Scan OPEN observations and active principles; hold them in awareness, + don't surface unprompted. +3. Read `skill-observations/last-review-date.txt`. The value carries the + truth: a date = when the last review actually ran; `never` = no review + has run yet. A missing file is abnormal (step 1 creates it) — recreate + it with `never`, don't invent a date. If the value is `never` or older + than 7 days AND there are OPEN observations: in an interactive session, + offer the review in one line ("the observation backlog hasn't been + reviewed [in N days / yet] — run it now, or carry on with your task?") + and proceed with the user's task unless they opt in; never gate their + work on the review. Only a scheduled/autonomous run loads + `references/weekly-review.md` and runs the review unprompted. +4. Once per session: if no CLAUDE.md (or equivalent) activation instruction + for this skill exists, briefly suggest adding one (see + `references/environments.md`). Skip if already configured. +5. Note the log's modification time. If modified in the last few hours, + another session may be writing to it — re-read immediately before every + append, never trust a remembered "current number". + +## When to Observe + +Active for the entire task session: execution, post-task feedback and +review discussion, meta-discussion about skills or methodology, and +reflective/strategy conversations about how work should be done. **The +observation mindset does not deactivate when the conversation shifts from +doing the work to discussing it** — user feedback in review phases is often +the highest-signal input. Inactive only for casual conversation and quick +factual questions with no tools or deliverables involved. + +## What to Watch For + +**Signals for a NEW skill:** a reusable multi-step workflow; a methodology +the user explains that no existing skill captures; a recurring task type +with similar structure; a process with clear inputs, phases, outputs; the +user describing a refined process ("I always do it this way"); a structured +approach emerging naturally during work. + +**Signals for IMPROVING an existing skill:** anything from a task that used +a skill and could make it better — problems, positive signals, or neutral +gaps. Examples: the agent violates a documented rule (the skill needs +enforcement, not louder rules); a user correction reveals a missing rule or +edge case; a better workflow emerges than the skill recommends; a technique +works well enough to promote from incidental to recommended; an undocumented +use case; feedback that generalises; a wrong assumption; new tooling +obsoletes a step; corrections forming a pattern; a principle that applies to +other skills too; a naming/framing/structural suggestion, even +conversational. + +**Signals for SIMPLIFYING a skill:** a section never relevant across many +sessions; a rule from a single unvalidated observation; workflows users +consistently shortcut; sections loaded but never acted on; contradictory +rules; "just in case" complexity that never triggered; a rule the agent +consistently fails to follow (convert to structural enforcement — checklist, +verification step, unskippable tool call — or remove it). Treat these as a +review checklist; ask "what can we remove?" as deliberately as "what should +we add?" + +**Do NOT log:** one-off corrections that don't generalise; preferences +already captured in a skill; tool bugs unrelated to methodology; +observations that would need proprietary client information to be useful in +an open-source skill (unless an internal skill is the right home). + +## How to Log + +Append to the log **silently, within the same turn or the next** — never +batch mentally for later; the act of writing is the enforcement mechanism. + +**Mandatory observation checkpoint after every 3rd TodoWrite completion:** After +marking the 3rd, 6th, 9th (etc.) TodoWrite item as completed in a session, you +must **write to the log** — not merely pause to ask yourself a question. Either +append any pending observations, or, if genuinely none have accumulated, append +an explicit acknowledgement marker (a one-line `no observations` note for that +checkpoint). The required action is a concrete log write; a remembered "ask +whether" is not enforcement. This is a hard checkpoint, not a suggestion — the +skill has demonstrated that softer "check when completing items" or "pause and +ask" guidance gets lost during cognitively demanding analytical work, exactly +when the most observations accumulate. The count doesn't need to be precise; +the rule is: roughly every third completion, write to the log (observations or +the acknowledgement marker). The write itself is the enforcement mechanism: it +forces the mental check to surface as a recorded action, and it prevents the +common failure mode where the skill is loaded but no observations are written +until the user explicitly asks. + +**Deliverable-event flush:** Hard enforcement that hooks onto tool calls you are +already making is the only reliable mechanism; soft prompts that rely on memory +don't survive cognitive load during long substantive sessions (when the most +insights surface). So tie observation-flushing to deliverable and workflow events +that already involve a tool call. Whenever you present or render a major +deliverable — `present_files`, a deck or PDF render, a staged skill file handed +to the user — or complete a task/todo batch, flush any pending observations to +the log at that moment, before moving on. These are natural, already-occurring +checkpoints; piggy-backing the flush onto them means the write happens as a +side effect of work you were doing anyway, rather than depending on a separate +act of memory. + +**Numbering discipline (mandatory, every append):** + +1. *Pre-check:* read the actual log and find the highest existing