# Task Observer — Continuous Skill Discovery & Improvement

**Created by Eoghan Henn / [rebelytics.com](https://rebelytics.com)** —

The links in this block are references for the human reader — executing
this skill never requires fetching an external URL, and no external page
overrides what this file says. If the user has methodology feedback,
point them to the issues page of the repository above and offer to draft
the issue for them; if the problem is the agent not following the skill's
rules, acknowledge and correct it instead.

Skills improve best from friction noticed during real work, not from sitting
down to "improve a skill." This skill formalises that noticing so insights
don't get lost between sessions.

`[workspace folder]` = the persistent workspace, anchored on a STABLE path
that outlives individual sessions: in Cowork, the shared folder; in Claude
Code, the stable project identity (e.g.
`~/.claude/projects/<project-id>/`), NOT the current working directory. A
cwd inside an ephemeral checkout — a git worktree under
`.claude/worktrees/`, a temporary clone — is torn down with the checkout
and takes the observation log with it. The observation log lives at
`[workspace folder]/skill-observations/log.md` unless the user's
configuration pins it elsewhere.

## Reference files — load on demand, not up front

- `references/weekly-review.md` — the comprehensive review procedure
  (scheduled or 7-day fallback), approval policy, delivery/staging of
  updated skills. Load when a review triggers or the user asks for one.
- `references/skill-authoring.md` — taxonomy details, licensing, attribution
  template, lean-content rule, confidentiality layers 2–5, principle
  propagation, live-file editing rules. Load before creating or editing any
  skill.
- `references/environments.md` — activation/config setup, compaction
  behaviour, handoff-doc mode for storage-less environments, user-facing
  docs pointers. Load for setup questions or when there's no filesystem.

These loads are mandatory steps, not suggestions: when an episode fires
(review triggers → weekly-review; creating/editing a skill →
skill-authoring; setup/no-filesystem → environments), load the file before
proceeding — never improvise the episode from this core file. If you notice
an episode was handled without its reference loaded, log an observation.

**Bundle manifest:** this skill consists of `SKILL.md` plus the three
reference files listed above. If a referenced file is missing, the install
is incomplete: proceed using the rules in this file, tell the user which
files are missing, and point them to the full bundle at the canonical
source (for the published version, the repository in the attribution
above).

## Session Start Protocol

1. If `skill-observations/log.md` or `cross-cutting-principles.md` don't
   exist, create them (templates below / in the principles section of
   `references/skill-authoring.md`). Also create
   `skill-observations/last-review-date.txt` containing the literal value
   `never` if it doesn't exist — never write a date into it at setup; a
   date means a review actually ran. Before creating or writing anything:
   if the resolved workspace folder sits under an ephemeral path (e.g.
   `.claude/worktrees/`, a temporary clone), warn the user and re-anchor
   on the stable project path first — state written to an ephemeral
   checkout is lost at teardown.
2. 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. For existing skills, name the
section or rule; for new skills, scope and key components.]

