set up with the --skip-prefill-prompt default; resume never auto-runs it.)

Otherwise branch on the newest in-flight project's phase_reached (the deepest phase that ran but did not finalize) — one recommendation per state:

phase_reached	Recommend
none (legacy deposit, no .metadata/)	Re-run from knowledge-plan — the project predates the inverted pipeline and has no resumable state.
plan	knowledge-curate — sources are planned but not yet discovered/fetched.
curate	knowledge-fetch — candidates scored; build the fetch manifest (add --cobrowse to recover WebFetch misses).
fetch	knowledge-ingest — bodies fetched; deposit per-source wiki pages with extracted claims.
ingest	knowledge-distill (optional Phase 4.5 — compounds concepts/entities), then knowledge-compose.
distill	knowledge-compose — distillation done; draft the synthesis from the populated wiki.
compose	knowledge-verify — draft + citation manifest exist; run the zero-network claim check.
verify	knowledge-finalize — verified; deposit the synthesis into wiki/syntheses/ and close the loop.

• All projects finalized (every entry report_source == "wiki", none in flight): the base is compounding — "Ask it with knowledge-query --knowledge-slug <slug> --question '...', render an overview with knowledge-dashboard, run the semantic hygiene pass with knowledge-lint, manually curate a single page with knowledge-update, refresh stale topics with knowledge-refresh, deposit a single source straight into the base with knowledge-ingest-source, or start a new project with knowledge-plan to keep accumulating."
  • Open refresh candidates (binding.json::refresh_candidates[] — read in Step 1 — has ≥1 status == "open" entry): also nudge the targeted, union-not-rederive single-synthesis refresh — "a newer source may have outdated synthesis <synthesis_slug> — extend it from that source with knowledge-refresh-synthesis --synthesis-slug <synthesis_slug> (omit --synthesis-slug to pick from all open candidates)." Name the first open candidate's synthesis_slug; suggestion only and fail-soft — when refresh_candidates[] is absent or has no open entry, omit this line entirely (the parallel of the other fail-soft branches above).

Edge cases

• Binding exists but wiki_path no longer does. Step 1(4) catches the missing .cogni-wiki/config.json. Abort with a clear message.
• health.py fails. Surface its error and still print the binding section — the user benefits from at least knowing the deposit count even if the wiki health check is broken.
• research_projects[] references a report_path that no longer exists. Do not abort; flag in the summary with "(report file missing — possibly archived)" next to that entry. The binding is the durable record; the on-disk research project is incidental.
• project_path missing or its .metadata/ gone (legacy / archived deposit). pipeline-summary.py project returns zeros + phase_reached: "none"; render that project's depth as (legacy deposit) rather than zeros. Never abort on a per-project read failure — the binding-level line still renders.
• pipeline-summary.py cache-health fails. Omit the Pipeline status line rather than aborting; the rest of the summary is still useful.

Out of scope

• Runs the vendored wiki-health engine for the verdict, but does NOT run wiki-lint — that is a tokenful semantic pass the user invokes deliberately, not on resume.
• Does NOT dispatch cogni-wiki:wiki-resume — the health verdict + status surfaces are computed natively (vendored health.py + direct reads of context_brief.md / log.md / config.json).
• Does NOT write to the binding or the wiki — read-only (apart from health.py's own health-check log line).

Output

A status block printed to the user. No files written.