number — + never trust session memory: + + ```bash + # GNU grep: + grep -oP '### Observation \K\d+' log.md | sort -n | tail -1 + # macOS / POSIX: + grep -o '### Observation [0-9]*' log.md | grep -o '[0-9]*' | sort -n | tail -1 + ``` + +2. *Pre-write assertion:* immediately before appending, confirm the proposed + number doesn't already exist: + + ```bash + PROPOSED=$(( $(grep -oP '### Observation \K\d+' log.md | sort -n | tail -1) + 1 )) + grep -qE "^### Observation ${PROPOSED}:" log.md && { + echo "COLLISION on #${PROPOSED}"; exit 1; } + ``` + + If it fires, increment past all existing numbers and re-check (and log a + meta-observation — it signals a parallel-session collision). + +3. *Post-write verification:* after appending, count occurrences of the + number; if >1, a parallel writer collided between check and write — + renumber YOUR entry to max+1. Identify your entry from your own append + operation (capture the file's line count immediately before and after + your `>>`; your entry starts at the old line count + 1) — do NOT + re-grep and take the last occurrence, which may be a colliding writer's + entry appended after yours. After any `sed` renumber, re-read the + affected line to confirm the substitution actually took effect — a + line-addressed `s///` whose target shifted finds no match and still + exits 0. Pre-write catches stale reads; only a post-write check catches + the race. The pattern for shared logs written by parallel agents is + check-then-act-then-verify. + +**Log-write safety — never let a mutation span entry boundaries:** When +mutating the log programmatically (marking entries ACTIONED/DECLINED, +archiving, renumbering), a greedy or DOTALL pattern over the whole file can +silently swallow everything from one match to EOF. This has happened: a +`.*$` under `re.S` over the multi-entry file captured from one entry's +Status line to end-of-file and overwrote 16 later entries in a single +substitution. The log is shared state across many entries; mutate it one +bounded entry at a time and verify every mutation. + +1. **Re-read and merge immediately before any write-back.** Any full-file + rewrite (archival, renumbering, reassembly from chunks) built from a + snapshot destroys whatever concurrent sessions appended after that + snapshot — the write-back succeeds, the victim gets no error, and the + loss is invisible. This has happened in production: a parallel session's + write-back erased two entries appended minutes earlier, hours after the + exact failure mode had been documented. So: take the snapshot, prepare + the mutation, then — immediately before writing — re-read the live log + and diff against the snapshot. If new entries appeared, merge them into + the write-back (or rebuild from the fresh read). Never write back a + stale snapshot. + +2. **Isolate the target entry, or anchor to a single line.** Either split + the log on `### Observation N:` headers, edit the TARGET entry's chunk in + isolation, and reassemble — OR, for a status-only edit, use a strictly + line-anchored multiline substitution that cannot cross a newline, e.g. + `re.sub(r'(?m)^(\s*-?\s*)\*\*Status:\*\*.*$', ...)` (multiline `^...$` + bounds the match to one line). NEVER use a DOTALL/greedy pattern across + the multi-entry file. + +3. **Assert a structural invariant against the LIVE pre-write file.** Count + `### Observation` headers in the live file immediately before writing and + again after. For a status-only edit the count MUST be unchanged; for + archival or append it must change by exactly the expected number. The + baseline must be the live file at write time, NOT your session's earlier + snapshot — an invariant computed against a stale snapshot validates that + you wrote what you intended while still destroying what others wrote in + between. Fail loudly if the count is off. + +4. **Keep the pre-write backup.** Copy `log.md` before any programmatic + mutation. This is what made full recovery trivial when the truncation + above occurred — it turned a destructive bug into a non-event. + +5. **Verify your entries SURVIVED, not just that they were written.** A + successful append proves nothing an hour later — a concurrent session's + write-back can silently delete it, and only the destroying session gets + any signal (none). Before surfacing observations at session end, grep + the log for every entry number this session wrote and confirm each still + exists exactly once; re-append any that are missing (with fresh numbers) + and log a meta-observation about the collision. + +Principle: a log shared across many entries must be mutated one bounded +entry at a time; every rewrite must be based on a fresh read, verified by a +structural invariant against the live pre-write file, and backed up. Writers +must verify survival, not just successful writes — in a concurrent erase, +the victim gets no error. + +**Format and insertion:** always `### Observation NNN:`, always appended to +the END of the log, never mid-file, never alternative ID formats. One +format, one insertion point. **Every new observation MUST include +`**Status:** OPEN` as its first field — this is mandatory at write time, not +optional.** Reviews classify entries by their Status line; an observation +written without one is invisible to any status-filtered pass and risks being +silently skipped instead of triaged. + +```markdown +### Observation [N]: [Short descriptive title] + +**Status:** OPEN +**Date:** [date] +**Session context:** [what task was being worked on] +**Skill:** [existing skill name, or "New skill candidate: [working name]"] +**Type:** [open-source | internal] +**Phase/Area:** [which part of the skill or workflow] + +**Issue:** [What happened — specific enough to understand weeks later +without the original conversation.] + +**Suggested improvement:** [Concrete change.