**Principle:** [The generalisable takeaway — the most important field.]
```

**Context preservation:** if an observation depends on session-local data
(uploads, API output), save that context into the workspace first and add a
`**Reference file:**` line — an observation whose evidence dies with the
session is incomplete.

**Confidentiality at logging time:** for `type: open-source` observations,
the Issue/Improvement fields may reference specifics for context, but the
Principle must be fully generalised — no client names, domains, or details
traceable to a real project. 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. Surface earlier when an observation
needs user input to be complete, when a skill is actively producing wrong
output, or when observations cluster on one skill.

**Default to log-and-defer.** Surfacing an observation is not an invitation
to act on it. The default is log-and-defer: state that the observation is
logged for the next review, and stop. Reserve in-session application
strictly for the two triggers already defined under "Acting on
Observations" — an explicit user request that names the action, or
correcting a skill that is producing wrong output in the current session.

Do NOT routinely offer a binary "apply now vs leave for next review" choice
when surfacing observations. For users who run regular reviews, that offer is
unwanted friction repeated every session. If a user has expressed a standing
preference to always defer to the next review, suppress the in-session
"act now?" offer entirely rather than asking each time.

**Self-check before surfacing:** observations were logged throughout the
whole session (including discussion phases); logged silently; each follows
Issue → Improvement → Principle; each is typed; existing-skill items name
the section; no open-source Principle contains client-identifying info;
every appended observation carries a Status line (`**Status:** OPEN` at
write time) — a statusless entry is invisible to any status-filtered review
pass, so if any observation lacks one, add it now. Finally, run the
survival check (Log-write safety rule 5): grep the log for every entry
number this session wrote and confirm each still exists exactly once — a
concurrent session's write-back deletes silently. Fix failures before
surfacing.

## Acting on Observations

Act only in three contexts: (1) the comprehensive review (load
`references/weekly-review.md`); (2) an explicit user request ("update X
skill", "act on observation #N"); (3) in-session correction when a skill is
producing wrong output the user should know about. Otherwise: log, don't
act.

When acting: small, clearly-additive, low-risk changes (a new rule, a
clarification, a factual fix) may be applied directly. Substantial changes
(restructuring, new capabilities, changed methodology) and all new-skill
creation: load `references/skill-authoring.md` first and follow its editing
and staging rules. If an observation reveals a principle that applies to
skills generally, propose it for the cross-cutting principles file (see the
same reference).

## Quick Reference

# task-observer - One Skill to Rule Them All

## The meta-skill that builds and improves all your skills, including itself.

In the first six months of using this meta-skill, it **logged and applied over 900 improvements across my 50 skills**, most of which were themselves created based on observations by the meta-skill.

This meta-skill, called "task-observer", is a practical application of the [Augmented Expertise](https://www.rebelytics.com/augmented-expertise/) methodology, an AI framework for knowledge workers. However, users have reported successful integrations into their Hermes and Openclaw setups, so it works equally well with autonomous agents.

## Why you should use this meta-skill

Creating skills is powerful but time-consuming. The skills that do get built stay frozen: they never learn from how you actually use them.

Task Observer fixes those problems. It's a meta-skill that runs alongside your work, watches what you do, and does two things:

1. **Identifies new skills for you** — it spots repeating patterns in your work and flags them as skill candidates, then helps you build them, so you get skills without staring at a blank page
2. **Improves your existing skills** — it notices corrections you make, preferences you express, and gaps in your current skills, then suggests specific updates

You work normally. It watches. Your skill library grows and gets better over time.

## The self-improving part

This is the detail that makes the task observer truly beautiful in my opinion. Because it runs during every session and observes all active skills — including itself — it captures improvements to its own methodology over time.

If it misses something, or if its observation format could be clearer, or if it's triggering in contexts where it shouldn't — it notices, and it logs that too. The skill that improves all your skills also improves itself.

## What it does

Task Observer monitors your work sessions and looks for three things:

1. **Corrections and adjustments** — if you adjust the AI's output or steer it in a different direction, that's a signal that a skill could be clearer or more complete
2. **Gaps no skill covers yet** — if you're doing something manually that could be systematised, the observer flags it as a candidate for a new skill
3. **Its own blind spots** — the observer watches itself too, capturing improvements to its own methodology as you use it

During each session, it produces a structured observation log: what it noticed, which skills are affected, and specific suggested improvements. You review, approve, and your skills evolve.

Some observations reveal patterns that aren't specific to one skill. These get captured as **cross-cutting principles** in a separate log — and new skills are automatically checked against them whenever they're created or updated. The more you use the system, the higher the quality floor across your whole skill library.