Full confidentiality layers for skill +authoring: `references/skill-authoring.md`. + +## Referencing Observations + +When citing an observation by number — in conversation, in a review report, +or from within another observation — the number must come from the entry's +literal `### Observation N:` header line. Never cite an observation number +that wasn't read from that header. + +- **Search-tool line numbers are positional metadata, not IDs.** `grep -n` + prefixes every match with a line number; when a match lands mid-entry + (e.g., on a Session context or Principle line rather than the header), + that line number is NOT the observation number. Resolve to the owning + header first — scan backwards from the matched line to the nearest + preceding `### Observation N:` header and take the number from there + (e.g., an awk backwards-scan, or re-grep for `^### Observation` and pick + the last header line before the match). +- **Plausibility check (cheap second layer):** before quoting any + observation number, compare it against the known counter range — the + highest `### Observation N:` header in the log. A number outside that + range (e.g., citing #1365 when the log's counter is at #766) is almost + certainly a line number or other positional artefact misread as an ID. + +The general rule: IDs must come from the record's own identifier field, +never from the positional metadata of the search tool that found it. + +## Taxonomy (quick version) + +**Open-source** — client-agnostic, methodology-driven, useful to other +practitioners. **Internal** — contains user/client/project specifics or +personal preferences. Default to open-source when it could go either way, +stripping specifics. The boundary is also a confidentiality boundary. Full +requirements (attribution, licensing, structure): `references/skill-authoring.md`. + +## Archival on Write + +On every log write, first move already-resolved entries to +`skill-observations/archive/log-[YYYY-MM-DD].md` (preserving the log header +in the archive). "Already resolved" is decided by date, read from the file: +a resolved status MUST record its date — `ACTIONED (YYYY-MM-DD) — [what was +done]` / `DECLINED (YYYY-MM-DD) — [reason]` — and archival moves only +entries whose recorded date is before today. Entries resolved today stay in +the active log until the next day, no matter which session resolved them: +the grace period lives in the file, never in session memory, so it holds +across parallel and subsequent sessions. A resolved entry with no readable +date gets today's date added instead of being archived. The active log +keeps its header, status key, all OPEN entries, and the same-day-resolved +ones. + +Archival is a read-filter-rewrite — the highest-risk mutation the log +undergoes, and the one that has destroyed concurrent appends in production. +It MUST follow the full Log-write safety sequence above: backup, re-read +the live log immediately before writing back and merge any entries that +appeared since the snapshot, then verify the post-write header count equals +the live pre-write count minus exactly the number of archived entries. + +## Log Structure + +```markdown +# Skill Observation Log + +Observations captured during task-oriented work. + +**Status key:** OPEN = not yet actioned | ACTIONED (YYYY-MM-DD) = skill +updated/created | DECLINED (YYYY-MM-DD) = user decided not to pursue — +resolved statuses always carry their resolution date + +--- + +## [Date] + +### Observation 1: [Title] +**Status:** OPEN +[... full format ...] +``` + +## Surfacing Protocol + +Default: at end of session, as a grouped summary — improvements grouped by +skill, new-skill candidates listed separately; for each, one sentence plus +suggested type; ask which to act on.

Required +elements: the body identifies itself as open-source; author attribution +block (template below); a licence statement; a feedback/support section +routing methodology feedback to the creator; tool-agnostic language +(capabilities like "browser access", not product names); built-in +enforcement (see Pre-Flight Principle). Default to open-source when a skill +could go either way — strip specifics and generalise. + +**Internal skills** contain user/client/project specifics, personal +preferences, or context only the user has. They identify themselves as +internal, need no attribution or licence, and can be shorter and less +formal. They're working documents — keep them current, don't over-engineer. + +## The Pre-Flight Principle + +Rules documented in a skill are not reliably followed during creative flow. +Every skill with explicit rules needs a verification step where the agent +re-reads the rules and checks its output against them before delivery. When +creating or improving any skill ask: "Does it have rules? Does it have a +mechanism to enforce them?" If not, add one. + +**Embedded commands are pre-flight items too — execute before you ship.** +Prose rules and command snippets fail differently: a prose rule is +re-interpreted in context on every run, so ambiguity can be caught at +execution time; an embedded command runs verbatim, unattended, forever — +and a subtly wrong command can read as correct on every re-read +(`git log -1 --format=%cI --reverse` returns the NEWEST commit, because +`-1` applies before `--reverse`, while the plausible reading is "oldest"). +Any command embedded in a skill must be executed once against real data, +with its output inspected for plausibility, before the skill file is +saved. An unverified snippet is among the highest-risk lines in a skill: +it ships bugs that no re-read can catch. + +## Lean Content + +A skill should contain only content that changes the agent's behaviour at +execution time. Move changelogs, credits beyond the author block, long +backstories, and maintainer notes to supporting docs. Do NOT cut examples, +anti-patterns, or worked scenarios — bare rules get violated more than +rules with context. Test: would removing it change behaviour? Keep +per-session rules in the skill body and episodic material in reference +files loaded on demand (progressive disclosure) — a skill loaded every +session is fixed overhead and should be audited like one. + +## Licensing + +Include a licence statement in the preamble and a LICENSE file with full +text. Options: **CC BY 4.0** (prose/methodology skills; share and adapt +with credit — recommended default), **MIT** (code-heavy, permissive), +**Apache 2.0** (MIT plus patent grant), **CC BY-SA 4.0** (share-alike +derivatives), **GPL family** (strong copyleft). The author chooses; the +requirement is that there is one. + +**Private client sharing** is a third channel with its own rights framing: +a client-agnostic skill shared privately with one client is NOT open source +and NOT internal. Keep the attribution block; replace the licence statement +with a short usage notice (e.g., "shared privately for internal use; please +don't redistribute without checking with the author"); no LICENSE file +needed. All confidentiality sweeps still apply — other-client information +must not leak even when the recipient is a known client. Do not treat "not +internal" as "therefore open source": distribution channel determines the +rights framing, not just the feedback routing (see the distribution-channel +note below). + +## Author Attribution Template + +```markdown +**Created by [Author Name] / [website or contact link]** + +[1-2 sentence description of what the skill does and its provenance.] + +**Licence:** This skill is released under [LICENCE NAME].

Direct contact: [contact link]. If feedback stems from the +methodology, log it and suggest sharing it; if from the agent not following +the skill's rules, acknowledge and correct. +``` + +**Distribution-channel note:** the template's feedback routing assumes +public-repo distribution. Only reference a repository URL once that +repository actually exists — never write a reference to an artefact before +the artefact exists. Until publication, route feedback to direct author +contact only; when the skill is published, inject the repo URL at publish +time. When an open-source skill is distributed privately (shared directly +with a client rather than published), keep the direct-author-contact +routing — a public-repo reference is wrong for that channel. + +## Confidentiality layers + +The open-source/internal boundary is a confidentiality boundary; enforce it +in layers so any one catches what others miss: + +1. **Observation-level stripping** — open-source observations carry a fully + generalised Principle (covered in SKILL.md). +2. **Pre-creation review** — before drafting/regenerating an open-source + skill, scan all source material for client names, URLs, domains, + internal terminology, identifiably-specific structures; replace with + generic equivalents first. +3. **Post-draft sweep** — a separate re-read focused only on leakage: + proper nouns besides the