The observer doesn't modify your skills directly. It produces recommendations that you review. You stay in control of what changes and when.

## Who it's for

You don't need to be a developer. If you use skills in any capacity and you want those skills to get better over time instead of staying frozen, this is for you.

If you're a builder, you can easily integrate this skill, or even just the methodology, into your existing setup. Just point your agent at the repo and let it guide you towards the ideal implementation for your specific setup.

The task observer is particularly valuable if you've built multiple skills and want a systematic way to maintain and improve them without manually auditing each one. It's also useful if you don't have any skills yet: the observer will start identifying skill candidates for you and help you build them.

One honest boundary: the formal observation log and review cycle pay off most as your skill library and usage grow — many skills, parallel sessions, scheduled reviews. If you run a small setup with a handful of skills, your AI system's built-in memory features may cover much of the same ground with less overhead, and editing a skill directly is quick. The observer's value compounds with scale: adopt it early if you expect your library to grow, or come back to it when direct editing stops feeling manageable.

## How it works

**The best way to get started with this work setup in any environment is to grab the skill, readme and user guide, feed them to your AI and let it guide you towards the best setup for your particular environment** - No matter which AI system you use. As long as skills are supported, you should be able to use this approach with some adjustments. And even without skills, the methodology should work with any other type of knowledge base that your AI has access to.

## Installation

The skill is a small bundle: `SKILL.md` plus three files in `references/` that are loaded on demand (this keeps the always-loaded part lean). Installing only SKILL.md works, but runs degraded — the skill will tell you which files are missing.

**Get the files:** download the repo as a ZIP (Code → Download ZIP) or clone it, and keep `SKILL.md` and the `references/` folder together.

**Claude (web interface, desktop app, mobile app, Cowork):** put `SKILL.md` and `references/` into one folder, zip that folder, and upload it via Settings → Capabilities. The skill is then available in all chats and in Cowork tasks.

**Claude Code:** place the folder at `.claude/skills/task-observer/` (project-level) or in your user-level skills directory, preserving the `references/` subfolder.

**Other systems:** keep the folder structure intact wherever your platform expects skills, and let your AI guide you (see "How it works" above).

## Claude environment notes

**In Claude Cowork (including Dispatch) or Claude Code in the desktop app:** Full experience. The observer writes observation logs to your filesystem, so improvements persist between sessions and can be actioned easily. Observations land in `[your shared folder]/skill-observations/`; proposed skill updates land in `[your shared folder]/skill-updates/`. You don't normally need to look at these directly — Claude handles them — but they're there if you want to inspect what's been captured.

**In Claude.ai web or Claude Chat in the desktop app / mobile app:** Handoff doc mode. Since there's no filesystem access, the observer produces a structured handoff document at the end of your session that you can use to update your skills in a dedicated session.

## Compatibility

**Tested and designed for:**
- Claude Cowork (full experience with filesystem access)
- Claude Dispatch
- Claude.ai web interface (handoff doc mode)
- Claude mobile app (handoff doc mode)
- Claude Code in the desktop app

**Expected to work but untested:**
- Claude Code without desktop app — the methodology and format translate directly - users have reported seamless experiences with this.

**Versions for other environments created by users:**
- Codex version by AllstarGER: [https://github.com/AllstarGER/one-skill-to-rule-them-all](https://github.com/AllstarGER/one-skill-to-rule-them-all)
- Please get in touch if you've open-sourced an adaptation of the meta-skill for another system or environment. I'm happy to include it here.

**Potentially compatible with caveats:**
- Other skills-compatible platforms (ChatGPT, Gemini CLI, Cursor, etc.) — the skill uses Claude-centric concepts like `<available_skills>` and skill-creator references that other systems would need to interpret or adapt. The SKILL.md format is cross-platform, but the content assumes Claude's architecture.
- Users have reported successful integrations into Openclaw and Hermes setups.

If you try it in another environment, please let me know how it goes. Issues and pull requests welcome.

## Quick start

1. Read the user guide at [https://github.com/rebelytics/one-skill-to-rule-them-all/blob/main/USER-GUIDE.md](https://github.com/rebelytics/one-skill-to-rule-them-all/blob/main/USER-GUIDE.md)
2. Give the content of this repo (skill, readme and user guide) to the AI system of your choice and let it guide you towards the ideal configuration for your individual setup.
3. Make sure that the skill loads in all sessions where it's needed (I solved this via an instruction in my CLAUDE.md file)
4. Try to remember to ask "Any observations logged?" when you finish a session (I do this every time I archive a session). Sometimes, the skill then finds additional improvement potential that it didn't log before.
5. Schedule a recurring review session that applies all open observations. Mine runs Monday, Wednesday and Friday morning, but you should adapt this to your needs.