author, domains/URLs/project identifiers, + vertical details that narrow the client, examples traceable to a real + project. +4. **Structural principle** — when in doubt, remove. Slightly more generic + beats slightly leaky. +5. **Cross-product re-identifiability sweep** — the final pass before any + public release. Individually-sanitised examples can combine to identify + a client (enumerated counts matching a public client list; specific + numbers in a thin vertical; thinly-disguised placeholder names in the + same vertical as a real client). List every example and its fields + (vertical, geography, numbers, timing, counts); ask whether a reader + with the author's public client list could map them; mitigate by + blurring counts, widening verticals, using illustrative ranges, or + consolidating into composites. Run this mechanically — the author is the + least reliable judge because they know the ground truth. + +## Editing skills — always start from the live file + +1. The live file is the authoritative source: in Claude Code, + `~/.claude/skills/{skill}/SKILL.md`; in Cowork, a read-only mount at + `.claude/skills/{skill}/SKILL.md` (writes fail with EROFS by design). + Do not edit skill files in place, in any environment — staging-only is + what keeps the autonomous review safe. +2. Always base edits on a fresh read of the live file — never a workspace + copy, prior draft, or memory. +3. Before overwriting any staged/workspace copy, diff it against the live + file; if they differ, rebase your edits on the live version. (Observed + failure: an update built on a stale snapshot silently dropped two + sections added to the live skill the same day; only a pre-merge diff + caught it.) +4. Stage every update to + `[workspace folder]/skill-updates/[date]/[skill-name]/` — the FULL + skill directory (SKILL.md plus references/, scripts/, assets/ where + present), never SKILL.md alone — and present it for review and + installation; nothing goes live until the user installs it. Where no + presentation/upload tool exists (e.g. Claude Code CLI), present the + staged path and a change summary in chat instead; staging-only applies + in every environment — it's the review loop's safety property, not a + filesystem constraint. For any + skill with supporting files, zip the staged directory into a `.skill` + bundle and present the bundle, never the bare SKILL.md: a single-file + delivery convention applied to a multi-file skill truncates it + silently (the install succeeds, the skill loads, and the missing + pieces only surface when a reference load or script call fails + mid-task). **Pre-delivery gate — two items, checked at the moment of + delivery, not just at drafting time:** (1) every `references/`, + `scripts/`, `assets/` path in the staged SKILL.md body has its file in + the staged set; (2) if the skill is multi-file, the delivery artefact + is the `.skill` bundle — bare file links fail this gate even when all + files are staged. (Reading this rule while drafting does not enforce + it at delivery; run the gate as the last step before presenting.) + Packaging hygiene: before zipping, sweep the staged tree for build + artefacts (`__pycache__/`, `*.pyc`, `.DS_Store`, `.~lock.*`) left by + in-session checks, and read the archive listing back after zipping — + the listing is the cheap verification that catches leaked artefacts. +5. When seeding a staged copy by copying from the read-only mount, reset + write permissions immediately (`chmod -R u+w` on the staged path, or + `cp --no-preserve=mode`) — the mount's read-only mode travels with + the copy, for directories as well as files, and the follow-up edit + otherwise fails with a permission error. +6. Match process rigour to the change: complex/open-source/uncertain design + → use the skill-creator if available; internal skills with requirements + already established in conversation → write directly, flagging + substantial changes for review. + +## Verifying relocations and restructures + +When content is relocated verbatim (splits into core + references, merges, +restructures), "nothing was lost" is checkable mechanically — but only with +a two-tier check: + +1. Enumerate every added/moved line via `diff` of the old base vs the new + base. +2. Exact-match each non-empty line against the restructured file set + (`grep -F`). +3. For misses, substance-check via a distinctive mid-line substring before + concluding loss — most misses are container artifacts (heading-level + changes, list-to-prose adaptation, re-wrapped lines splitting a phrase + across newlines), not real losses. +4. Word-count sanity check per file. + +One tier alone either misses losses (substance-only) or cries wolf +(exact-only). Additionally, inventory the original's enforcement +mechanisms (checkpoints, assertions, invariants, mandatory-write rules, +defaults) as an explicit checklist — compression preferentially destroys +enforcement machinery because it reads as redundancy — and sweep any "pure +restructuring" change for net-new behaviour, which hides well in a large +rewording diff. + +## New skills + +Use the skill-creator when available, passing the observation(s) as the +brief.

Otherwise: check +`skill-observations/scheduled-review-decline.txt`: if under 30 days old and +the fallback isn't firing repeatedly, skip. Check for a registered +scheduled task (scheduler presence or +`skill-observations/scheduler-registered.txt`); if found, skip. Before +offering, check reachability (see the regimes above): if the platform's +scheduler runs where it cannot reach the workspace folder (regime 2), do +NOT offer registration — recommend the calendar-reminder-plus-manual- +trigger pattern instead, and skip the rest of this step. Otherwise +offer to set one up. Yes → register via the platform scheduler (Cowork: +`create-shortcut` / `set_scheduled_task`; terminal: cron), name it +`weekly-skill-review`, use the draft prompt at +`skill-observations/scheduled-task-draft.md` if present, then verify the +registration actually succeeded (the scheduler lists the task, or the +platform confirmed creation) BEFORE writing today's date to +`scheduler-registered.txt`. If registration fails or can't be verified, do +NOT write the marker — the marker would permanently suppress the fallback +while no review ever runs. Tell the user registration failed and leave the +fallback active. No → write today's date to +`scheduled-review-decline.txt` (suppresses for 30 days; repeated fallback +firings within the window re-surface the offer). No scheduler available in +this environment → skip silently. + +**Step 1 — load.** Archive entries resolved in *previous* sessions (see +Archival on Write in SKILL.md). Read the observation log. + +Build the work queue from the structural identifiers, not from a status +filter. The OPEN set is defined as: **status is literally OPEN, OR the +observation has no Status line at all.** Concretely: + +1.

For each header, classify the entry's status by looking for a + `**Status:**` line within its body. Treat a missing, blank, or any + non-ACTIONED / non-DECLINED status as OPEN. +3. Never derive the work queue from a `grep '**Status:** OPEN'` alone. + Derive it from the header list minus the resolved (ACTIONED / + DECLINED) entries. A grep on an optional field silently drops every + entry missing that field — the review then confidently reports a + clean log while a backlog of untriaged observations is skipped. + +**Reconciliation guard:** before proceeding, assert that +`count(### Observation headers) == count(status-classified entries)`. +If the counts differ, the delta is statusless entries — surface and +triage them (as OPEN) rather than proceeding as if the log were clean. + +Also read all active cross-cutting principles. If there are no OPEN +observations and no outstanding principles: report "no open observations +or outstanding principles", update the timestamp, and stop. + +**Step 2 — inventory skills.** List all skills (system prompt +`` or the skills directory). Only user-owned custom +skills can be updated. Known read-only system skills: docx, pdf, xlsx, +pptx, skill-creator, schedule (grow this list when an update fails for +permissions). Observations targeting a system skill are NOT skipped — route +them to a complementary user-owned `{system-skill}-extras` skill containing +only the delta, creating it if needed and noting the pairing in +configuration. + +**Step 3 — cross-check observations.** Evaluate every OPEN observation +against every skill — not just the skill named in its header; Principles +often generalise. Build skill → [relevant observations]. Interactive: +present all of it and await approval. Autonomous: apply the approval policy +above and continue. + +**Step 4 — cross-check principles.** Flag every skill that doesn't yet +comply with each active cross-cutting principle. + +**Step 5 — apply.** For each skill with approved/non-escalated items, +produce an updated SKILL.md: integrate insights into the sections where +they belong (never append an observations list at the bottom); preserve +structure, voice, and attribution; place new rules where they logically +live. Follow the editing rules in `references/skill-authoring.md` (live +file as base, staging, diff-before-overwrite). + +**Step 6 — mark ACTIONED.** Update each applied observation's status: +`ACTIONED (YYYY-MM-DD) — Applied to [skill-name] (weekly review)`. The +date immediately after the status word is load-bearing: archival is gated +on it (entries archive only when it's before today), so a dateless mark +breaks the cross-session grace period. Do NOT archive same-session — the +next log write on a later day archives them. + +**Step 7 — timestamp.** Write today's date to +`skill-observations/last-review-date.txt`. + +**Step 8 — deliver and summarise.** Stage updated skills (see Delivery +below), then present: + +``` +## Weekly Skill Review Complete — [date] + +Updated skills ([N] observations, [N] principles applied): + +**[skill-name]** — [1-sentence change summary]; observations #[N], #[N] + +### Observations Actioned +[numbers and titles] + +### Skipped (needs manual review) +[items with reasons] +``` + +Wait for the user to acknowledge before other work. + +## Constraints + +- Don't modify observation entries beyond their status field. +- Don't create new skills in a review — note candidates for the user to + action via the skill-creator. +- Unsure how to integrate an observation → skip it and say so in the + summary. +- Treat internal observations with the same rigour as open-source. + +## Delivering updated skills + +Save each updated skill to +`[workspace folder]/skill-updates/[date]/[skill-name]/` — the FULL skill +directory (SKILL.md plus references/, scripts/, assets/ where present), +never SKILL.md alone — and present it for review and installation.

For any skill with +supporting files, zip the staged directory into a `.skill` bundle and +present the bundle; a bare SKILL.md install silently truncates a +multi-file skill.
